    We are trying to build an app store package in windows 10 (Right click on project -> Store -> Create App Packages), but we are getting the following build error:

    MCG0021: MCG0021:InvalidMethodImpl Method 'Telerik.UI.Drawing.D2DBrush Telerik.UI.Drawing.D2DSolidColorBrush.Clone()' does not have a valid MethodImpl. Every Windows Runtime method should have a MethodImpl indicating the corresponding Windows Runtime interface. Referenced Windows Runtime library 'Assembly(Name=Telerik.UI.Drawing, Version=, Culture=neutral, PublicKeyToken=null, Location=<project-path>\in\Telerik.UI.Drawing.winmd, ContentType=WindowsRuntime)' appears malformed.

    We are using the latest nugget package, but haven't pulled down the source yet to make these changes. Are there any plans to release an update that fixes this?

    Hi Lev,

    I can see this has already been discussed in a support ticket. I will paste our reply here, so that it is available for the public.

    Thank you for contacting us! Currently, our suite is not fully compatible with the new programming model (UWP). Our plan is to release a version that targets Windows 10 in September.

     We have issued early adopters program where you can subscribe and receive bits that target UWP and this issue is addressed.

    You can receive the bits by sending email to

    Best regards,
