I have migrated my Xamarin.iOS project to .Net6 Xamarin.iOS  
I’m trying to integrate Dynatrace in to my Xamarin.iOS .Net6 application.

According to the document for Xamarin, I installed&nbsp;[Dynatrace.OneAgent.Xamarin](https://www.nuget.org/packages/Dynatrace.OneAgent.Xamarin)&nbsp;package, add the config file into my project, and input the code into AppDelegate.cs file in “FinishedLaunching()”

Then I rebuild my project, and I got following error:  
**The name ‘Agent’ does not exist in the current context**

Which nuget version of Dynatrace is supporting .Net6 Xamarin.iOS applications ?

So you are using Xamarin with NET6.0? Just to clarify for us, so we can have a detailed look/understanding. Could you please try to use version 1.279.1 of MAUI package. It contains NET6.0 and we believe this might solve your case. I am specifying 279 now as 283 is missing NET6 because of supportability reasons (If your use case turns out to be true, we will readd this for 285).
