The type or namespace name 'Activities' does not exist in the namespace 'Microsoft' (are you missing an assembly reference?)

Hi,

I have an “Invoke Code” activity in my automation, I write C# codes in it to get a DataTable from MS sql server, it works perfectly fine in UiPath Stutio on my own laptop, but when I publish the package to Orchestrator and deploy it on another machine, the robot does not work, the log says “No compiled code to run\nerror CS0234: The type or namespace name ‘Activities’ does not exist in the namespace ‘Microsoft’ (are you missing an assembly reference?)”.

Could anyone please help? Thanks!

I solved the problem myself, just go to studio → Manage Package, add the package “Microsoft.Activities.Extensions”, then re-deploy the solution package to testing machine.

Thank you for that solution and taking time to share it here. We have been debuging for while to solve that error code CS0234 on a single Invoke Code activity in the whole project.
We finally have a solution to this problem!
