What is Blazor WebAssembly?

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

How does it work?

• 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 browser. • The application is directly executed by the UI thread of the browser. The same process is used to handle events and update the UI. • While .NET runs on WebAssembly, we can reuse the code and libraries from the server-side parts of the application.


• It can run in offline mode, which means a server connection is not necessary. • Directly run .NET code in a browser. • Quicker than JavaScript. • Both the client and the server can use the same validation code.


• Limited .NET tooling and debugging capacity. • Loading times are longer because it downloads all the files to the client.
