You can sign the modified assembly and push it to the GAC, so that the applications which reference this assembly, will be unaware of the difference.

You should:
- Specify all parts of the version number, meaning in version A.B.C.D specify all parts (A, B, C and D), rather than A.B.C.* in AssemblyInfo.cs file,
- Use the same sn key.

Now version-specific references should reach the dll safe and sound.

See a wonderful CP article on the topic by Oren Shwartz:
