Commands: .NET Core CLI Implementation

DNX commands will be going away with the transition to .NET Core CLI. We’ll need to create a .NET Core CLI tools package instead. Like the NuGet PMC commands, any version of the command should be able to work with any version of the framework.

Known Issues

• System.DllNotFoundException: Unable to load DLL ‘sni.dll’: The specified module could not be found. (Exception from HRESULT: 0x8007007E) (#4953)
• Unable to load DLL ‘sqlite3’: The specified module could not be found. (Exception from HRESULT: 0x8007007E) (dotnet/cli#2289)
• Could not load file or assembly ‘System.Data.SqlClient, Version=4.1.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a’ or one of its dependencies. The system cannot find the file specified. (dotnet/cli#2289)
• Support netcoreapp1.0 apps
• Hosting environment not setup correctly. https://github.com/aspnet/EntityFramework/issues/5065
• Newtonsoft.Json 7.0.0 missing at runtime https://github.com/NuGet/Home/issues/2462
• Newtonsoft.Json 8.0.0 could not be loaded at runtime https://github.com/dotnet/cli/issues/2514. Workaround in #5082
• Tools using ConfigurationBuilder without setting basepath cannot find config files. won’t fix. User’s need to set base path to IHostingEnvironment.ContentRootPath.
• Need to change to nested-dispatch model because AssemblyLoadContext does not provide the necessary isolation https://github.com/dotnet/cli/issues/2514
• Cannot use dotnet-ef on a netstandard library or standalone app with nested-dispatch https://github.com/dotnet/cli/issues/2645

Usage

Your project.json should look something like this.

{
    "compilationOptions": {
        "emitEntryPoint": true
    },
    "tools": {
        "Microsoft.EntityFrameworkCore.Tools": { 
            "version": "1.0.0-*",
            "imports": "portable-net452+win81"
         }
    },
    "dependencies": {
        "Microsoft.EntityFrameworkCore.Sqlite": "1.0.0-*",
        "Microsoft.EntityFrameworkCore.Sqlite.Design": { "version": "1.0.0-*", "type": "build" },

        "Microsoft.EntityFrameworkCore.Tools": { "version": "1.0.0-*", "type": "build" }
    },
    "frameworks": {
        "netcoreapp1.0": {
            "imports": "portable-net452+win81",
            "dependencies": {
                "Microsoft.NETCore.App": { 
                     "version": "1.0.0-*",
                     "type": "platform"
                 }
            }
        }
    }
}

Your workflow will look something like this.

dotnet restore
cd src\MyProject
dotnet ef migrations add MyMigration
dotnet ef database update

Blocked on https://github.com/dotnet/cli/issues/2289. The issue: sqlite3.dll and sni.dll are not included in the AssemblyLoadContext, so any calls to actually connect to the database fail.

Might just be the TFM change, but latest cli doesn’t even find dotnet-ef. 😢
