Announcement: "Package Load Failure" error with ODT and Visual Studio 2005

This seems to be caused by an assembly mismatch issue. The Oracle.DataAccess.dll version on your machine is 1.102.2.20 whereas it should be 2.102.2.20. You can try a couple of things to see if it resolves the issue on your machine.
1. Execute the following command from a command prompt:
gacutil /i <Oracle Home>\odp.net\bin\2.x\Oracle.DataAccess.dll
where <Oracle Home> is the Oracle Home directory where you installed ODT 2005. For example, <Oracle Home> on my machine is c:\oracle\product\10.2.0\client_1.
OR
2. Deinstall ODP.NET 1.x from your machine (if you're not using it) and install ODP.NET 2.0 in the same Oracle Home.

大概的问题是：
ODP.NET 默认将 for .net 1.x 也安装了，导致 .net 2.0 无法加载正确版本的程序集，
解决：
重新安装 ODP.NET，如果只有 VS2005，去掉 for .net 1.x 的组件：
如下图，需要注意的，先要取消第三个复选框（Oracle Developer Tools for ... 20003）才可以取消第一个复选框（Oracle Data Provider for .NET 1.x ...）
