.NET: Load two version of the same DLL

Question

I need to load two versions of the same DLL in order to compare their outputs. I assume that I can use AppDomains for this, but I need some guidence.

Answer 1

Here is a guide to do that:

extern alias oldVer;
extern alias newVer;

and when you compile:

csc /r:oldVer=Somepath\ClassLibrary.dll /r:newVer=AnotherPath\ClassLibrary.dll program.cs

or in Visual Studio change the "aliases" field in the property tab of your project references
