I have a question about server side rendering of Blazor web app.

Question

Hi, I am a GUI application developer.

Our company is using Blazor web app.

We are enthusiastic about using the attractive framework you provide and would like to ask some question.

Does the code block (@code) created in the .razor file work by creating as many threads as the number of clients connected to the server?

Hi john yoon, 

Thank you for reaching out to Microsoft Q & A forum. 

No, the @code block in a .razor file does not create a separate thread for each client. In Blazor Server, all client interactions are handled on the server through a SignalR connection, with each connection running in a single-threaded context. The framework manages thread safety using the ASP.NET Core synchronization context. For resource-intensive tasks, it's best to use Task.Run or async methods to improve performance and scalability.
