Upgrade to Nuget package Telerik.UI.for.AspNet.Core 2022.2.510 now requires nuget package Microsoft.AspNetCore.Mvc.NewtonsoftJson

[Martin]

In Core 6 project setting following global JSON option to maintain property case (such as required for returning JSON result for Kendo Grids), since the Telerik upgrade, you now have to manually add Microsoft.AspNetCore.Mvc.NewtonsoftJson nuget package

builder.Services.AddRazorPages().AddNewtonsoftJson(options => options.SerializerSettings.ContractResolver = new DefaultContractResolver());

or change to use System.Text.Json

builder.Services.AddRazorPages().AddJsonOptions(options => options.JsonSerializerOptions.PropertyNamingPolicy = null);

Hello Martin,

The latest Kendo version is much more lightweight than the previous versions that have more dependencies.

Instead of using the Newtonsoft library and manually adding Microsoft.AspNetCore.Mvc.NewtonsoftJson package, I would recommend setting the serialization options for the application by using the following approach:

//Program.cs

var builder = WebApplication.CreateBuilder(args);

// Add framework services.
builder.Services
	.AddRazorPages()
    // Maintain property names during serialization. See:
    // https://github.com/aspnet/Announcements/issues/194
    .AddJsonOptions(options =>
                options.JsonSerializerOptions.PropertyNamingPolicy = null);

// Add Kendo UI services to the services container
builder.Services.AddKendo();

The JSON Serialization in .NET Core 6 is described in the article below:
