b0bi@yandex.ru). Now we have purchased a license for Xamarin, I see it
in my profile www.telerik.com, but do not see on xamarin.com. How i can
link these two profiles? How do I start using this license?
Thank You.

Please note that direct link from your Telerik account to your Xamarin account is not needed in order to start working. Note that Xamarin is a platform for mobile development. On the other hand you have XamarinForms this is a UI toolkit allowing developers to easily create native user interface layouts that can be shared across Android, iOS, and Windows Phone. Please bear in mind that after installing and configuring Xamarin on your side you should be able to create applications using the guides of Xamarin. If you encounter any issues related with creating blank app utilizing XamarinForms you should contact their support or you can go through their documentation.
Once you configured everything and you are ready to create your first app you can install the Telerik UI for XamarinForms suite. This is an extended UI toolkit providing additional UI components to the stock XamarinFomrs toolkit. To do this you can go to your Telerik account and download the msi (if using Windows PC) and install the suite. If you encounter any issues while configuring any of the specified components from the toolkit you can contact us and we will try to assist you in the best possible way.
Next step would be to create your first blank application. You can do this by either using the stock XamarinForms template for creating Cross-Platform blank app or you can use our extended template that will get you started with our components right away. All the required references will be created and you will be able to get your hands on the code immediately. If you choose to manually create application based on the XamarinForms template you will need to reference all the required packages. You can find them in our Required Android Support Libraries article and in every Getting Started article of the components that you intend to use (e.g. RadCalendar).
In summary: Telerik and Xamarin are different companies providing different components. Xamarin provides the platform and standard UI toolkit while Telerik provides extended UI toolkit.
I hope this information brings clarification.

Then why can not I add external assembly and compilation Xamarin Forms ended with errors:
mandroid error XA9005: User code size, 2960767 bytes, is larger than 131072 and requires aВ IndieВ (or higher) License.
mandroid error XA9006: Using type `Android.Runtime.JNIEnv` requiresВ IndieВ (or higher) License.
As I already noted, Telerik license is required in order to download our binaries from our website. Once this is done the license is no longer required. In other words you application has nothing to do with Telerik license.
However, it should require license for Xamarin. This is why I suggest you contact their support in order to resolve the reported behavior.

@Alex
If you have an Indy licence you can't use Visual Studio, you have to use Xamarin studio and you can't build for iOS in windows. If you want to build for iOS and Android you'd have to use a Mac but you should be able to use Forms. If you want to use Visual Studio and Forms you can only build for Windows Phone if you have an Indy licence.

As Pavel says though, the licence issues you are experiencing are nothing to do with the Telerik controls.
