Critical Issue with ReSharper 9.1.2 in Visual Studio 2015 RTM: Workarounds and Estimates

gorohoroh

UPDATE! The behavior described below is supposedly fixed in ReSharper 9.1.3. Apologies to everyone affected, and please install the new version.

Sometimes bad releases happen, and it looks like this week’s ReSharper 9.1.2 was one of them.

What initially looked like a locale-specific problem turned out to be a universal hindrance for Visual Studio 2015 RTM users, with symptoms such as inverted keyboard input (sgnirt instead of string), disappearing caret, focus switching off the text editor, and random crashes.

We should point out that these problems only affect Visual Studio 2015 RTM users. If you are working in Visual Studio 2013, 2012 or 2010, you are not affected by this problem and you can safely continue using ReSharper 9.1.2.

Yesterday and today we have gathered symptoms and communicated with end users in this issue, and as of now, we have already applied a fix and we are testing it internally.

We will deploy an update as soon as possible this week. Meanwhile, if you are using ReSharper 9.1.2 in Visual Studio 2015 RTM and experiencing symptoms described above, here’s what you can do:

1. Go to ReSharper’s editor appearance options (ReSharper > Options > Environment > Editor > Editor Appearance) and disable Enable action bar for action indicators and show it next to the left margin.
2. Go to in ReSharper’s code analysis options (ReSharper > Options > Code Inspection > Settings) and disable Do not show Visual Studio bulb (VS action will be merged into ReSharper bulb).
3. If none of the above helps, disable ReSharper (Tools > Options > ReSharper Ultimate > Suspend Now).
4. Install ReSharper 9.1.3 as soon as it is published later this week.

We apologize for causing the problem to Visual Studio 2015 RTM users. We’ll be updating our testing infrastructure to help spot similar problems in future.
