Recently I've installed the Visual Studio 2013 Update 3 RC and the open .NET Compiler Platform (code name "Roslyn"), and then I found there is some problem with Resharper.
1. After install the Update 3 RC, the Resharper will not work. In the Visual Studio main menu, the "Reshaper" menu is disapper, However in the Tools / Options dialog, the Resharper menu still exists. Well, this is not a critical problem, the disaster is I cannot type in the edit window! More exactlly, all the sementic keys (like ~ ; , ( ), enter, tab, backspace, and so on) will be ignored (but alphabet keys are still functional). When I suspend Resharper, the problem will be solved temporary. I've re-installed Resharper for times but the problem never fixed.
2. The current version of Reshaper cannot support the new C# (maybe also Basic) syntax in Roslyn, e.g. primary constructor, property value initializer, etc. I think this is reasonable because Roslyn has not entered the RTM phase, but it will be better is Resharper can support the new compiler.
Thank you all for your reply :-)
