Issues in Visual Studio errors detection

I installed VS 2013 and CUDA Toolkit 7.5. Everything is fine, but Visual Studio detects a lot of errors.
What is strange, that I can run this projects with no problem(CUDA sample projects). This is what I mean:

You’re running into intellisense. This is a topic that has been covered extensively both here on the devtalk forums and elsewhere. Try a google search, for example “cuda intellisense” or “cuda red underline”

Intellisense can get tripped up by the CUDA syntax, some of which is non-standard. If your application compiles correctly, where intellisense said there was an error, then in fact intellisense is usually wrong (confused.)

Thank you very much.
