windows service and HttpSelfHostServer RRS feed

  • Question

  • I created a service and tried to run it with the next code :

     protected override void OnStart(string[] args)
                var httpSelfHostConfiguration = new HttpSelfHostConfiguration("http://localhost:1234");
                    defaults:new {id=RouteParameter.Optional});
               // httpSelfHostServer = new HttpSelfHostServer(httpSelfHostConfiguration, new ProcessRequest());
               // var task = httpSelfHostServer.OpenAsync();

    i try to run the service and before i reach this code i get error

    System.TypeLoadException: 'Inheritance security rules violated by type: 'System.Web.Http.SelfHost.HttpSelfHostConfiguration'. Derived types must either match the security accessibility of the base type or be less accessible.'

    what can cause this?
