Adding more, custom project types

[just-ero]

I frequently use @alexrp's Vezel.Zig.Sdk, which introduces the project file extensions .cproj, cxxproj, and .zigproj. As of today, it is not possible to add these projects to a solution file, because the extensions are not recognized.

Built-in project types appear to be handled in ProjectTypeTable.BuiltInTypes.cs. Would it be possible to add more project types here, or is there another way to allow them to be recognized by solution files?

If you add the project type guid directly in the project tag, it is able to recognize them

@edvilme Thanks. What project type would be fitting?

We will not add any new types to BuiltInTypes because that would break opening solutions in older versions of the parser. However the slnx format does allow custom project types to be added into the .slnx file in the <Configurations> section.

This is an example of the BuiltInTypes represented in slnx xml.

We are considering a feature where a list of custom project types could be provided to Visual Studio and get automatically included into slnx files in this manner.
