Before you start

If you have not already done so, make sure your Visual Studio copy is set up to work with an Unreal Engine project — here are detailed instructions in the Unreal Engine documentation.

At the very least we recommend that you disable Visual Studio squiggles as they often produce false positives in Unreal Engine projects — go to Tools | Options | C++ | Advanced | Code Analysis and set Disable Squiggles or Disable C++ Code Analysis Experience to True.
