After upgrade to VS 2015 CTP5 began to appear an error when starting an asp vNext project: clip2net.com/s/3dqDMNm
Reinstall to another drive and CTP6 does not work, same warning appears when you run the project/open the html(and probably js) files.
Stackoverflow on Google a few such errors, however, these fixes do not help(reset the cache package'her devenv /setup /rebuild, etc.).
In what could be the error and what are possible fixes?
