Xaml file not working

[PrankurJoshi]

Have you tried to update UiPath.UiAutomation.Activities first?

Try this as well

Unable to resolve dependency 'Microsoft.Rest.ClientRuntime'

I had this problem today in a new installation of UiPath. While trying to install UiPath.Framework.Activities a message about Microsoft.Rest.ClientRuntime dependency appeared. I have solved my problem by downloading the nuget package, and installing manually into UiPath, through the Package Manager. https://www.nuget.org/api/v2/package/Microsoft.Rest.ClientRuntime/2.3.14

This should help you

Thanks,
