Microsoft.AspNet.WebApi.Client - ReadAsAsync - IgnoreSerializableAttribute = true

[bwilliams1]

Microsoft.AspNet.WebApi.Client exposes an extension method HttpContentExtensions.ReadAsAsync which depends on MediaTypeFormatterCollection which creates a default set of MediaTypeFormatter one of which is JsonMediaTypeFormatter which depends on Newtonsoft.Json. This media type formatter has a setting IgnoreSerializableAttribute = true buried within SerializerSettings.ContractResolver that we want to set. It appears the only way to do this is by using an override of ReadAsAsync that takes an enumerable of custom media type formatters.

Is there a global way to set IgnoreSerializableAttribute = true for all media type formatters at a global level? This is behavior we never want.

With the current approach we have to visit ~75 instances of ReadAsAsync and switch them to a custom extension method that uses a JsonMediaTypeFormatter with IgnoreSerializableAttribute = true which is pretty tedious and testing intensive. Furthermore, we have to enforce the usage of the custom extension and "ban" the native ReadAsAsync with Roslyn Analyzers.

public static Task<T> ReadAsAsyncAndIgnoreSerializableAttrib<T>(this HttpContent content)
  var mediaTypeFormatter = new List<MediaTypeFormatter>() { new System.Net.Http.Formatting.JsonMediaTypeFormatter()
  
  {
	  SerializerSettings = new JsonSerializerSettings()
	  {
		  ContractResolver = new DefaultContractResolver()
		  {
			  IgnoreSerializableAttribute = true
		  }
	  }
  } };
  
  return content.ReadAsAsync<T>(mediaTypeFormatter);
}

Hi. It looks like this is a question about how to use ASP.NET Core. While we do our best to look through all the issues filed here, we are not a general-purpose forum. To get a faster response we suggest posting your questions to StackOverflow using the asp.net tag.

we are actually using this in .net framework ASP.NET application. I did repost this on stack overflow as advised.
