Assembly version mis-match

I 开发者_开发百科am creating an application using NServiceBus version 2.0.0.1219 and I need to reference another assembly created by someone else (old assembly), but that assembly references NServiceBus version 2.0.0.1071 which leads to a failure to execute in my application.

How can i let the "old assembly" know I have version 2.0.0.1219 of NServiceBus, it can use this instead of version 2.0.0.1071?

Could not load file or assembly 'NServiceBus, Version=2.0.0.1071, Culture=neutral, PublicKeyToken=9fc386479f8a226c
