To everybody who is interested in this problem. One of ReSharper users had a conversation with guys at Whole Tomato and here's what they said:
"Unfortunately, Resharper and VA X cannot live inside the IDE at the same time. We see this as a problem for mixed C++/C# developers and intend to add an option to our product so it disables itself for C#.
We expect the fix in the next few builds."
