Hi,

I am trying to add the Xamarin libraries to a project I am working on. I have the Nuget source configured properly: When I search for Telerik libraries they all appear correctly, however they fail to install.

Restoring packages for /******.csproj...
Restoring packages for .NETStandard,Version=v2.1...
  GET https://api.nuget.org/v3-flatcontainer/telerik.ui.for.xamarin.datacontrols.lite/index.json
  NotFound https://api.nuget.org/v3-flatcontainer/telerik.ui.for.xamarin.datacontrols.lite/index.json 306ms
Resolving conflicts for .NETStandard,Version=v2.1...
Unable to find package Telerik.UI.for.Xamarin.DataControls.Lite. No packages exist with this id in source(s): nuget.org
Package restore failed. Rolling back package changes for '****'.

I periodically can not connect to NuGet from Visual Studio. This is happening at the moment. Is the nuget.telerik.com server down?

When I use this in my browser...  

https://nuget.telerik.com/nuget

I am prompted for login, and after entering my credentials I see the page below

but in Visual Studio, it keeps on asking for my credentials when I try to use NuGet.

We had a Xamarin 3 iOS application built using Telerik 2018 components and it was working fine until the recent update in iOS. However, after the iOS update to 15, Xamarin 3 iOS app started crashing. Then we updated our app to Xamarin 5 and were able to successfully compile and run it on an iOS 15 simulator. But the Telerik 2018 controls did not render on screen. So we upgraded Telerik control to 2021 version (trial), and now we are having following error which broke the compilation of the entire project.

you must add a reference to assembly 'netstandard version=2.0.0.0 xamarin

It seems that Telerik 2021 controls have a dependency on netstandard library which is either not supported or cannot be installed from NuGet. 

It would be great if you could help us to resolve this issue. This way we would recover our app from crashes, and purchase the latest updates for Telerik.

Hi, I'm getting the following error when building my Xamarin.Forms project on iOS. Weirdly enough it was working fine the other day and now it consistently gives me this error. The application itself launches on iOS but half the pages are missing and some pages are missing components. 

The type initializer for 'Telerik.XamarinForms.SkiaSharp.SkiaPainter' threw an exception.  
  Exception of type 'System.Exception' was thrown.

I am using RadFlowDocument to create a PDF that will be shared by the user. This is a Xamarin Forms app.

I am finding little documentation specific to using RadFlowDocument in the Xamarin context.

The RadFlowDocumentEditor.InsertImageInline method takes a Stream but I don't know how to get a Stream from a Xamarin Forms resource.

Hi.

I'd like a little advice and suggest a new control.

Prior to iOS14 we used https://github.com/jamesmontemagno/MediaPlugin as our media picker in our Xamarin forms app.

Since https://github.com/jamesmontemagno/MediaPlugin does not work on iOS14 and is not being actively developed, we switched to xamarin/Essentials and now face a rotation issue (https://github.com/xamarin/Essentials/issues/1514) for a long time.

There seems not to be any alternatives!

What are you doing?

And how about developing a reliable upload control?

Best regards

Morten

I have downloaded the sample code, and followed the instructions laid out here:

https://github.com/telerik/telerik-xamarin-forms-samples/tree/master/ERP

I have successfully published the service app, and am able to browse to the url just fine.  Additionally, I can see the SQL objects and data got created in the sample database.  I updated the web.config with the Azure SQL Connection info

I have updated the constants.cs file in the ErpApp solution with the URL from the Azure app service as well.

However, when I launch the app from debug in VS 2019, all the tabs in the mobile app spin for a few seconds, and then bring up empty screens, almost like there's no data to connect to, or some kind of permissions is not allowing it to pull down the data from Azure SQL.  Interestingly enough, I am able to add a customer, but I have no idea where it's adding it to if it can't connect to the database!

Any thoughts here?   Feels like I'm really close, but something isn't quite hooked up correctly I don't think.
