I was doing a simple POC using Xamarin Forms, Xamarin UITest and VS App Center. I created a standard Forms and UI Tests projects, and setup a build in VSTS.
When trying to run the tests via App Center in VSTS (using the builtin task), I got an error
esoent no such file or directory
After much troubleshooting, and trying to run the appcenter CLI directly, I figured out the issue. You need v2.2 of the test-cloud.exe in order for this to work. The nuget package that is installed when creating a new UITest is 1.3X. As soon as upgraded the Nuget package to 2.2, everything was good.
