dnu restore: unknown keyword platform

[falconmick]

Hey guys.
Just spent the last 2 hours trying to get this damn thing to run... And yeah, no luck. I have tried heaps of things and got heaps of diferent errors, but I will start out with the initial error I get as the ones that were after might be due to my "fixes"

I have a fresh clone of my forked repo as suggested via Contributing.md I cd into: AspNet.Security.OAuth.Providers and type:

dnu restore

This is where the fun starts!

I get the following output:

Microsoft .NET Development Utility Clr-x86-1.0.0-rc2-20221

Apparently the issue is that it is tripping up on this part of the project.json:
"Microsoft.NETCore.App": { "type": "platform", "version": "1.0.0-*" }
As this is the only reference to platform (which is the issue) in the project.json
If I then go ahead and use delete the issue approach (bad I know, but hey, just run under 4.5?)

I get allot further :D yay!
(following removed from project.json)

    "netcoreapp1.0": {
      "dependencies": {
        "Microsoft.NETCore.App": { "type": "platform", "version": "1.0.0-*" }
      },

      "imports": [
        "dnxcore50",
        "portable-net451+win8"
      ]
    }

Yay! It builds

I then proceed to open the solution in the root folder and set the sample project as the startup project. I hit run (IIS) and I get the following:

Managed Debugging Assistant 'BindingFailure' has detected a problem in 'C:\Users\go_ha\.dnx\runtimes\dnx-clr-win-x86.1.0.0-rc2-20221\bin\dnx.exe'.

Additional information: The assembly with display name 'Microsoft.AspNet.Server.Kestrel' failed to load in the 'Load' binding context of the AppDomain with ID 1. The cause of the failure was: System.IO.FileNotFoundException: Could not load file or assembly 'Microsoft.AspNet.Server.Kestrel' or one of its dependencies. The system cannot find the file specified.

The same happens for the web command.

Does anyone have a solution for any of these? Really want to get to implementing Steam login.

Cheers :(

Hey,

The ASP.NET Core RC2/aspnet-contrib projects no longer work with DNX: you need to install .NET CLI to install and run the latest bits: https://github.com/dotnet/cli

I'll update CONTRIBUTING.md to reflect that.

Note that we already have a Steam middleware, that uses the generic OpenID2 provider: https://github.com/aspnet-contrib/AspNet.Security.OpenId.Providers/tree/dev/src/AspNet.Security.OpenId.Steam.

You can find the latest release on NuGet.org (for RC1) and the nightly builds on our MyGet repository (for RC2): https://www.nuget.org/packages/AspNet.Security.OpenId.Steam/

thanks for that.... Haha who would have known keeping up with beta/rc projects would be so hard (not).

A bit off topic, but how do you keep up to date with these changes?

@PinpointTownes I'm having RC1 version project in my Solution. I don't want to update that project to RC2 for the time being and adding new ASP.Net Core RC2 project in the same solution. I'm seeing the same error. How I can add two version ASP.net (RC1 and RC2) in the same solution ??????

@falconmick sometimes, I really wonder 😄

Unfortunately, you can't. At all. Either stay with RC1-only or migrate to RC2.
