How to support MSE4 and MSE5 in mixed mode in the same project.

C#3.5

Hi All ,

Can we use MSE4 and MSE5 in mixed mode in the same project.
MSE(Microsoft Enterprise Library)

In our project we are currently using MSE4 and would like to upgrade to MSE5.
Our project contains interfaces that use ref and out keywords.
But MSE5 does not support ref and key words.

But our requirement is we need to support legacy /old clients that use MSE4 and interfaces that use ref and out keyword.

Is it possible to support multiple interfaces so that we can use MSE4 and MSE5 in the same config file so that it can use the version as we required.basically MSE4.0 should invoke for legacy code and MSE5.0 for the latest code.


Please let me know your ideas / suggestions on that.

Thanks,
Sudhakar
