HI,

It may be better to use UiPath.Workflow.Runtime 6.0.0-20220909-01 instead of 6.0.3 in your project. Can you try this?

Regards,

Hi

Could you please provide your code with package references from .Actrivities.Design csproj file?
Something like this:

And make sure your target framework is net6.0-windows (You are using activity creator v4)

<TargetFrameworks>net6.0-windows</TargetFrameworks>

I have degraded the dependacy and created new package, it’s installed successfully. But the activity is not showing in studio Activities panel.

Ok, check if there is a new nuget file after publishing

I really wish UiPath would fix all the problems in v4 (v5?) instead of everyone having to share work arounds. It doesn’t work near as good as the v3 (Windows-Legacy) version and they keep pushing that Windows-Legacy will be depreciated.

  • The template can’t create a project if you don’t EXPLICITLY have .Net Framework 4.6.1 installed, even though it’s not used.
  • The v4 looks for the older supporting libraries (beta) instead of the current versions.
  • The template doesn’t default to build NuGet files in a “._nuget” folder
  • Heck, it fails to compile all projects after adding the first activity.

Come on UiPath. Step up the game please.

Failing to Builld turned out to be the subfolder depth plus lengthy filename. Exceeded 255 characters on some file paths.

Maybe V5 will improve some of these autogenerated “features”.
