Visual Studio 2017 hangs when started with DTE

Hello,

I have a simple code (below) that is using VS2017 DTE interface to start Visual Studio IDE, open a file and navigate to a line number. When I use this code with VS2015 - everything works as expected. But VS2017 freezes while trying to open a file. The main window caption shows (Not Responding). The only way out is to terminate VS2017 process. If I add Thread.Sleep(500) between Start() and Open(), then everything starts working. Is there a deadlock in VS2017 code?
