Could this cause problems or something we need to solve?

No, this won't cause any problems. AMP5 pre-dates the release of .NET 4 so it operates in a compatibility mode. .NET 4 just produces a warning message to let you know that this is happening. The main change in .NET 4 that affects the profilers functionality is that the layout of string objects has been changed, so version 5 of the profiler is unable to display their values.

Version 6 of the profiler has been updated to fully support the new .NET 4 profiling interface.
