Aspnetcore: HttpPost Model Binding CamelCase

[Hantse]

Describe the bug

When try to post json payload as HTTP Post, controller don't bind with camelcase.

I have already this exception in post :

System.Text.Json.JsonReaderException: The provided data of length 95 has remaining bytes 2. 23/04/2019 11:39:11 at System.Text.Json.Serialization.JsonSerializer.ReadAsync[TValue](Stream utf8Json, Type returnType, JsonSerializerOptions options, CancellationToken cancellationToken) 23/04/2019 11:39:11 at System.Threading.Tasks.ValueTask1.get_Result()

To Reproduce

Steps to reproduce the behavior:

1. Create a new Project using last AspNetCore version
2. Create a simple classe with 1 property.
   public class TestClass { [JsonProperty("testProperty")] public string TestProperty { get; set; } }
3. Create a simple HTTPPost endpoint with FromBody input model
   [HttpPost] public void Post([FromBody] TestClass value) { }
4. Add Json & CamelCase configuration in startup
   services.AddControllers() .AddNewtonsoftJson(options => options.SerializerSettings.ContractResolver = new CamelCasePropertyNamesContractResolver());
5. Try HttpPost payload with lower case and upper case.
   ==> Work
   { "TestProperty": "testValue" }

==> Don't Work
{ "testProperty": "testValue" }

Expected behavior

I want a binding if model is send lower or upper case. (same as AspNetCore 2.2)

[pranavkm]

Do you have an application that reproduces the issue? Perhaps you application references an older version of Mvc.NewtonsoftJson.

[Hantse]

hum,

Swagger reference old package :

[Hantse]

Referencing Microsoft.AspNetCore.Mvc.NewtonsoftJson in project work fine.
