sdk: dotnet restore: One or more packages are incompatible with .NETCoreApp,Version=v1.0.

After adding “Microsoft.AspNetCore.Authentication.Facebook” dotnet refuses to restore. Even after removing the package, project.json will still not restore.

Steps to reproduce

My project.json looks like this:

{
  "dependencies": {
    "Microsoft.NETCore.App": {
      "version": "1.0.0-rc2-3002702",
      "type": "platform"
    },
    "Microsoft.ApplicationInsights.AspNetCore": "1.0.0-rc2-final",
    "Microsoft.AspNetCore.Mvc": "1.0.0-rc2-final",
    "Microsoft.AspNetCore.Server.IISIntegration": "1.0.0-rc2-final",
    "Microsoft.AspNetCore.Server.Kestrel": "1.0.0-rc2-final",
    "Microsoft.Extensions.Configuration.EnvironmentVariables": "1.0.0-rc2-final",
    "Microsoft.Extensions.Configuration.FileExtensions": "1.0.0-rc2-final",
    "Microsoft.Extensions.Configuration.Json": "1.0.0-rc2-final",
    "Microsoft.Extensions.Logging": "1.0.0-rc2-final",
    "Microsoft.Extensions.Logging.Console": "1.0.0-rc2-final",

    "Microsoft.AspNetCore.Mvc.TagHelpers": "1.0.0-rc2-final",
    "Microsoft.AspNetCore.StaticFiles": "1.0.0-rc2-final",
    "Microsoft.AspNetCore.Razor.Tools": {
      "version": "1.0.0-preview1-final",
      "type": "build"
    },
    "Microsoft.AspNetCore.Authentication.Facebook": "1.0.0-rc2-final"
  },

  "tools": {
    "Microsoft.AspNetCore.Server.IISIntegration.Tools": {
      "version": "1.0.0-rc2-20507",
      "imports": [ "portable-net40+sl5+win8+wp8+wpa81" ]
    },
    "Microsoft.AspNetCore.Razor.Tools": {
      "version": "1.0.0-preview1-final",
      "imports": "portable-net45+win8+dnxcore50"
    },
    "Microsoft.EntityFrameworkCore.Tools": {
      "version": "1.0.0-preview1-final",
      "type": "build"
    },
    "Microsoft.VisualStudio.Web.CodeGeneration.Tools": {
      "version": "1.0.0-preview1-final",
      "type": "build"
    }
  },

  "frameworks": {
    "netcoreapp1.0": {
      "imports": [
        "dotnet5.6",
        "dnxcore50",
        "portable-net45+win8"
      ]
    }
  },

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

  "runtimeOptions": {
    "gcServer": true
  },

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

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

Expected behavior

Restoring

Actual behavior

Throws the following error message: Package Microsoft.Composition 1.0.27 is not compatible with netcoreapp1.0 (.NETCoreApp,Version=v1.0). Package Microsoft.Composition 1.0.27 supports: portable-net45+win8+wp8+wpa81 (.NETPortable,Version=v0.0,Profile=Profile259) One or more packages are incompatible with .NETCoreApp,Version=v1.0.

Edit I added the package from the Visual Studio “Quick Fix” menu

After upgrading to VS2017 and therefore downgrading to XML I had to add it to my .csproj file like this:

<PropertyGroup>    
  <TargetFramework>netcoreapp1.1</TargetFramework>
  <PackageTargetFallback>$(PackageTargetFallback);portable-win+net45+wp8+win81+wpa8</PackageTargetFallback>
</PropertyGroup>

Just adding this here for others who come across this issue here. I managed to resolve the issue by adding "net451" to the imports section of my netcoreapp1.1 framework dedendency of my package.json file.

My particular package.json file looked like this.

{
  "version": "1.0.0-*",
  "buildOptions": {
    "debugType": "portable",
    "emitEntryPoint": true
  },
  "dependencies": {
    "Microsoft.VisualStudio.Web.CodeGeneration.Tools": {
      "version": "1.1.0-preview4-final",
      "type": "build"
    },
    "Microsoft.VisualStudio.Web.CodeGenerators.Mvc": {
      "version": "1.1.0-preview4-final",
      "type": "build"
    },
    "Microsoft.AspNetCore.Mvc": "1.0.0-*",
    "Microsoft.AspNetCore.StaticFiles": "1.0.0-*"
  },
  "tools": {
    "Microsoft.AspNetCore.Server.IISIntegration.Tools": "1.1.0-preview4-final",
    "Microsoft.EntityFrameworkCore.Tools": "1.1.0-preview4-final",
    "Microsoft.VisualStudio.Web.CodeGeneration.Tools": {
      "version": "1.1.0-preview4-final",
      "imports": [
        "portable-net45+win8"
      ]
    }
  },
  "frameworks": {
    "netcoreapp1.1": {
      "dependencies": {
        "Microsoft.NETCore.App": {
          "type": "platform",
          "version": "1.1.0"
        }
      },
      "imports": [
        "netcoreapp1.1",
        "net451"
      ]
    }
  }
}

The problem is most likely the tool “Microsoft.VisualStudio.Web.CodeGeneration.Tools”. Add the imports to the section:

“Microsoft.VisualStudio.Web.CodeGeneration.Tools”: { “version”: “1.0.0-preview1-final”, “type”: “build”, “imports”: [ “portable-net45+win8+dnxcore50”, “portable-net45+win8” ] }

That dose not help.

@piotrpMSFT Having same issue when upgraded to .NET Core 1.1 and workaround above did not solve the issue.

radenkozec on Nov 28, 2016

fyi there is a breaking change coming in 2.0 - this is changing to be AssetTargetFallback (which .NET Core 2.0 apps have by default) and cannot be used together with PackageTargetFallback

@gitfortee The $() syntax is used to substitute with the value of a property. In this case, the PackageTargetFallback is extended by a part. (So if it was a before it will be a;portable-…)

I am encountering the same issue with core 1.1. The fix identified by @radenkozec didn’t work.
