Just make it compatible!
Kendo UI is server platform agnostic and should not have any issues with ASP.NET vNext and MVC6. Additionally, we already made our MVC server wrappers for Kendo UI compatible with the new version of ASP.NET. See this blog post for reference: http://www.telerik.com/blogs/telerik-ui-for-asp.net-mvc-supports-asp.net-vnext-rc Update: ASP.NET vNext RC1 compatible version is available via this public NuGet feed (https://www.nuget.org/packages/Kendo.Mvc/). Give it a spin and share feedback!
Any chance the ToDataSourceResult will support Async/Await? (see suggestions/3574176-add-todatasourceresultasync-method), this would be great for EF6 and the upcoming EF7
