Custom Activity with Dependencies - Unable to resolve dependency

Good day,

I am trying to create a custom activity using VS2017 Class Library (.NET Framework).

I can create the Activity nicely with Nuget Package Explorer and it works.
I now added “Microsoft.ProjectOxford.SpeechRecognition-x64” in my visual studio Class library as a nuget
package to use.

Now when I try to install the activity in UiPath, the dependency cannot be resolved.

Is there any links or documentation that shows you have to include the dependency correctly?


You should try to add as another package source (

The issue was that my activity and dll package was set to 32 bit.
using - Microsoft.ProjectOxford.SpeechRecognition-x32” fixed the issue.
