C# Class and Oracle Mapping Parameters

Question

I have a type declared in an Oracle Database:
CREATE OR REPLACE TYPE t_project_code_changes AS TABLE OF obj_project_code_change;
I map to this type in C# like so
[OracleCustomTypeMapping("DEV_SCHEMA.OBJ_PROJECT_CODE_CHANGE")]
class ...
The above code works without error, however if I remove the schema name 'DEV_SCHEMA' from the attribute, it fails:
[OracleCustomTypeMapping("OBJ_PROJECT_CODE_CHANGE")]
class ...
Generates the following error:
Unhandled Exception: System.InvalidOperationException: Custom type mapping for 'ProjectCodeChangeDTO' is not specified or is in valid.
at Oracle.DataAccess.Types.OracleUdt.GetUdtName(String customTypeName, String dataSource)
At some point I will want to ship the code past 'DEV_SCHEMA', but this will result in the code failing.
The schema name comes from the connection string User Id:
"Data Source=DBNAME;User id=DEV_SCHEMA;Password=pwd;Pooling=False;"
Is there anything I can do onm the Oracle of C# side to help me with this. I.e., somehow:
1. Pass the schema name as the attribute parameter
2. Define the type in Oracle in a way that I don't need to use the schema
As a further bit of information, this problem presents itself when I use the ODP.NET client version 11.1.0.7. The 11.2 version of the DLL works perfectly without the schema name in the attribute.
Any help would be much appreciated.

What is the actual statement you're executing in the System.Data.OracleClient code? The one you've pasted right underneath SQL:? And that's exactly how you're executing it? No bind variables, etc? Just a hard coded literal statement and that's it?
Are you sure you're connecting as the same schema when you execute the same statement via Toad? I see ora-942 in the error stack, which is frequently a permissions issue. You're connected as MitSchema in both cases?
Can you reproduce this with a small test app that does nothing but execute that statement, similar to the code in this post for example?
Performance issue with ODP.NET 11.1.0.7.20
System.Data.OracleClient is generally supported by Microsoft rather than Oracle if the behavior is specific to their provider. Do you see the same behavior when using Oracle's data provider? If so, it may be more appropriate to post this in the ODP.NET forum ( ODP.NET ), as this forms is specifically for the Oracle Developer Tools for Visual Studio
Hope it helps,
