I'm currently working with R# 8.0.10 and VS 2010 on a C# solution.Today i found an issue in R#'s code inspection. You can disable R# inspection results for specific code locations by adding a comment via the lightbulb menu. At least the comment for the "Unassigned private field" inspection has changed between R# 7 and R# 8 so that the warning is displayed again. I didn't check if other inspections are affected but i'm afraid it is.
I have added an issue to the error tracker (RSRP-375253) for this.
