I've been evaluating the VS 2015 CTPs as they have come out, specificaly to follow ASP.NET vNext.
CTP 6 and R# 9 are not playing well together. After upgrading from CTP 5 to CTP 6, R# works fine after installation and the first time the project is opened. After saving the project R# loads but no longer provides intellsense or error maps in the scrollbar.
If I clear down all the R# and VS settings to basically a just installed state it works again until I save the solution and exit and restart CTP 6.
I know, it's pre-release software, I expect problems.
So, has anyone else seen anything like this and is there anything I can do to provide better feedback to Jetbrains so that this can get fixed by the time we get into the VS 2015 RC cycle?
