I'm a 25-year .NET veteran, and I spent the day vibe-coding a new SDK to let you edit Documentation inside Visual Studio.
Getting it to work was a clusterf***.
It appears that there is very little documentation on how to build your own SDKs, including how to build functionality that relies on other SDKs (including NoTargets).
After dozens of iterations and failures, we finally got a version to work that imported the Microsoft.Build.NoTargets NuGet package into the file, and then copied the targets into MY NuGet package. No other permutation worked.
I've had the same problem trying to build Roslyn generators, there is very little documentation on how to build the NuGet packages when you have dependencies.
With the advent of AI, this problem can be easily solved. Please point Claude Code at the codebase and have it write better docs. It would greatly help us all. Thanks!
