Granted, I sometimes clearly miss the obvious and that might be what's going on here, so my apologies ahead of time.
I'm trying to get the Tagit tutorial going and I might be missing some supplemental document or project, but the tutorial doesn't it make it clear as to exactly what's needed to do the necessary steps. For instance, it notes "Once the project is created, adding a "Getting Started" component is as simple as adding a page, adding a reference to the appropriate Telerik namespace, dropping in a SlideView control, and connecting it to the view-model:". However, I'm not quite sure what type of View needs to be added (I was assuming a ContentView), to which project (I'm assuming the Portable project), and what viewmodel (I don't see any viewmodels)? When I tried adding a ContentView and inserted the SlideView sample code into the content area, I cannot compile as I get a number of errors including errors with "gs" files.
Once I get past this steps, will the future steps have the same perception of generality of directions?
What would be great is if I could download the completed project and that might give me some much needed hints as to what I'm missing, but if I want to do it entirely myself then it seems the tutorial is missing some other references.
For the record, I've always been extremely satisfied with the professionalism and help that the Telerik team has offered. I don't have any doubts that I'll be able to eventually get this going.
My system: I'm on Windows 10 (version 1803...and, no, I cannot upgrade to 1903 due to corporate standardization); Visual Studio 2019 (version 16.2.0), and I've updated Xamarin.Forms to 4.2.0.618605-pre2.
Hello,
I looked https://www.telerik.com/support/whats-new/xamarin-ui/release-history,
latest version ---> UI for Xamarin R2 2019 (version 2019.2.708.360)
But on visual studio nuget manager shows latest stable (version 2019.1.318.1)
How can i fix this?
Thanks
I wasn't able to find in the docs if Xamarin Forms 4.x was yet supported. Is there a place we can go to find out the latest Forms version Telerik supports?

Hi,
We're using Telerik controls in our Xamarin Forms application. We use the Material Visual package through out the application to ensure everything looks as expected on all platforms. This looks and works great. The only problem is that when using telerik controls like the auto complete view, it is jarring as the visual is just too different (i.e. the placeholder not moving to be smaller / top left).
As the material view is created / maintained by Xamarin - are you looking to ensure that your controls look / act the same where applicable?
Thanks,
Tom
Is there a way to detect killing the app by the user. If user kills an app from recent apps.
Thanks in advance.
Hi
I have followed the blog post on Using UI for Xamarin in Visual Studio for Mac and successfully added and logged on to the Telerik NuGet source. However I do not see any packages under this source.
Could someone please help
Thanks

Any components used in iOS will result in an app crash if AppShell is used. I have an example project if it's helpful, but it's simply the Visual Studio 2019 App Shell starter project with the AboutPage's button replaced with a RadButton. I'm using Forms v3.6.
The exception appears to happen when the trial popup is attempted to be shown. The page actually loads just fine. It works fine on Android.
Here is the exception:
{System.InvalidCastException: Specified cast is not valid.<

Is there any fix or workaround for this? It's making it impossible for us to evaluate Telerik beyond our logon screen. Thank you.
Hi all,
This happened randomly when we tap on a chart section to go to detail, sometimes it doesn’t fire selection event and sometime when it fires it gives null reference exception.and some times when we tap on a chart selection, application is terminating even its not giving any error in Xamarin forms IOS Project
