Is it possible to create a code-first Entity Framework model that connects to an existing database using ODP.Net without having any settings in the app.config file?
I have tried many different things.
Currently I am setting DbConfiguration:
sealed class EntityFrameworkConfiguration : DbConfiguration
{
public static readonly DbConfiguration Instance = new EntityFrameworkConfiguration();
EntityFrameworkConfiguration()
{
this.SetDefaultConnectionFactory(new OracleConnectionFactory());
this.SetProviderServices("Oracle.ManagedDataAccess.Client", EFOracleProviderServices.Instance);
}
}
DbConfiguration.SetConfiguration(EntityFrameworkConfiguration.Instance);
I am passing an OracleConnection
directly into the EF context.
However, I either have problems with the SQL being generated in SQL Server format (using double-quotes around table aliases), or I get the following error:
An unhandled exception of type 'System.NotSupportedException' occurred in EntityFramework.dll
Additional information: Unable to determine the provider name for provider factory of type 'Oracle.ManagedDataAccess.Client.OracleClientFactory'. Make sure that the ADO.NET provider is installed or registered in the application config.
Has anyone any experience of getting this to work without polluting app.config with crud?
Uff. Found the problem.
Because I was registering column mapping using lower case the query didn't work. The column and table names must be in upper-case.
How silly.
