while upgrading to .NET Framework version 4.0 to 4.8, the designer files for dataset .XSD files are removed and when on right click the xsd file --> Run Custom Tool throws a popup window with the error message "Error101 Failed to generate code. Exception of type 'System.Data.Design.InternalException' was thrown". Also tried to connect to Oracle DB connection from server explorer but was not able to connect to Oracle DB.
Any support is greatly appreciated!!
