Using custom class



hello everyone,

I’m trying to use a Custom class in my robot.

I successfully managed to build a DLL with my class inside and then put this dll inside a .nupkg that i can find and install in the studio :

But I can’t find my Class or Namespace in import tab. I can’t use the class neither :


The dll was in release mode.

Any idea?

I followed your recommandations :

Can you attach your c# code


Here is the complete C# project (179.3 KB)


Can you confirm me the path where you are placing your nuget packege.?

If you are creating the custom activity, after installing the package search with class name of your custom activity.

Oh, you perhaps point something pertinent, i put it here : C:\Program Files (x86)\UiPath\Studio\Packages

Should I create %USERPROFILE%.nuget\Packages and put it there?


Nothing in Activities Panel with the class name :’(
