AutoCAD freezes on DocumentManager.Open() when debugging in Visual Studio

[ottosson_mathias]

I want to open a file in the editor. But for some reason AutoCAD freezes on file open when debugging in Visual Studio. If I do not run the command while debugging it works just fine!

[CommandMethod("MyCommand", CommandFlags.Session)]
public void OpenFile()
{
    // ...

    Application.DocumentManager.Open(filePath, false);
    var x = "hello world"; // Never happens when debugging!

    // ...
}

Does anybody know how I can fix this issue?

Thanks!
