ReSharper does analyze the source code and provides its own Code Suggestions, which are not binded to the VS warnings. If you think that ReSharper has a false positive warning in your case, please:
1. Feel free to lower the Inspection Severity of the particular Code Inspection in the "ReSharper | Options | Code Inspection | Inspection Severity" dialog to not be bothered by it.
2. Provide us a small sample solution, which will demonstrate the issue. We will check it out and, if it is a false positive there, provide a bugfix for this in the next ReSharper version.
We apologize for the inconveneince.
