Using different versions of the same assembly in the same folder

Question

I have the following situation

Project A

 - Uses Castle Windsor v2.2
 - Uses Project B via WindsorContainer

Project B

 - Uses NHibernate
 - Uses Castle Windsor v2.1

In the bin folder of Project A I have the dll Castle.DynamicProxy2.dll v2.2 and NHibernate dlls. Now the problem is that NHibernate is dependent on Castle.DynamicProxy2.dll v2.1 which is not there. How do I resolve this situation.

Answer 1

I used the following configuration to resolve the issue.

<configuration>
    <runtime>
        <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
            <dependentAssembly>
                <assemblyIdentity name="Castle.DynamicProxy2" publicKeyToken="407dd0808d44fbdc" />
                <codeBase version="2.1.0.0" href="v2.1\Castle.DynamicProxy2.dll" />
                <codeBase version="2.2.0.0" href="v2.2\Castle.DynamicProxy2.dll" />
            </dependentAssembly>
            <dependentAssembly>
                <assemblyIdentity name="Castle.Core" publicKeyToken="407dd0808d44fbdc" />
                <codeBase version="1.1.0.0" href="v2.1\Castle.Core.dll" />
                <codeBase version="1.2.0.0" href="v2.2\Castle.Core.dll" />
            </dependentAssembly>
        </assemblyBinding>
    </runtime>
</configuration>
