asp.net-web-api2

I have a .net web api hosted on IIS 7 on a remote server which uses windows authentication. I want to access the web api using Angular 2 using TypeScript with node . Earlier i was getting an error 'Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource' I added this on the hosted Application's web.config <httpProtocol> <customHeaders> <add name="Access-Control-Allow-Origin" value="*" /> </customHeaders> But now i get Unauthorised 401 error. I have read about adding the following code to allow cross domain

I am using PushStreamContent to keep a persistent connection to each client. Pushing short heartbeat messages to each client stream every 20 seconds works great with 100 clients, but at about 200 clients, the client first starts receiving it a few seconds delayed, then it doesn't show up at all. My controller code is // Based loosely on https://aspnetwebstack.codeplex.com/discussions/359056 // and http://blogs.msdn.com/b/henrikn/archive/2012/04/23/using-cookies-with-asp-net-web-api.aspx public class LiveController : ApiController { public HttpResponseMessage Get(HttpRequestMessage request) {

The Scenario I've recently built an ASP.NET WEB API , and have protected its resources using OAuth Bearer Access Tokens. I've used the Client_Credentials Flow, as it will be accessed by clients as opposed to users. Here's the thing, when a client has successfully provided the client_id and the client_secret they receive a response like the following :- { "access_token": "<Access Token>", "token_type": "bearer", "expires_in": 1199, "refresh_token": "<Refresh Token>" } Refresh Tokens. Not knowing much about refresh tokens, i immediately assumed that a client would be able to provide the OAuth

I have tested the the call to the $metadata using postman and have found that when the MaxDataServiceVersion header is supplied the service always returns a 404 error. I have other posts about this using Breeze, but the best answer I can find simply says to comment out the line that adds this header. We are using SAPUI5 ODataModel in our client application and commenting out that header is not an option. Web API Config: ODataConventionModelBuilder builder = new ODataConventionModelBuilder(); builder.EntitySet<TBLMATERIAL>("TBLMATERIALs").EntityType.HasKey(o => o.MaterialNumber); config

I am encountering an issue while sending some JSON from an AngularJS application to a ASP.Net WebAPI 2 back-end. What happens is that some properties from the incoming request are set to null during deserialization. Part of the request where the deserialization bug occurs: 12: {row: 9, column: 1, order: 13,…} column: 1 domainEntityProperty: {$id: "157", id: 2616,…} order: 13 renderType: {$id: "39", id: 1, class: "input"} row: 9 Above snippet is piece of the request that is being sent. It's a so called screen property being saved. The request has an array of these objects. The strange thing is

I have a basic Identityserver4 implementation based on the quick start sample . In my startup I have the following: public void ConfigureServices(IServiceCollection services) { // configure identity server with in-memory stores, keys, clients and scopes services.AddIdentityServer() .AddTemporarySigningCredential() .AddInMemoryApiResources(Config.GetApiResources()) .AddInMemoryClients(Config.GetClients()); } public void Configure(IApplicationBuilder app) { ... app.UseIdentityServer(); } I want to extend the IdentityServer4 workflow so that after the access token is generated I can run business

I have a Web.API endpoint that takes an object like this as a parameter: public class Person { public string FirstName { get; set; } public string LastName { get; set; } public int Age { get; set; } public UserName UserName { get; set; } } For example: [Route("api/person")] [AcceptVerbs("POST")] public void UpdatePerson(Person person) { // etc. } I've defined a custom JsonConverter to convert from a JSON string property to my custom UserName class: public class UserNameJsonDeserializer : JsonConverter { public override bool CanConvert(Type objectType) { return objectType == typeof(UserName); }
