ODP.Net 1.1 client doesnot work on machine with oracle 11g

I have created an application that uses Oracle.Dataaccess library version 1.10. When开发者_C百科 I deploy the application on a machine that has 11g client i.e. Oracle.Dataaccess library 2.0 then this does not work. I get a message "Cannot find library Oracle.Dataaccess ver 1.10"

I am not sure what is wrong. Can anyone help ?

When using signed .NET assemblies, the correct version to use is essential. If you need to access Assembly version y with an assembly compiled against version x, use an Assembly redirect.
