In beta 8 I often get this error:
---------------------------
Microsoft Visual Studio
---------------------------
The following error occurred attempting to run the DNX design time process (dnx-clr-win-x86.1.0.0-beta8).
No connection could be made because the target machine actively refused it [::ffff:127.0.0.1]:49724
The DNX design time process provides intellisense, build, and reference information to Visual Studio and without it your experience will be very limited. Please try closing and reopening Visual Studio to see if that corrects the problem. Alternatively, check
that the DNX version is properly installed or try changing to a different installed DNX version using the project property pages.
---------------------------
OK
---------------------------
Restarting VS usually solves the problem.
What might be th reason for this error and how to fix it?
