The poster has stated that they found the answer to their question but I experienced the same error message with RC1 and the accepted answer did not resolve my issue. I see that Sven Gillis is still hunting for a solution as well so I'd like to share what solved the issue for me.

Turns out that the error can be triggered by a bug in RC1 Update 1 (and all prior versions) which occurs if the installation is being used via a windows login name that has a space in it. e.g. "Tim Smith".

I was not able to find a patch but there is a work around. Just create another user account on the machine that doesn't have a space in it (e.g. "Tim") and to use visual studio under that account. In my case this solved the issue. I can now create web projects in Visual Studio 2015 Community Edition Update 1 via the Asp.Net 5 templates and can run them via F5 and Ctl+F5 from within visual studio and I no longer receive the error.

However if I switch to the original user account on the machine that has a space in it, I still receive the error when trying to run a project generated from the same template. Same code ran from two different windows user accounts producing two very different results. I hope this helps someone else, I wasted 7 full days hunting for the solution to this issue.
