C# Visual Studio SDK: VCDirectories interface

Question

I am currently working on a Visual Studio addin in Visual Studio 2015 which will retrieve the global include/library directories relevant to a loaded Visual C++ project.

According to the Microsoft Documentation, the VCDirectories interface exists as a member of the Microsoft.VisualStudio.VCProject namespace. However, I am having trouble accessing this interface when I have a valid VCProject reference in scope.

public List<string> IncludeDirectories()
{
  List<string> includeDirs = new List<string>();

  // assume VCProj() returns a valid VCProject object
  VCProject proj = VCProj();
  VCDirectories dirs = proj.VCDirectories;

  return includeDirs;
}

From my understanding of the documentation, I should be able to reference the VCDirectories via proj in the snippet above. But the VCDirectories interface does not exist.

The full error reported by Visual Studio is; 'VCProject' does not contain a definition for 'VCDirectories' and no extension method 'VCDirectories' accepting a first argument of type 'VCProject' could be found (are you missing a using directive or an assembly reference?).

Can someone show me where I am going wrong?

Cheers

Edit

To complete the function above using information provided by Carlos;

public List<string> IncludeDirectories()
{
  List<string> includeDirs = new List<string>();

  // assume VCProj() returns a valid VCProject object
  VCProject proj = VCProj();
  VCPlatform pf = proj.ActiveConfiguration.Platform;
  string[] directories = pf.Evalualte(pf.IncludeDirectories).split(';');

  foreach(string dir in directories) {
    if(dir != "") {
      includeDirs.Add(dir);
    }
  }

  return includeDirs;
}

You may want to use instead the following properties:

• VCPlatform.IncludeDirectories

• VCPlatform.LibraryDirectories

• VCCLCompilerTool.AdditionalIncludeDirectories

You can get the VCPlatform as I shown in the approach of this article some years ago:

You can get the VCCLCompilerTool with the approach of this other article:
