ODP.NET : NLS datafile or invalid environment issue

I've being using ODP.NET Oracle 11g ODAC 11.1.0.5.10 Beta, which provides a new OracleProfileProvider to connect to the Oracle server.

But, I had to solve the following issue to make it work with my code.

"ORA-12705:Cannot access NLS datafile or invalid environment specified"

To solve this, you need to change the following registrty entries to point to your ODP.NET installation.

[HKEY_LOCAL_MACHINE\SOFTWARE\ORACLE]
"ORACLE_HOME"="C:\oracle\product\11.1.0\client_1"
"ORACLE_HOME_NAME"="OraODAC11g_home1"
"ORACLE_GROUP_NAME"="Oracle - OraODAC11g_home1"

Also make sure you delete the "NLS" registry key.

This new version of ODP.NET includes following features for ASP.NET,

1. Membership Provider: Stores and retrieves registered user information in the Oracle database
2. Role Provider: Stores and retrieves user role information in the Oracle database
3. Site Map Provider: Stores and retrieves site map information in the Oracle database
4. Session State Provider: Stores and retrieves session state information in the Oracle database
5. Profile Provider: Stores and retrieves user profile information in the Oracle database
6. Web Events Provider: Stores and retrieves ASP.NET health monitoring event information in the Oracle database
7. Web Parts Personalization Provider: Stores and retrieves personalization data in the Oracle database
8. Cache Dependency Provider: Automatically invalidates ASP.NET cached data based on changes made to the base data in the Oracle database

This explains the full feature list.
