If you've been keeping up with the most recent.NET advancements over the past year, you've probably heard Blazor mentioned a few times. JavaScript has never made us happy, even though it is now the de facto language for front-end development. How many supersets or translations of JavaScript have been developed over time to make JavaScript more maintainable?
The most widely used language among programmers is TypeScript. Anders Hejlsberg was the designer. He was the same person who developed C#. The updated version includes generics, type checking at compile time, interfaces, and classes. Since many years ago, C# has already included all of these features as well as many more. C# is versatile and offers a tonne of solid components. Learning it is also simple.
Web Application Development
Web Application
Web applications are computer programs that use the browser for specific tasks. The web application communicates to the server side for data processing through an HTML request, AJAX or API. Server-side scripts and client-side code are the two main components of any web application. Server-side scripts are used to retrieve and store data in these apps. It also uses client-side scripting to display the data that is retrieved from a server script.
Web Application Development
Many businesses have been attracted to web application development due to its many advantages over traditional websites. Web applications allow for a high level of customization without having to change the system as a whole. Both server-side scripts and client-side versions are independent of each other, so there's no interruption when making changes to a UI.
The web application has evolved from a static website to one that offers features almost similar to a mobile app. Mobile applications may be faster, and they provide native functionality. However, users must update them regularly.
Web applications, on the other hand, update themselves automatically and can be accessed by users across all devices without any installation. Microsoft web application development is, therefore, a more appealing option for many organizations. The adoption of web applications has been massive across many business sectors, including music streaming giants such as Spotify and video streaming apps such as Netflix. You must plan your web development carefully to get the most out of browser-based experiences.

Pros of Web Application Development
Easy Access
Web applications are convenient because you do not need to install or download any software. You only need a browser and your URL. The setup is simple. You can also access the application from any platform, including Windows, Mac OS, Linux, Android, and more. The web application is responsive, meaning that it will automatically adjust to any screen size whether you are using a mobile device, tablet, or web browser.
Cost-Effective
You don't have to perform any complicated tasks when developing web applications. It is easy to link the URL with the web application. This is because the process requires little time and effort. Easy customization is another factor that contributes to cost-effectiveness. Developers can easily customize the interface of a web application. It requires less resources and effort, which reduces the cost of development.
Keep Up to Date
The web application does not require external updates like desktop and mobile apps. The latest version will be displayed on the URL or website to which it is linked. Anyone can view this anytime, anywhere. The web application will always be up to date so that all users can access the most recent version.
Faster Deployment
Every application will eventually require an update. It can be to fix a bug or introduce new features. In this case, deployment is a crucial component. You can update web apps through your host server without interrupting client machines. End-users have access to the most recent version of web applications without downloading.
Scalable and Customizable
It isn't easy to customize software development without spending a lot of money on upgrades. Web apps are different. They can be customized to meet your business requirements and scaled up or down as needed.
Here, customization means creating your branding, setting permissions and roles, adding functions specific to your company, etc. Scalability and customization will allow you to develop new features quickly while facilitating user growth without having to compromise performance.
Cons of Web Application Development
Internet Access is a Necessity
Web application development relies on Internet access, which is one of its downsides. The website will only load if the user has an internet connection. PWAs (Progressive Web Application) are a great way to avoid this problem. They only require the user to install them once, and they don't need an active connection. You can save changes online and use some features offline. You might need the internet in the worst-case scenario.
Reduced Speed
Web applications are usually slower to operate than local apps. If your web server is performing as you would like, then the web app will negatively affect the user's experience. The web application's size increases when it is linked directly to the browser. This reduces the speed of development, execution and the loading time.
Requires Responsive Design
The web application can be used on a variety of browsers and mobile devices. You must have a responsive web design. In the absence of this, your web collaborative application will not be able to adjust to various browsers or screen sizes. There will also be concerns about the compatibility of your web app with different browsers and devices.
Safety Issues
Data security is a concern for every enterprise today. A breach in the Server is a significant security issue for web applications. In some cases, not adhering to government standards and practices can lead to such situations.
The most frequent security threats on web applications include man-in-the-middle (MiTM), XSS, DDoS, and SQL injection. Every single day, security forums report a problem. It takes a lot of effort on the part of developers to safeguard online applications against security risks.

Web App Development with Microsoft Blazer
Microsoft Blazor, a Microsoft Framework that allows developers to create full-stack exchange applications without having to write JavaScript code, has shown its potential to be a very efficient and productive model. It is a competitor for JavaScript frameworks which offer single-page application frameworks.
Microsoft has already conducted multiple Blazor experiments, including with desktop apps using Electron (a lightweight experimental alternative to Electron) and Web Windows. Blazor has been used for mobile apps, most recently to create native applications using Xamarin controls and the Blazor model. Were we to see the beginning of a unified UI Framework for any type of.NET application, whether it be web-based, desktop, or mobile? This is undoubtedly an exciting prospect.
You had me with "without writing one line of Javascript." But, a sensible developer might wonder whether this was jumping headlong into React's juggernaut. Microsoft's track record in modern web technologies could make comparisons of the two stacks unfavorable. Blazor, which can run WebAssembly in the browser, should be a promising future. We decided to check it out and find out how it worked. This post will ensure that Blazor adheres to the standard requirements for developing web apps.
What can you expect as an experienced web developer?
- Strong Visual Studio integration. This is, after all, the shining star of the.NET company agent.
- HTML can be cleaned up using a template.
- Bootstrap or something similar with modular visual components.
- It is relatively easy to edit and see the results. You spend the majority of your web development time using this form of hot-reloading.
The demo looks different, but Blazor templates have already been mentioned. This is comforting. We were also using an Apple Mac, which was kindly told that it should be fine. This resulted in a csproj. Then we are directed to open it in VS Studio 2019.
A lovely HTML page with straightforward modifications. Technically, the templating is done by Razor, the server-side language for markup, hence the suffix. If you've used Rails and Sinatra before, you'll be familiar with them. HTTP queries, in this case, those requesting the website's root, can be routed.
PageTitle and SurveyPrompt are unmistakably HTML incursions, as Visual Studio demonstrates, and this is what we desire. This already addresses the question that we asked at the beginning. HTML and source code will inevitably compromise each other, but it seems reasonable. It is easy to write C# code and then pass the values from C# back to HTML. In the above example, the HTML and the code are separated.
A razor file can act as a page or a component. This shows that a CSS modularity that is unmistakably Bootstrap-like has been added. We have Layouts, Components, Pages, and Visual Studio Integration.
Blazor Server
The only option that enables models in production code for Blazor Development at this time is Blazor Server. At the.NET Conference, the Blazor Server hosting paradigm was first shown.
On top of .NET Core, this approach runs the Blazor app on the Server. The user downloads a small amount of JavaScript when they first open the program. The Server and app are connected instantly and in both directions using this file. With the use of SignalR, a user can engage with an application and then relay that activity to the Server. All UI modifications will be sent to the client to apply to the DOM after the Server has finished.
We know precisely what you are thinking. All of these interactions and constant UI updates are not performant. You will be pleasantly surprised. This is what the team found after they did some testing to see what Blazor Server could handle.
Test 1: Standard D1 instance running on Azure (3.5GB Memory; 1vCPU)
It could support over 5000 simultaneous active users with no visible performance degradation.
Test 2: Standard D3 instance (4vCPU and 14 GB Memory) on Azure
It could support over 20,000 simultaneous active users with no visible performance degradation. These experiments revealed that latency and memory are Blazor Server's main bottlenecks. Performance was affected if latency exceeded 200ms, and the scale of the application was restricted by the memory available on the Server.
Benefits of Blazor Server
- The full .NET Core Runtime is required.
- Fast development cycle.
- Small download size.
- The code is stored on the Server and not the client.
Drawbacks of Blazor Server
- It could perform better in high-latency development environments.
- There is no offline support. It would be best if you always were connected to the Server.
- Servers are under heavy resource pressure.
Use Case for Ideal
Blazor Server is a powerful tool that can be applied to a wide range of situations. However, its main niche lies in low-demand public apps or intranet applications. This current hosting model allows for a rapid development process because everything is on the Server. You don't need separate API source projects. For example, application services can be consumed directly within your components. We were initially skeptical about Blazor Server but have now been pleasantly surprised by its capabilities.
Why is Microsoft Blazor such a Flexible Product?
Understanding Blazor's architecture is a prerequisite for finding the solution to this query. Blazor separates how it renders UI changes (renderer) from how it computes them (app/component models). When compared to other UI frameworks, such as Angular and ReactJS/React Native, which can only create web-based UIs, Blazor is unique. By utilizing several renderers, Blazor may produce native mobile and web-based user interfaces.
Components must be written separately. It is not possible to use parts created for mobile renderers on web renderers. The programming architecture is unchanged. Developers will be able to use the renderer to make any UI once they are comfortable with it.
Render/Hosting Model
Blazor's app/components model, at its core, is responsible for calculating UI updates. However, you can choose different renderers to customize how the UI will be displayed and updated. These rendering models are also known as hosting models. As of the date of this article, Blazor has four different current hosting models in various development stages.
Blazor Server (Remote Renderer)
- Platform: Web
- Status: GA/Production Supported
Blazor WebAssembly (WebAssembly Renderer)
- Platform: Web
- Status: Preview (Committed Product)
Blazor Electron (Electron Renderer)
- Platform: Desktop Windows, Mac OS, and Linux
- Status: experimental (Not committed)
Mobile Blazor Bindings (Mobile Blazor Bindings Renderer)
- Platform: mobile (iOS and Android)
- Status: experimental (not committed)
Blazor Server was the only model that had been officially supported. Blazor WebAssembly was released around May 2020. This announcement could take place at Build. Microsoft still needs to be committed to the release of Blazor Electron or Mobile Blazor Bindings, which are marked as experiments.

App/Component Model
Here you can find all the non-UI-specific elements that make Blazor work. Here are the non-UI components that enable Blazor to function. This comprises Blazor's render tree as well as the single programming model, navigation, and routing.
We'll pay particular attention to the programming model. The first three hosting types that we have just discussed all share the same understanding of web standards. HTML and CSS will be used for these components. The fourth model of bindings, Mobile Blazor, needs help understanding any web standards. Applications created utilizing this hosting paradigm must use native mobile controls in their component writing.
Let's compare the renderer used by Mobile Blazor bindings and Blazor WebAssembly. You can easily see the differences, but we'd like you to concentrate on the similarities. Each sample has a section for markup and another code block. The code blocks in both models are the same. The "OnClick'' event is handled by a different handler for each instance. Both pieces use expressions for the output of the count value.
It's crucial to remember that the programming model is unchanged. This is what gives Blazor immense power. Once you understand how to program, you can make UIs for apps on any platform with a few simple adjustments. Before .NET, we were unable to accomplish this. We now understand Blazor's operation. Let's discuss Blazor WebAssembly and Blazor Server.
Blazor WebAssembly
For excellent reasons, the hosting model typically attracts the most significant attention. Direct competitors of JavaScript SPAs like Angular and VueJS include this hosting architecture. We can write our UI logic in C# rather than JavaScript, thanks to WebAssembly.
The client browser downloads a version of Mono.NET, which is compiled into WebAssembly. It also includes the application DLLs for the applications and their dependencies. The Mono runtime bootstraps once everything has been downloaded to the client's browser. It then loads and runs the DLLs of the applications.
What is the download's size? This query typically arises after hearing the previously stated rationale. Given that there is also a.NET Runtime, the size of the current preview, which is roughly 2.4 MB, is quite astounding. We are aware that this preview's size could be more stunning than that of some JavaScript Frameworks. The team anticipates having a drastically smaller framework by the time WebAssembly is launched in May of this year. The initial Blazor prototype made use of a compact.NET Runtime that was reduced to 60k WebAssembly. We predict rapid progress in major size improvements.
Blazor WebAssembly currently uses the interpreted mode for loading and running your application. This mode uses the Mono IL Interpreter to execute your applications.NET deals within the browser. Mono is the only component of the process compiled into WebAssembly. The team is looking forward to allowing developers in the future to select whether their apps or parts of apps will also be compiled into WebAssembly. This process is called AOT, or ahead-of-time compilation. This mode offers better performance but at the cost of a more significant download.
Benefits of Blazor WebAssembly
- It compiles into static files. This means that there is no requirement for a.NET Runtime on the Server.
- The client receives the work that was previously performed by the Server.
- Applications can run offline.
- The client and Server can easily share c # objects and code.
Drawbacks of Blazor WebAssembly
- Payload at the moment, a new Blazor Project, weighs around 2.4 MB. This is something the team is hoping to reduce significantly by May.
- Due to the size of downloads, devices with poor connections can experience longer initial load times. Devices with poor internet constant connections may experience delays in loading due to the size of downloads.
- Restricted runtime. The apps must operate within the sandbox of the browser and be subjected to the same restrictions in terms of security as JavaScript applications.
Use Case for Ideal Blazor WebAssembly
The goal of Blazor WebAssembly was to compete directly with contemporary JavaScript frameworks. Anyone who wants to work with one of these frameworks should consider Blazor. Applications written in Blazor WebAssembly can easily be transformed into PWAs. Even a template will be made available for download in May.
It's optional to install.NET on your Server to use Blazor WebAssembly. Blazor can be used without any problems to develop the front end if your backend is powered by a Node, PHP, or Rails server. Static files were created during the compilation of Blazor WebAssembly.

Conclusion
A second hosting model will shortly be added to the one we now have in use. We will return to the notion that all .NET applications may use Blazor as their sole UI framework. This is the path we anticipate Blazor will travel. Microsoft AI Developers can learn a single model of programming that they can apply wherever the Blazor hosting models go into production, which we don't think they will. It's a significant event.
Blazor, a programming language that can be learned once, and used anywhere, could provide clarity in the UI. Blazor is the buzzword for users.
