ASP.NET MVC 6 AspNet.Session Errors - Cannot resolve service for type?

Question

Ok, lately I have been having problems using the new Microsoft.AspNet.Session middleware for ASP.NET vNext (MVC 6). The error I get is

Unable to enable service for type 'Microsoft.Framework.OptionsModel.ConfigureOptions [Microsoft.AspNet.Session.SessionOptions] when trying to activate' Microsoft.AspNet.Session.SessionMiddleware '

occurs on all pages regardless of session use. The version of DNVM I am using is Beta5 x86, and all the packages in the project are also in beta. The project itself is an attempt to port the MVC 5 ASP.NET MVC 5 project without much luck. Below are links to resources that may be important:

• Project.json: http://tinyurl.com/project-json
• Startup.cs: http://tinyurl.com/startup-cs

There seems to be a problem with my configuration, but I'm not sure what to do with it ... Pls send help Dx

Unable to enable service for type "Microsoft.AspNetCore.Session.ISessionStore" when trying to activate "Microsoft.AspNetCore.Session.SessionMiddleware"

If you get this error message in ASP.NET Core, you need to configure session services in Startup.cs:

public void ConfigureServices(IServiceCollection services) { services.AddMvc() .AddSessionStateTempDataProvider(); services.AddSession(); } public void Configure(IApplicationBuilder app, IHostingEnvironment env) { app.UseSession(); app.UseMvcWithDefaultRoute(); }
