I am not able to install my custom package

Hi,

How did you create your custom activity?

If it’s created by library function of Studio, can you try the following step?

  1. Open your library project in Studio 22.10.3 or higher.
  2. We can use migration tool, then convert it to Windows compatibility.
  3. Publish it to nupkg.

If it’s created by Visual Studio, the following will help you.

Regards,
