Error with Windows Compatibility Mode still not showing Custom Activities

[Ashish_Parjapati (Ashish)]

I have a custom activity which was running fine on UiPath 2021.10.5 , but after upgrading to 2022.10.3, the project type was windows-legacy then I converted that project to windows because my client is going to upgrade it to 2024.10.x and windows-legacy will not work on that one , after that it was not working ,so I tried to build a new .dll file by Visual studio 2015 , but initially it was showing in the manage packages but after some time it’s shows nothing,although path is correct . Then I searched on internet it says it can be a .net version error, and we have to migrate to .net6 then I followed the documentation and also this link

Windows Compatibility Mode still not showing Custom Activities

Hi there, I’ve try literally everything but when I try to create a new custom package, it is not showing in the Windows Compatibility Mode but it is showing in the legacy mode. I’ve been to some of the forum topic but nothing seems to work for me. Below are some of the steps I’ve performed: Add reference to the System.Activities.dll FYI: I’m using Visual Studio 2022 Community Edition. [image] Any help would be much appreciated. Note: I’ve been to some of the forums and nothing seems to w…

then I changed the target framework to 4.6.1 and build the package i tried with the solution (which I mentioned as 1 in picture) then I am getting an error
I created the .dll file and with the help of nuget package manager I added folder
net6.0-windows7.0

Also I followed the UiPath docs which also mentioned to add .net461 folder and adding files .dll and config
I tired by adding System.activites.DLL file in .net6 folder also

Error :-
Could not load type ‘System.Activities.XamlIntegration.ActivityXamlServices’ from assembly ‘System.Activities, Version=6.0.0.0, Culture=neutral, PublicKeyToken=null’.

Then I tried without the System.Activite.dll file , but nothing works
I also got another error like this

Windows Compatibility Mode still not showing Custom Activities

Hi @StefanSchnell, I have another issue here. Upon installing the package, I get the following: [image] Here is a link to my DLL and Nuget Package - https://easyupload.io/m/ce9kys

I followed this link saying solution for the error
Error :-
Could not load type ‘System.Activities.XamlIntegration.ActivityXamlServices’ from assembly ‘System.Activities, Version=6.0.0.0, Culture=neutral, PublicKeyToken=null’.

That I have to add a reference for the assembly

But it shows me error

If I remove the initial Reference of the System.Activities then another error comes again.
Not able to get the package working .
Thanks in Advance

Hi Ashish,

I have stopped using the Nuget Manager because I found a method to automatically create the package upon publishing the activities in Visual Studio.

I use Visual Studio 2022 and install some frameworks within VS 2022 plus some configurations in order to make it work. If you are interested, I could send you the rough guide and see if it works for you.

Hi Ashish,

Refer to the attached guide and see if it helps you. What version of UiPath Studio are you using? I’m still on 2023.4.7
