Visual Studio Extension: Compile file with VCFileConfiguration fails

I am writing a simple C# Visual Studio extension in which I need to compile C++ files with the current project configuration. I tried to use VCFileConfiguration.Compile for this task. It works fine if I set the waitOnBuild parameter to false. If I set it true to achieve a blocking call, I get a Microsoft.VisualStudio.ProjectSystem.ProjectException exception, no matter if the file can be compiled without errors or not.

Is this a bug or is there anything special I need to setup?

My code so far (stripped error handling):

var projectItem = dte.ActiveDocument.ProjectItem;
var project = projectItem.ContainingProject;
VCProject vcProject = (VCProject)project.Object;
VCConfiguration activeConfiguration = vcProject.ActiveConfiguration;

VCFile vcFile = projectItem.Object as VCFile;
IVCCollection fileConfigCollection = vcFile.FileConfigurations;
VCFileConfiguration fileConfig = fileConfigCollection.Item(activeConfiguration.Name);
try
{
    fileConfig.Compile(false, true);
}
catch (Microsoft.VisualStudio.ProjectSystem.ProjectException exception)
{
    // Fails all the time if waitOnBuild == true
}

The exception in Detail:

I was able to take a glimpse of the internal code: Both options are explicitly deprecated and the error is filed as a documentation/api bug.

First: Try Restarting Visual Studio and your computer - this is the most common solution for your problem.

If the above doesn't help: Try to clean the solution and remove "vspscc" and "vssscc" files, and then restart VS and "Rebuild All".

Final option: In Visual Studio "

Tools / Options / Projects and Solutions / Build and Run setting area: Try to change

"MSBuild project build output verbosity" to "Diagnostic"

so you can determine what is failing in your project.
