Error CS8801: Cannot use local variable or local function 'builder' declared in a top-level statement in this context

Radzen Blazor Studio

I only get this error in Radzen Blazor Studio. Any ideas…?

Nothing changed in my .csproj nor Program.cs. I’ve Cleaned and Rebuilt the solution multiple times. I’ve restarted Blazor Studio multiple times and ran the analyzer that reports the same error. Seems like another temp location needs to be cleared…?

I found the problem. I did add a variable like this…

var baseUri = builder.HostEnvironment.BaseAddress;
builder.Services.AddTransient(sp => new HttpClient { BaseAddress = new Uri(baseUri) });

I changed it back to this, and it compiled in RBS…

//var baseUri = builder.HostEnvironment.BaseAddress;
builder.Services.AddTransient(sp => new HttpClient { BaseAddress = new Uri(builder.HostEnvironment.BaseAddress) });
