Here is the code to test with. Create a new Form, add a button and put this code in the button.
Dim dbf As Data.Common.DbProviderFactory
'
' uncomment one of the below dbf =
'
'this fails
'dbf = Data.Common.DbProviderFactories.GetFactory("System.Data.SqlClient")
'these work
'dbf = Data.Common.DbProviderFactories.GetFactory("System.Data.Odbc")
'dbf = Data.Common.DbProviderFactories.GetFactory("System.Data.OleDb")
Dim conn As Data.Common.DbConnection
conn = dbf.CreateConnection
The create connection only fails for SqlClient. The error is
System.TypeInitializationException was unhandled
HResult=-2146233036
Message=The type initializer for 'System.Data.SqlClient.SqlConnection' threw an exception.
