When MonoGame 188.8.131.523 (a hotfix) was released, the NuGet packages did not include the XML documentation file. This means no intellisense with those nice juicy descriptions as to what things do when you hover over them. Why were they not included? Oversight? Mistake? I dunno, but hey, things happen.
So, if you want to include them yourself, you would need to manually clone the git repo, update the csproj files to tell them to generate the documentation files, then build the projects to get them. But that’s a lot of work and I hear you.
So I’ve done it for you.
Since I am unable to upload XML files here on the forums, I’ve created a GitHub repo with all the steps neccessary to include the missing intellisense. You can find this at the following link
