CreatedAtRoute: No route matches with empty route values

I'm currently struggling with CreatedAtRoute, below are the details.
Desired solution in the future
Return object and URI in location header linking to endpoint GetGlobalSettings.
Current situation and problem
I have the following POST endpoint for resource creation which returns CreatedAtRoute like this return CreatedAtRoute(nameof(GetGlobalSettings), result.Data);
The route set in the location header should link to the endpoint with this method head:
[HttpGet]
[ProducesResponseType(StatusCodes.Status200OK)]
[ProducesResponseType(StatusCodes.Status404NotFound)]
public async Task<ActionResult<GlobalSettingDto>> GetGlobalSettings()
With this I always get the following exception:
System.InvalidOperationException: No route matches the supplied values.

I have API-versioning active, so I also tried the CreatedAtRoute-call like this:
var routeValues = new { version = "1.0" };
return CreatedAtRoute(nameof(GetGlobalSettings), routeValues, result.Data);
But this still throws the same error.

In your case, you should use CreatedAtAction:
return CreatedAtAction(nameof(GetGlobalSettings), routeValues, result.Data);
Regarding the difference between CreatedAtAction and CreatedAtRoute, you can see this thread.

How can i make a multipart/form-data request with string

I'm trying to make a request on this site: https://textitor.com/ to create pastes but I saw that the content-type was multipart/form-data.
I saw on Stackoverflow several explanations to make a multipart/form-data request with a file but I couldn't find how to do it with strings.
So I'm hoping that someone will be able to help me

Enable CORS in Azure Mobile Services - OPTIONS not authorized

I am creating .Net web services using Azure Mobile Services. The services themselves work fine, but I want to enable CORS.
My Global.asax contains:
protected void Application_BeginRequest(object sender, EventArgs e)
{
HttpContext.Current.Response.AddHeader("Access-Control-Allow-Origin", "*");
if (HttpContext.Current.Request.HttpMethod != "OPTIONS") return;
HttpContext.Current.Response.AddHeader("Access-Control-Allow-Methods", "GET,POST");
HttpContext.Current.Response.AddHeader("Access-Control-Allow-Headers",
"Authorization, Origin, Content-Type, Accept, X-Requested-With,x-zumo-application,x-zumo-installation-id");
HttpContext.Current.Response.AddHeader("Access-Control-Max-Age", "1728000");
HttpContext.Current.Response.End();
}
My WebAPIConfig.cs contains:
public static void Register()
{
ConfigOptions options = new ConfigOptions();
HttpConfiguration config = ServiceConfig.Initialize(new ConfigBuilder(options));
var cors = new EnableCorsAttribute("*", "*", "*","*");
config.EnableCors(cors);
config.Routes.MapHttpRoute("DefaultApiWithAction", "Api/{controller}/{action}");
}
My request/response:
OPTIONS http://********.azure-mobile.net/API/MyLogin?username=username&password=password&email=testtest%40example.com&_=140191793307 HTTP/1.1

<Error><Message>Authorization has been denied for this request.</Message></Error>

There is a workaround for enabling CORS in Mobile Services here:
https://gist.github.com/HenrikFrystykNielsen/6c934be6c6c8fa9e4bc8
You don't need the Application_BeginRequest part -- requests/responses don't go through that code path -- they go through the OWIN pipeline. Good thing is that you only need the gist above to get going.
Hope this helps!

Cannot Return Custom HTTP Error Details Remotely

This is a strange one. I'm running MVC 3 and have a custom action result that wraps exceptions and returns a message along with the standard HTTP error.
public class ExceptionResult : ActionResult
{
private readonly Exception _exception;
public ExceptionResult(Exception exception)
{
_exception = exception;
}
public override void ExecuteResult(ControllerContext context)
{
var response = context.HttpContext.Response;
response.ClearHeaders();
response.Cache.SetNoStore();
response.ContentType = ContentType.Json;
var baseEx = _exception as BaseException ?? new ServerException(_exception);
var result = baseEx.GetResult();
var json = result.ToJSON();
response.Write(json);
response.StatusCode = (int)result.Status.Code;
}
}
When I run this locally I get exactly what I expect:
HTTP/1.1 400 Bad Request
Cache-Control: no-store
Content-Type: application/json; charset=utf-8
Server: Microsoft-IIS/7.5
X-AspNet-Version: 4.0.30319
Date: Thu, 01 Dec 2011 19:00:03 GMT
Content-Length: 81
{"error":"invalid_request","error_description":"Parameter grant_type is missing"}
But when I try to connect from a different machine I get the standard IIS error message instead:
HTTP/1.1 400 Bad Request
Cache-Control: no-store
Content-Type: text/html
Server: Microsoft-IIS/7.5
X-AspNet-Version: 4.0.30319
Date: Thu, 01 Dec 2011 19:02:33 GMT
Content-Length: 11
Bad Request
UPDATE
There must be some http module somewhere in the IIS pipeline that is swallowing the response and rewriting the content. I wrote a module to log the request and response and it's returning exactly what I expect however what actually makes it to the browser is wrong.

SOLUTION
Thanks to a little sleuthing I was able to figure it out. I setup IIS tracing which confirmed my suspicions that it was related to the customerrormodule which was intercepting my requests and overwriting my error messages. I kept monkeying with the
<system.web>
<customErrors />
<system.web>
settings but to no avail. I was on the right track, but since it's IIS 7 that I'm running I needed to change the correct web.config section like this:
<system.webServer>
<httpErrors errorMode="Detailed" />
</system.webServer>
Now all my custom JSON messages come through perfectly. Big thanks to Jason Finneyfrock for the tag team on this one.

In your web.config, do you have httpErrors defined to only be DetailedLocalOnly? I'm not sure whether or not the content would be removed in this situation.
http://www.iis.net/ConfigReference/system.webServer/httpErrors

I came across this, not sure if it will help:
context.HttpContext.Response.TrySkipIisCustomErrors = true;
