Blazor Server and .NET 10

[daver77]

Hi,

I have a strange issue with v1.0+ and Blazor Server. My site works fine on v0.24 with Blazor Server on .NET 10. When I try to update to v1.2 I get the following 'Error: Circuit has been shut down due to error.' in the console, I can't seem to find the error even with detailed errors enabled

Even if I comment out 'app.UseSecurityHeaders' from program.cs, therefore removing my CSP, I still get the error. If I rollback to 0.24 it works fine again.

I have v1.2 working fine in non Blazor Server sites

It's very odd, I can't see how just adding a reference can cause this even when not in use

Agreed, there's basically no mechanism that would cause this alone I think 🤔 So I think there must be something else going on here - are you literally only using the UseSecurityHeaders() call, or do you have calls elsewhere for grabbing a generated nonce in your components for example?

Or to put it another way, if you comment out app.UseSecurityHeaders and remove the reference entirely does the app still compile? And does the circuit work in that case?
