Aspire 13.1.0 is Broken!

Somebody broke the Aspire eco system. I can build the Solution, but I cannot run it.

I came across this today in VS 2026 / Aspire 13.1 - I haven't specified <GenerateAssemblyInfo> (with either true or false) in any csproj or props files. I tried adding it manually to the AppHost csproj, but the error still occurred.

ETA: I had missed adding <Project Sdk="Aspire.AppHost.Sdk/13.0.0"> to the top of the AppHost csproj - this was a fork of older Aspire 8 project. The error is now gone
