I've been noticing a pattern with ReSharper (both 4.5 and 5).
Very often (almost always) when I have solution-wide analysis turned on, and WPF code in my solution, ReSharper will mark a number of the .xaml.cs files as being broken.
When I navigate to the file, sometimes it magically updates and displays no errors, and other times I have to open other files that are not being correctly read and close them again to force resharper to correctly analyze them.
I assume it has something to do with the temporary .cs code that is generated with XAML, but does anyone know why this is actually happening, and if there is a work around? Should I just file a bug report with JetBrains? Does anyone else experience this?
