. NET error 47 storage zone provider type "Oracle. DataAccess. Client. OracleClientFactory" does not implement the IServiceProvider interface. Use the bucket provider that implements this interface ., Iserviceprovider

Problem description:

When I recently used VS2010 to connect to the ORACLE database, I suddenly reported "error 47: The storage zone provider factory type" Oracle. DataAccess. Client. OracleClientFactory "does not implement the IServiceProvider interface. Use the bucket provider that implements this interface .". The solution given above is 32-bit compilation, and NET Framework4.0, which has been followed, but is useless at all. Later, I thought it would be a problem with the referenced dll file. I looked at the dll and found that everything was complete. I tried to re-launch the new Oracle. DataAccess. dll. Finally, I opened several other projects and found that this error was reported for all projects connected to the ORACLE database. However, the project using the ACCESS database can be used, so I think it may be an ORACLE component problem.

Solution:

Reinstall the Oracle Data Access Components (ODAC) component. The reason is unknown. Maybe it's because ORACLE saw that I used ACCESS, so I'm so jealous?
