[Masha]

Hi! im trying to migrate project from .net core2.2. to .net core3.0.

when i add line 

services.AddKendo();

i get an error:

System.AggregateException: 'Some services are not able to be constructed (Error while validating the service descriptor 'ServiceType: Kendo.Mvc.Rendering.IKendoHtmlGenerator Lifetime: Transient ImplementationType: Kendo.Mvc.Rendering.KendoHtmlGenerator': Could not load type 'Microsoft.AspNetCore.Mvc.Internal.ClientValidatorCache' from assembly 'Microsoft.AspNetCore.Mvc.Core, Version=3.0.3.0, Culture=neutral, PublicKeyToken=adb9793829ddae60'.)'

without this line, everything works fine

Hello Masha,

Note, that official support for .NET Core 3.0 is provided starting with Telerik UI for ASP.NET Core version 2019.3.1023. As you have noticed, the error should be fixed when the latest UI for ASP.Net Core version is installed.

Hi JM,

I noticed that my colleague Veselin has already answered the question in the Forum thread on the same topic linked below

I would suggest you keep the conversation in a single thread.
