Radzen Blazor Studio Debugger

I tried to use a debugger in program.cs (made a breakpoint) but nothing happened, then I tried in one of the pages and it works.

Is it expected behaviour?

Yes, for the time being this isn't supported. Radzen Blazor Studio attaches to a running process and it is too late at that point to break on a breakpoint in Program.cs

Thank you very much, Atanas
