There are known limitations to Microsoft Entity Framework support for
the IBM® Data Server Provider for .NET.
The following limitations apply:
- General limitations:
- Only database-first scenarios are supported: any
database object that you reference in Entity Framework must first
exist in the database.
- Invocation of store-specific functions is not supported.
- Trusted context connection properties that you set in the Server
Explorer Add Connection dialog are not passed to Entity
Framework connections.
- DB2® for z/OS® server-specific
limitations:
- Data type REAL is not supported. Applications must either use
the FLOAT data type in the schema of the table or specify the type
as FLOAT in the client schema (entity data model) even if the type
on the server is REAL.
- Informix Dynamic Servers
- Server-side
pagination is not supported.
For information about Entity Framework limitations that
are associated with updating the database model, see the troubleshooting technote.
