A recurring question just came up again, on handling conflicts between DLLs loaded by Revit add-ins.
For instance, this can be caused by a scenario in which add-ins A and B both make use of library DLL C, but specify different versions. A soon as the first add-in has loaded its version of C, the second add-in is prevented from loading the version it requires and cannot run.
I have no official solution to suggest for this, but here are several discussion threads and articles suggesting various workarounds:
- Proper way to handle App.config bindingRedirects in Revit add-in
- Loading different versions of same third party library
- Loading multiple versions of the same DLL used in Revit plug-ins
- The Managed Extensibility Framework MEF offers an option but requires a lot of changes.
- A Plug-In System Using Reflection, AppDomain and ISponsor
- You can also use ILMerge to merge all of your DLLs into one single .NET assembly, cf. the CodeProject article on Merging .NET assemblies using ILMerge
