ODAC 10.20221 visual studio integration

I've downloaded ODAC1020221.exe from oracle website. It installed 10g client but neither VS2008 nor VS2010 sees ODAC provider. Oracle client 11 doesn't work with our oracle server (9.1 version), but just for the sake of test I've tried to install it and visual studio sees ODP.NET fine. ODP.NET 开发者_StackOverflow10 supports only 1 and 2 framework? VS2008 and 2010 do not see ODP.NET 10 because of that?

Odac is only compatible with 10g and up
