What Application Types does a MAUI Class Library .NET 8 work with? It sure doesn't work with ASP.NET Core 8.

[jbendler1]

The MAUI Class Library .NET 8 doesn't work with an ASP.NET Core Web Api project .NET 8.
Nor does the MAUI Class Library .NET 8 work with a Service Console .NET 8.

How to reproduce:

1. Open Visual Studio 2022 latest version
2. Create a MAUI Class Library .NET 8
3. Create an ASP.NET Core Web API .NET 8
4. Made a project reference to the MAUI Class Library .NET 8 from the ASP.NET Core Web API .NET 8
5. Notice the error for the new reference to the MAUI Class Library complains that the project is not compatible with andriod, ios, maccatalyst, and windows.

My goal is to host a SignalR app on a computer, and allow other computers to connect to the SignalR service.
This is also a huge problem since all of the docs that discuss self-hosting SignalR reference a library that is now depreciated.
But I can open another ticket for that issue.
Why didn't microsoft wait until things were running smoothly before publishing MAUI?
There is NO documentation for using it with .NET Core projects.
