The request body is a non-rewindable stream; it can be read only once. The formatter has already read the stream and populated the model. We’re not able to read the stream again in the action filter. You could try: public class LogAttribute : ActionFilterAttribute { public override void OnActionExecuting(HttpActionContext actionContext) { var myModel = actionContext.ActionArguments[“myModel”]; … Read more
The static stuff is going away. If your not using a Service Locator of some type you’re going to have implement your own “ObjectFactory” as referenced here: public static class ObjectFactory { private static readonly Lazy<Container> _containerBuilder = new Lazy<Container>(defaultContainer, LazyThreadSafetyMode.ExecutionAndPublication); public static IContainer Container { get { return _containerBuilder.Value; } } private static Container … Read more
If you are using OData V4, replace using System.Web.Http.OData; With using Microsoft.AspNet.OData; (Please check the comments for the latest library) in the ODataController works for me.
If you need this to only affect a particular field, create a converter type first: public class OnlyDateConverter : IsoDateTimeConverter { public OnlyDateConverter() { DateTimeFormat = “yyyy-MM-dd”; } } and then add this attribute to whatever fields/properties you want this for: [JsonConverter(typeof(OnlyDateConverter))]
As Joe pointed out, culture is transferred by the HttpContext in ASP.NET. The way ASP.NET does this is by installing a SynchronizationContext when a request starts, and that context is also used to resume asynchronous methods (by default). So, there are a couple of ways to approach the problem: you can either write your own … Read more
Here is an simple error DTO class public class ErrorDto { public int Code {get;set;} public string Message { get; set; } // other fields public override string ToString() { return JsonConvert.SerializeObject(this); } } And then using the ExceptionHandler middleware: app.UseExceptionHandler(errorApp => { errorApp.Run(async context => { context.Response.StatusCode = 500; // or another Status accordingly … Read more
Two things: You don’t need quotes “” around the content type and accept header values in Fiddler: User-Agent: Fiddler Content-Type: application/xml Accept: application/xml Web API uses the DataContractSerializer by default for xml serialization. So you need to include your type’s namespace in your xml: <TestModel xmlns=”http://schemas.datacontract.org/2004/07/YourMvcApp.YourNameSpace”> <Output>Sito</Output> </TestModel> Or you can configure Web API to … Read more

I ran into something similar in .NET 4.0 (no async/await). Using the debugger’s Thread stack I could tell that ReadAsMultipartAsync was launching the task onto the same thread, so it would deadlock. I did something like this: IEnumerable<HttpContent> parts = null; Task.Factory .StartNew(() => parts = Request.Content.ReadAsMultipartAsync().Result.Contents, CancellationToken.None, TaskCreationOptions.LongRunning, // guarantees separate thread TaskScheduler.Default) .Wait(); … Read more
Note/Update: The below code was for .NET Core 1.1 Since .NET Core 1 was so very RTM, authentication changed with the jump from .NET Core 1 to 2.0 (aka was [partially?] fixed with breaking changes). That’s why the bellow code does NOT work with .NET Core 2.0 anymore. But it will still be a useful … Read more
