RPC_E_SERVERCALL_RETRYLATER Visuak 2015

I created an application that generates WCF, creates a visual studio instance and generates the solution automatically.

Visual Studio 2012 works perfectly, the problem is when visual studio is installed in its 2015 version.

If I put breakpoints everywhere, it generates everything correctly, but if I start it without interruption points it starts to burst and it is not always at the same point.

Throw the error:

  

"The message filter indicated that the application is busy. (Exception from HRESULT: 0x8001010A (RPC_E_SERVERCALL_RETRYLATER))"

and I do not know how to solve it.

I leave you a piece of code. It is usually burst in the for, moments where the application does not give time to finish another thread.

            if (pathnametlb.ToUpper().Contains(".EXE"))

            //Visual Studio 2015
            if (type == null)
                type = System.Type.GetTypeFromProgID("VisualStudio.DTE.14.0");
