What steps will reproduce the problem? 1.Add reference to Moq.dll from "NET40" 2.Add reference to Castle.Windsor.dll 3.Add reference to Castle.Core.dll (which is required by Windsor) 4.Try use method "Castle.DynamicProxy.Generators.AttributesToAvoidReplicating.Add(...)"

What is the expected output? What do you see instead? Project must compile, but I see compile time error 'Castle.DynamicProxy.Generators.AttributesToAvoidReplicating' exists in both '...\Windsor\dotNet40\Castle.Core.dll' and '...\MoQ\NET40\Moq.dll'

If I use Moq.dll from "NET40-RequiresCastle" folder, which is logically in my situation, I got versions conflict - Moq.dll uses Castle.Core, Version=2.5.0.0, but Windsor uses Castle.Core, Version=2.5.1.0

What version of the product are you using? On what operating system? Moq.4.0.10827.Final.zip is used on Windows7

Please provide any additional information below.

Use the Moq.dll that is inside the "NoCastle" folder, so you can use your own version of it.

As long as it's binary compatible with what Moq has been compiled, you'll be fine. Worst case, you'll have to add a runtime binding redirect.

You'll need to use standard .NET binding redirect for the version fix.
