Visual C++ project and properties

[Agrael1]

Hello, I'm working on extension for C++ include management. Right now I have to use Com interfaces which have little to no documentation. Will there be a port of VCProject compiler and properties?

I've never worked with C++ from a extensibility perspective, so I'm not sure what is involved in doing so

The most common things queried in our project is compiler options. That requires several queries: DTE->Project as VCProject->IVCRulePropertyStorage2 | VCCLCompilerTool which are quire cumbersome. As of now I could not find any converters from VS.Solution.GetActiveProjectAsync() to VCProject neither are there any guides on how to get project property page values.

Also, is there any command to save al current files, without querying them?

You can convert a Community.VisualStudio.Toolkit.Project to a VCProject like this:

private const int ExtObject = (int)__VSHPROPID.VSHPROPID_ExtObject;
public static async Task<VCProject?> ConvertToVcProjectAsync(Community.VisualStudio.Toolkit.Project? project)
{
    if (project == null)
        return null;

    await ThreadHelper.JoinableTaskFactory.SwitchToMainThreadAsync();

    project.GetItemInfo(out var hierarchy, out _, out _);
    if (hierarchy.GetProperty(VSConstants.VSITEMID_ROOT, ExtObject, out var obj) != 0)
        return null;

    return (obj as EnvDTE.Project)?.Object as VCProject;
}
