Did anybody get resharper 4.5 working on V2010 ?
Wait few days and try ReSharper for VS2010 - http://blogs.jetbrains.com/dotnet/2009/05/preview-of-resharper-for-visual-studio-2010-coming-soon/
Check out this:
Scientists hypothesize on existence of ReSharper for Visual Studio 2010. They argue pros and cons endlessly, bringing history to the table and even gamble around the odds if ReSharper can run in the new shining Visual Studio 2010 Beta 1.
You can know for sure, it runs! Want to know when it will be running for you? Read on!
Both of your answers are still wrong, he asked did you get R# 4.5 working... which the answer is NO. Visual Studio 2010 has a bran spanking new Text Editor written in WPF and MEF, so I very much doubt that R# 4.5 will support that :P
You can find ReSharper for Visual Studio 2010 Preview at the address below http://www.jetbrains.net/confluence/display/ReSharper/ReSharper+for+Visual+Studio+2010+%28Preview%29
they have an interview with the resharper lead developer on http://www.how-to-code.com/ - apprantly you'll have to wait for resharper 5
