The selected connection uses an unsupported database provider

 

For the latest documentation on Visual Studio 2017, see The selected connection uses an unsupported database provider on docs.microsoft.com. This message appears when you drag items that do not use the .NET Framework Data Provider for SQL Server from Server Explorer/Database Explorer onto the LINQ to SQL Tools in Visual Studio.

The O/R Designer supports only data connections that use the .NET Framework Provider for SQL Server. Only connections to Microsoft SQL Server or Microsoft SQL Server Database File are valid.

To correct this error

  • Add only items from data connections that use the .NET Framework Data Provider for SQL Server to the O/R Designer.
