This revit problem?

[Anonymous]

I made Revit add-in dll(called 'Test.dll')

In Test.dll project, i did add the Interop.ADOX.dll.

When i execute Test add-in in Revit 2013, an error occured(FileNotFoundException about Interop.ADOX.dll)

I tried to find this problem by debugging.

When i debugging,

Revit load only Test.dll, not load Interop.ADOX.dll

Is this revit problem?

It is a coincidence that someone had asked the very same question just a short while ago. You can find my reply there, but in a nutshell: ADOX.dll is not for you to use. You can only reference two Revit assemblies from your external add-in - RevitAPI.DLL and RevitAPIUI.dll. They combined expose all the functionality Revit API has to offer to 3rd party developers.
