services.AddKendo();

[Mehmet]

Hi Telerik,

When I use the "services.AddKendo();" command,the program gives the following message.

I have followed the instructions on your page, the situation has not changed.

I first tried it with version 2016.3.118, then I tried it with the latest promotional version, the message has not changed.

Best regards,

Hi Mehmet,

Below you will find a link to our Forum where such an issue has been discussed.

- https://www.telerik.com/forums/services-addkendo()-issue#mXOTnJoYUUGjcw2y_JBcvw

As you could see in the Forum thread, such error should not appear if the latest Telerik UI for ASP.NET Core version is installed. To resolve the issue, I would suggest you to double-check if the latest version of Telerik UI for ASP.NET Core is installed. Then, you could follow the steps described in the Creating Application article linked below

- https://docs.telerik.com/aspnet-core/getting-started/first-steps#creating-the-application

Another possibility is to create a new project by using the Create New Project Wizard. if you have installed Telerik UI for ASP.NET Core from the .msi executable available in your Telerik Profile, you should have access to the Telerik Extensions and you will be able to use the Create New Project Wizard. Thus, all the needed steps will be set up automatically.

I hope the provided information will help you to resolve the issue.

I have the latest version of the dll and I still get the error that says:

TypeLoadException: Could not load type 'Microsoft.AspNetCore.Mvc.Internal.ClientValidatorCache' from assembly 'Microsoft.AspNetCore.Mvc.Core, Version=8.0.0.0, Culture=neutral, PublicKeyToken=adb9793829ddae60'.

Hi Samrat,

Would it be possible for you to share the relevant "Program.cs" or "Startup.cs" files in which the "services.AddKendo()" is invoked? This will help me get a better overall understanding of the current infrastructural setup you have employed for your ASP.NET Core application.

Hi Neli,

 

We skipped that detail in Telerik 2016 version, I tried in 2020 version, it works, thanks for the answer
