How to change the highlighting color for ASP.NET components in ReSharper

Background/Situation

When using the CreatedAtAction method in an ASP.NET Core Controller, the method is highlighted in red by ReSharper as if there was an error despite the code compiling and functioning correctly. However, Visual Studio itself does not display an error message, and when ReSharper is suspended, the highlighting disappears completely.
