Problem moving EF Model from VS 2008 to VS 2010

Post by Anchor » Tue 02 Aug 2011 04:48


Recently I upgraded my project that uses dotConnect for Oracle to model a DB schema from VS 2008 to VS 2010. Things seemed to be going fine until I tried to call a modeled stored procedure that returns an entity. When I do I get the following error...

"The type of the key field is expected to be 'System.Int64', but the value provided is actually of type 'System.String'."

The field in question is a "USER_ID" field that when modeled (and shown in the Mapping Table in VS 2010) is defined as an Int64 and models a column in the DB that is a NUMBER(15).

My DLL used dotConnect for Oravle and the Entity Framework and was built using VS 2008. And it still works fine in VS 2008 but after moving it to VS 2010 I get the above error.

Can someone please tell me what could be causing the problem?

We cannot reproduce the problem at the moment.

As we understood, you have also changed the target framework from 3.5 to 4.0 (EFv1 -> EFv4). Is this correct? Anyway, this should work. Please send us a small test project with your model and the DDL/DML script.
