Issue installing custom activity created by the VS Activity Creator

Help Studio
, , ,
1

I created a simple custom activity using the activity creator in visual studio and can’t seem to get it to install in UiPath. I am getting the following error:

Package ‘xxxx’ cannot be installed because it depends on package ‘System.Activities’. Studio provides its own version of the package ‘System.Activities’ and restricts its installation as a dependency.

I also uninstalled previously created custom activities and tried to reinstall them, and they are now all giving me this error even though I had already installed them before and haven’t changed them. I did upgrade to Studio 22.10.3, so I am assuming it is an issue with that. Does anyone know how I can resolve this problem?

It seems it was also posted here:

But there was no useful response.

Important to note: I am using .Net 6.0 for this.

Are you using version 4.0 of Activity Creator and UiPath project with ‘windows’ compatibility?

Yes. I checked both to be sure.

So versions are ok.
Could you please share your code from the .Acivities.Design.scproj file? (there are your package references)

I think it may be collision with package “System.Activities.Metadata”.
Can you remove this dependency?

I tried that, the same issue persists. It is weird that packages I have previously installed will no longer install since updating to 22.10.3. Earlier today I used the activities inside the packages in studio because I had installed them previously and I had no problems. When this new error showed up, I uninstalled the packages from studio and tried to reinstall them to see if they would also fail to install and they all failed with this error.
