Ambiguous calls when using AddAuthentication in ASP.NET Core RC2

Question

I have installed asp.net core rc 2. I'm trying to create jwt token auth. In rc 1 all workrs very well. Even if you create a standard project, he did not start, because there are errors=( Correcting mistakes, i'm adding in startup.cs an code :

  public void ConfigureServices(IServiceCollection services)
    {
        // Add framework services.
        services.AddApplicationInsightsTelemetry(Configuration);
        var connection = "Data Source=DESKTOP-R3AP4AT\\SQLEXPRESS;Initial Catalog=Guide;Integrated Security=True;Connect Timeout=15;Encrypt=False;TrustServerCertificate=True;ApplicationIntent=ReadWrite;MultiSubnetFailover=False";
        services.AddDbContext<GuideContext>(options => options.UseSqlServer(connection));
        services.AddAuthentication();
        services.AddMvc();
    }

Adding in project.json libs:

"AspNet.Security.OpenIdConnect.Server": "1.0.0-beta4",

and there was an error : All project.json:

Answer 1

Don't mix different RC versions together. Your project.json mixes RC1 and RC2 modules.

All of them have to be RC2 or it won't work. There are dozen of breaking changes from old versions to new ones.

"Microsoft.AspNet.Authentication": "1.0.0-rc1-final",
"Microsoft.AspNet.Security.OpenIdConnect" :  "1.0.0-beta3",
"AspNet.Security.OpenIdConnect.Server": "1.0.0-beta4"

These lines are wrong, they are outdated packages.

"Microsoft.AspNetCore.Authentication": "1.0.0-rc2-final",
"Microsoft.AspNetCore.Authentication.OpenIdConnect" :  "1.0.0-rc2-final",
"AspNet.Security.OpenIdConnect.Server": "1.0.0-beta5-final"

Should work.
