How to handle application with 3rd party dll reference

Question

I am writing a c# WinForms application. I reference a 3rd Party dll (SDK) to perform specific tasks. I expect this dll to be installed on clients machine.

Now, if I use say Version 1 as reference , and client has Version 1 installed. The application works.

Later, if the client has upgraded to Version 2, my application wont work because, there is no more Version 1 dll.

How do I code my application? One for each version of the 3rd party dll? or is there a better way? (SDK is backward compatible)

You can add an assembly binding redirect to app.config. Something like this:

<dependentAssembly>
    <assemblyIdentity name="someAssembly"
      publicKeyToken="32ab4ba45e0a69a1"
      culture="en-us" />

    <bindingRedirect oldVersion="7.0.0.0" newVersion="8.0.0.0" />
</dependentAssembly>
