WebApi batch operation controller sample

[Samuel]

Do you have an example of ApiController implementation for batch operation?

I tried deleting 

a number of rows at a time but got this

{"Message":"The request entity's media type 'multipart/mixed' is not supported for this resource.","ExceptionMessage":"No MediaTypeFormatter is available to read an object of type 'PhoneBook' from content with media type 'multipart/mixed'.","ExceptionType":"System.Net.Http.UnsupportedMediaTypeException","StackTrace":"   at System.Net.Http.HttpContentExtensions.ReadAsAsync[T](HttpContent content, Type type, IEnumerable`1 formatters, IFormatterLogger formatterLogger, CancellationToken cancellationToken)\r   at System.Web.Http.ModelBinding.FormatterParameterBinding.ReadContentAsync(HttpRequestMessage request, Type type, IEnumerable`1 formatters, IFormatterLogger formatterLogger, CancellationToken cancellationToken)"}

Thanks

Hi Samuel, 

Thanks for contacting Syncfusion support. 

We suspect that the Web API is not configured with batch handler in the application. Please use the below link to troubleshoot your problem.

If you still face this problem, please share us the WebApi config to check the batch routing details.
