Frequently Asked Questions about Blazor-wasm
What is Blazor-wasm?
Blazor WebAssembly (WASM) is a client-side web framework from Microsoft that allows developers to build interactive web applications using C# and .NET instead of JavaScript. Applications run directly in the browser via WebAssembly.
What are the primary use cases for Blazor-wasm?
Interactive single-page applications (SPAs) with C#. Line-of-business applications requiring .NET libraries. Client-side applications with offline capabilities. Web apps needing tight integration with ASP.NET Core backends. Modern web UI replacement for WinForms/WPF apps
What are the strengths of Blazor-wasm?
Leverages existing .NET skills and libraries. C# code runs natively in the browser via WebAssembly. Component reuse between server-side and client-side Blazor. Strong Microsoft tooling support (Visual Studio, CLI, debugging). Secure execution sandboxed in the browser
What are the limitations of Blazor-wasm?
Initial download size can be large compared to JS frameworks. Browser compatibility depends on WebAssembly support (modern browsers only). SEO is challenging without prerendering. Limited ecosystem compared to JavaScript frameworks. Client-side execution may not be ideal for CPU-intensive tasks
