Describe the bug

I have just upgraded some of my team's Blazor project's packages from 8.0.3 to 8.0.4 and it gave this error:

I was able to streamline which package was giving that issue on my PC and found out it was Microsoft.AspNetCore.Components.WebAssembly.DevServer. The 8.0.3 version works with the other upgraded packages but the 8.0.4 version does not.

I recreated the issue with a new Blazor Wasm App and the issue still occured.

Expected Behavior

I should not be getting any error while starting off my Blazor project

Steps To Reproduce

Create a Blazor Project with the updated packages especially Microsoft.AspNetCore.Components.WebAssembly.DevServer with 8.0.4 and try to run the project.

Should give the Visual Studio Error Message

Exceptions (if any)

No response

.NET Version

dotnet 8

Anything else?

Thanks for contacting us. Can you please confirm that you've updated all your packages (and SDK) to 8.0.4? Mixing and matching those dependencies may cause unexpected behaviors.

Hi @mkArtakMSFT, I have updated all packages now and installed the SDK. That has fixed the issue.
