Adding RevitAPI.dll into a Visual Studio

When I’m adding a RevitAPI.dll file into Visual Studio this message has appeared (The selected component could not be browsed) anyone could support me?

Answer

Have you manually navigated to the directory containing Revit.exe and selected the Revit API .NET assembly there?

Have you set the correct version of the .NET framework?

Revit 2021 requires .NET 4.8.

If both answers are yes, your system may be corrupted.
