SqlDataSource seems to work fine with an Oracle DB connection string but I cannot get the EntityDataSource component to work with Oracle. Is this supported please? I do not see any document for this combination.
I set up the EntityDataSource component using the wizard and then when I click on the Preview tab the following error appears:
An error has occurred while processing Report 'Report1':
Exception has been thrown by the target of an invocation.
------------- InnerException -------------
An error occurred while getting provider information from the database. This can be caused by Entity Framework using an incorrect connection string. Check the inner exceptions for details and ensure that the connection string is correct.
------------- InnerException -------------
The provider did not return a ProviderManifestToken string.
------------- InnerException -------------
A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)
------------- InnerException -------------
The network path was not found
It seems to show a SQL rather than Oracle error!
Thanks

Hello Mark,
Generally not all of the Oracle data providers support Entity Framework. Thus first our suggestion is to check if your provider officially supports Entity Framework and try to use it with a generic control. Additionally you can try to preview the report in a report viewer to make sure the error is not due to the design time peculiarity.
