Unable to restore a ASP.NET Core 1.0 RTM solution

Question

I just converted a working RC2 web application to RTM and I have some issues publishing on IIS.

All the samples I have found are based on a NetCoreApp1.0 application. Due to some requirements, we are restricted to "net46".

Here is the project.json

{
  "version": "1.0.0-*",
  "dependencies": {
    "Domain": "1.0.0-*",
    "Microsoft.AspNetCore.Authentication": "1.0.0",
    "Microsoft.AspNetCore.Authentication.Cookies": "1.0.0",
    "Microsoft.AspNetCore.Authentication.Facebook": "1.0.0",
    "Microsoft.AspNetCore.DataProtection.SystemWeb": "1.0.0",
    "Microsoft.AspNetCore.Diagnostics": "1.0.0",
    "Microsoft.AspNetCore.Diagnostics.EntityFrameworkCore": "1.0.0",
    "Microsoft.AspNetCore.Http.Extensions": "1.0.0",
    "Microsoft.AspNetCore.Localization": "1.0.0",
    "Microsoft.AspNetCore.Mvc": "1.0.0",
    "Microsoft.AspNetCore.Server.IISIntegration": "1.0.0",
    "Microsoft.AspNetCore.Server.Kestrel": "1.0.0",
    "Microsoft.AspNetCore.StaticFiles": "1.0.0",
    "Microsoft.Extensions.Configuration.EnvironmentVariables": "1.0.0",
    "Microsoft.Extensions.Configuration.Json": "1.0.0",
    "Microsoft.Extensions.Logging.Console": "1.0.0",
    "Microsoft.Extensions.Logging.Debug": "1.0.0",
    "Microsoft.Extensions.Options.ConfigurationExtensions": "1.0.0",
    "PublicLib": "1.0.0-*",
    "PublicLib.Imaging": "1.0.0-*",
    "PublicLib.Interfaces": "1.0.0-*",
    "Storage": "1.0.0-*"
  },

  "tools": {
    "Microsoft.AspNetCore.Server.IISIntegration.Tools": {
      "version": "1.0.0-preview2-final"
    }
  },

  "frameworks": {
    "net46": {

    }
  },

  "buildOptions": {
    "emitEntryPoint": true,
    "preserveCompilationContext": true
  },

  "publishOptions": {
    "include": [
      "wwwroot",
      "web.config",
      "Views",
      "appsettings.json",
      "database.json",
      "PublicWeb.nuspec"
    ]
  },

  "packOptions": {

  },

  "scripts": {
    "postpublish": [ "dotnet publish-iis --publish-folder %publish:OutputPath% --framework %publish:FullTargetFramework%" ]
  }
}

This is the error I get

Errors in C:\Development\Path\To\Web\Application\project.json
    Package Microsoft.DotNet.ProjectModel 1.0.0-rc3-003121 is not compatible with netcoreapp1.0 (.NETCoreApp,Version=v1.0). Package Microsoft.DotNet.ProjectModel 1.0.0-rc3-003121 supports:
      - net451 (.NETFramework,Version=v4.5.1)
      - netstandard1.6 (.NETStandard,Version=v1.6)
    One or more packages are incompatible with .NETCoreApp,Version=v1.0.

If I change the "tools" sections as follows,

  "tools": {
    "Microsoft.AspNetCore.Server.IISIntegration.Tools": {
      "version": "1.0.0-preview2-final",
      "imports": "net451"
    }
  },

I manage to restore the solution, but when I try to publish the solution with dotnet publish .\Path\To\Web\Application\ -o .\tmp\public\, I get the following output

publish: Published to .\tmp\public\
Published 1/1 projects successfully

Event if it says Published 1/1 projects successfully, the .\tmp\public\web.config contains the following line.

<aspNetCore processPath="%LAUNCHER_PATH%" arguments="%LAUNCHER_ARGS%" stdoutLogEnabled="false" stdoutLogFile=".\logs\stdout" forwardWindowsAuthToken="false"/>

Whilst it used to contain

<aspNetCore processPath=".\PublicWeb.exe" arguments="" stdoutLogEnabled="false" stdoutLogFile=".\logs\stdout" forwardWindowsAuthToken="false" />

The second one is a working configuration for IIS on a deployed server.

Any suggestion on how to fix this?

Thanks

Answer 1

here is what helped me.

enter dotnet --version in the CMD, if it shows that you use version preview1 then here is what you will need to do in order to clean up the cache and enforce using preview2.

first make sure preview2 is in your computer, on windows it should be under C:\Program Files\dotnet\sdk if you have 1.0.0-preview2-003121 in the dir, then you are good to go, otherwise download the latest sdk first, and make sure you have the latest .Net core installed as well, and delete the dnx folder from your system since its not relevant anymore (changed to dotnet).

delete the preview1 sdk version from the dotnet sdk dir.

in your project folder edit your global.json file should be like this.

{
  "projects": [ "src", "test" ],
  "sdk": {
    "version": "1.0.0-preview2-003121"
  }
}

now restart your pc to make sure all services and processes is being restarted, run dotnet restore and now it works, it will first run some updates on the cache, but dont worry takes about a minute or 2 depends on your OS specs, then it will execute the restore.

I'm having an identical problem and was able to publish again by rolling back IISIntegration.Tools to 1.0.0-preview1-final

"Microsoft.AspNetCore.Server.IISIntegration.Tools": {
  "version": "1.0.0-preview1-final",
  "imports": "portable-net45+win8+dnxcore50"
}
