We are a .NET Blazor WebAssembly Company based in the United Kingdom

Blazor WebAssembly FAQs

Assemblysoft is a Blazor development company, with real-world experience delivering Blazor WebAssembly applications, based in the United Kingdom. Blazor WebAssembly is not just another service that we offer, it is what we specialise in, day in, day out.

We have completed numerous Blazor WebAssembly projects for our clients, and know how to get the best out of the Blazor framework and .NET ecosystem. We know what works and what doesn't and our expert team know how to deliver clean code following best practice.

As with many technology choices, especially those that will affect your future business goals, the answer is, "It depends". We know that initial answer can be a little infuriating at first but we need to ensure we offer you the best value for the success of your business. An initial consultation with us will often clearly identify the best fit. We are positive it is Blazor, but there are a number of options to ensure delivery of the best product that you want to build.

Assemblysoft is an expert Blazor development company, and knows how to get the best out of all the hosting models and rendering modes. Starting with .NET 8, we are able to future proof your Blazor hosting model decision by getting the best out of both Blazor Server, Blazor WebAssembly and Static Server Rendering. Talk to us to find out more, we love talking about Blazor!

Blazor has two hosting models, client-side and server-side. For client-side Blazor application execution, Blazor depends on WebAssembly (WASM).

Blazor WebAssembly (WASM) can execute client-side C# code directly in the browser.

A Blazor application, its dependencies, and the .NET runtime are all downloaded to the user's browser.

The application is directly executed by the UI thread of the browser. The same process is used to handle events and update the User Interface (UI).

While .NET runs on WebAssembly, we can reuse the code and libraries from the server-side parts of the application.

1. Offline mode

It can run in offline mode, which means a server connection is not necessary.

2. .NET running directly in the browser

Because a mobile version of the .NET runtime comes as part of the application, we are able to directly run .NET code in a browser.

3. Performance

Compiled C# code runs and executes faster than Javascript, providing a great user experience for your end users.

4. Code reuse

Both the client and the server can use the same validation code.

1. Initial load times

Initial load times are longer because it downloads all the files to the client.

2. Limited .NET tooling and debugging capacity.

Blazor WebAssembly, a framework enabling developers to build interactive web applications with C# and .NET, has some limitations in terms of .NET tooling and debugging capacity. This primarily stems from the nature of WebAssembly and the current state of tooling support for .NET in this context.

1: WebAssembly Constraints: WebAssembly is a binary instruction format designed for stack-based virtual machines, primarily used within web browsers. It's sandboxed and operates in a constrained environment, which inherently limits the range of tools and debugging capabilities that can be directly applied, compared to a traditional .NET runtime environment.

2: Client-Side Execution: Blazor WebAssembly apps run client-side in the browser, which is a different environment from the server-side .NET runtime. This difference implies that certain .NET tools and profilers, which are designed for server-side diagnostics and debugging, are not directly applicable or need to be significantly adapted for client-side environments.

3: Debugging Support: While Blazor WebAssembly supports debugging in browsers through WebAssembly debugging extensions, the experience is not as seamless or feature-rich as traditional .NET debugging. For instance, inspecting variables, evaluating expressions, and performing certain debugging tasks can be more challenging and less intuitive compared to server-side .NET applications.

4: Tooling Evolution: The tooling for Blazor WebAssembly is still evolving. As a relatively new technology, it hasn't yet achieved the same level of maturity in terms of comprehensive tooling and debugging support seen in more established .NET environments. This is an area of active development, and improvements are continuously being made.

5: Dependency on Browser Tools: Blazor WebAssembly development often requires reliance on browser developer tools for debugging. While these tools are powerful, they are primarily designed for JavaScript and Web technologies, not specifically for .NET. This can lead to a learning curve and limitations in .NET-specific debugging capabilities.

For us at Assemblysoft, specialising in Blazor and Azure, these limitations mean that while developing with Blazor WebAssembly, a different approach and additional considerations are needed compared to traditional .NET development. Emphasising expertise in navigating these unique challenges and offering solutions that leverage the strengths of Blazor WebAssembly, while mitigating its limitations, can be a significant value addition to clients.
