I am following the 'SignalR with Blazor WebAssembly' tutorial: https://docs.microsoft.com/en-us/aspnet/core/tutorials/signalr-blazor-webassembly?view=aspnetcore-3.1&tabs=visual-studio

However, I get an exception when running my Blazor application:

Repro can be found here: https://github.com/ChristianWeyer/blazor-signalr-repro

Any idea what could be the issue? .cc @danroth27

Try a full clean and rebuild of the project.

Probably a dupe of https://github.com/dotnet/aspnetcore/issues/18721 which is fixed by https://github.com/dotnet/aspnetcore/pull/18832

Hi @BrennanConroy - thanks for the super-quick reply :-)

That was easy. Cool.

Do you mind explaining what happened?
