.NET Binding Redirection for Compilation

Question

I\'m getting the following error when I try and compile a utility, which uses files that have been deployed to our client.

Assembly \'*A* version 2.0.

Answer 1

If I understand you correctly, you have legacy assembly A that references specific version of assembly B. At the same time you are building utility C which uses both assemblies - A and B.

You should be able to use two different versions of the same assembly B by following steps. Not a compile time redirection, but it should work:

1. Add reference to assembly A to your project C, set SpecificVersion = true;
2. Add reference to assembly B version 1.1.39.0 to your project C, set SpecificVersion = true;
3. Create a post build event that copies version 1.1.39.0 of assembly B to project output path /bin/B_1.1.39.0/B.dll;

4. Add following binding redirects and specify custom location for assembly B with version 1.1.39.0 using codeBase element;

Now your legacy assembly A should be happy as you have version 1.1.32.0 of assembly B in your output folder. Your utility C should be happy as well as it using specific version 1.1.39.0 of assembly B and you have provided custom location where to look for it.

Hope it helps!
