Question

In a ASP.Net application I have a class.

This class need reference to two assemblies that I wrote before:

FMDriver.dll
MyWorldObj.dll

Each one of those assemblies use MySql.Data.dll but with different versions.

If I add references from my new project (with Copy Local = true) to those two assemblies I get errors because MYWorld.dll can’t find MySql.Data.dll. Maybe that’s because it uses an older version af the MySql library? If I remove reference to FMDrvier.dll MyWorldObj work properly.

Answer 1

I have used Binding Redirects before to get all referenced assemblies to use one version. Not sure if this solution will work for you.

You essentially provide an old version and a new version:

<bindingRedirect  
   oldVersion="old assembly version"
   newVersion="new assembly version"/>

Then make sure the new version .dll is in the bin if your project.

Otherwise it looks like time to upgrade the assembly to use the same version.
