ASP.NET (C#) Question

config.MapODataServiceRoute error

I am currently following this guide -> Link to asp.net website

As the guide says I added all the necessary packages via the nuget console and added the necessary usings to the WebApIConfig file. . But when I added the endpoint register method VS gave me an error.

The method I added:

public static void Register(HttpConfiguration config)
{
// New code:
ODataModelBuilder builder = new ODataConventionModelBuilder();
builder.EntitySet<Product>("Products");
config.MapODataServiceRoute(
routeName: "ODataRoute",
routePrefix: null,
model: builder.GetEdmModel());
}


The Error VS gave me:

Error 1 'System.Web.Http.HttpConfiguration' does not contain a definition for 'MapODataServiceRoute' and no extension method 'MapODataServiceRoute' accepting a first argument of type 'System.Web.Http.HttpConfiguration' could be found (are you missing a using directive or an assembly reference?) C:\Users\rvcamp\Desktop\odataTest\odataTest\App_Start\WebApiConfig.cs 29 20 odataTest


I checked the comments of the guide but this error is not mentioned, also I can not resolve the error either. What am I doing wrong?

Answer

I just had this problem. Very frustrating.

I resolved it by adding this in the references at the top of the code page

using System.Web.OData.Extensions;

Right clicking the method did not bring up the resolve menu item either.

Reinstalling everything did no resolve anything for me.
