• ReSharper 3.0 Beta - I'm not a real big beta fan so I'm holding off on taking this bad boy for a spin.  However, Joey and JP both give great praises to the early versions.  Most notably, solution wide error analysis.
• Improve Your Programming Experience in Visual Studio - A nice short review of ReSharper by Scott Mitchell.
• Replace standard VS refactoring menus with ReSharper - The context menu in VS can get pretty hairy.  If you don't use the VS refactoring you can have ReSharper replace them.  Menu ->Resharper -> Options -> General -> Replace Visual Studio menu items by respective ReSharper ones.
• VstsUnit Plugin for ReSharper - On my current project we're using Visual Studio Team System and cannot use the NUnit framework.  This is a nice plugin but I've found myself just using the Test View window and Ctl+Shft+X to run the current test.  Side note - there is just something wrong with a context menu items that says “Create Unit Tests“.  If you write your tests first, what use does this have?  :-)

Currently, the 3 commands I find myself using the most are F12, Ctl+Alt+F7, and Ctl+e.

• F12, along with Shift+F12 will navigate to the next and previous errors in the code.  Combine that with Alt+Enter and you can fix your errors in no time flat...without spending time on a compile.
• Ctl+Alt+F7 provides a quick list of "usages" for a specific item.  Place the caret on the item and there you go.

• Ctl+e provides a list of recent files.

At some point, I introduce or talk about ReSharper with most every developer I work with.  If they had a referral program I be doing pretty good. :-)

Giddy Up!
