Question
I'm getting the following warning message...
Return type of function 'ConnectionNew' is not CLS-compliant.
...for this function:
Public Function ConnectionNew(ByVal DataBaseName As String) As MySqlConnection
Dim connection As MySqlConnection = Nothing
connection = getConnection(DataBaseName())
Return connection
End Function
What does this message mean, and how can I fix it?
Solution
It is because you are returning an object of a type that's not CLS compliant. Nothing you can do about that, you didn't write the type. Just acknowledge that you know that it isn't compliant, it isn't otherwise likely to cause any problems. Unless you use the function in another language that doesn't support all the .NET types. Fix:
<CLSCompliant(False)> _
Public Function ConnectionNew(ByVal DataBaseName As String) As MySqlConnection
'' etc...
End Function
