Help me with this error:
Error CS1069
The type name 'SqlConnection' could not be found in the namespace 'System.Data.SqlClient'. This type has been forwarded to assembly 'System.Data.SqlClient, Version=0.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' Consider adding a reference to that assembly. QLSV C:\Users\thais\Desktop\Winform\QLSV\Program.cs
At the first time I did this project, it did smoothly like a butter but after that the error occurred.
I've already tried to delete and re-install VS 2022 again, try to pick another kind of project, but it's still luck getting rid of the error.
