System.InvalidOperationException：當前運行時目標框架與「項目」不兼容

我使用1.0.0啓動了一個新的ASP.NET項目。我可以建立並運行該項目很好，但是當我嘗試運行實體框架指令在開發商命令提示符（我一直在用「DNX EF」測試），我收到以下錯誤：System.InvalidOperationException：當前運行時目標框架與「項目」不兼容

System.InvalidOperationException: The current runtime target framework is not compatible with 'myprojectname'

我在堆棧溢出的其他地方找不到解決方案。當項目無法建立或運行時，大多數問題似乎都有助於解決問題，這不是問題。這裏是我的project.json的相關部分：

"dependencies": { 
    "Microsoft.AspNetCore.Authentication.Cookies": "1.0.0", 
    "Microsoft.AspNetCore.Diagnostics": "1.0.0", 
    "Microsoft.AspNetCore.Diagnostics.EntityFrameworkCore": "1.0.0", 
    "Microsoft.AspNetCore.Identity.EntityFrameworkCore": "1.0.0", 
    "Microsoft.AspNetCore.Mvc": "1.0.0", 
    "Microsoft.AspNetCore.Razor.Tools": { 
     "version": "1.0.0-preview2-final", 
     "type": "build" 
    }, 
    "Microsoft.AspNetCore.Server.IISIntegration": "1.0.0", 
    "Microsoft.AspNetCore.Server.Kestrel": "1.0.0", 
    "Microsoft.AspNetCore.StaticFiles": "1.0.0", 
    "Microsoft.EntityFrameworkCore.SqlServer": "1.0.0", 
    "Microsoft.EntityFrameworkCore.SqlServer.Design": { 
     "version": "1.0.0", 
     "type": "build" 
    }, 
    "Microsoft.EntityFrameworkCore.Tools": { 
     "version": "1.0.0-preview2-final", 
     "type": "build" 
    }, 
    "Microsoft.Extensions.Configuration.EnvironmentVariables": "1.0.0", 
    "Microsoft.Extensions.Configuration.Json": "1.0.0", 
    "Microsoft.Extensions.Configuration.UserSecrets": "1.0.0", 
    "Microsoft.Extensions.Logging": "1.0.0", 
    "Microsoft.Extensions.Logging.Console": "1.0.0", 
    "Microsoft.Extensions.Logging.Debug": "1.0.0", 
    "Microsoft.Extensions.Options.ConfigurationExtensions": "1.0.0", 
    "Microsoft.VisualStudio.Web.BrowserLink.Loader": "14.0.0", 
    "Microsoft.VisualStudio.Web.CodeGeneration.Tools": { 
     "version": "1.0.0-preview2-final", 
     "type": "build" 
    }, 
    "Microsoft.VisualStudio.Web.CodeGenerators.Mvc": { 
     "version": "1.0.0-preview2-final", 
     "type": "build" 
    } 
    }, 

    "tools": { 
    "BundlerMinifier.Core": "2.0.238", 
    "Microsoft.AspNetCore.Razor.Tools": "1.0.0-preview2-final", 
    "Microsoft.AspNetCore.Server.IISIntegration.Tools": "1.0.0-preview2-final", 
    "Microsoft.EntityFrameworkCore.Tools": "1.0.0-preview2-final", 
    "Microsoft.Extensions.SecretManager.Tools": "1.0.0-preview2-final", 
    "Microsoft.VisualStudio.Web.CodeGeneration.Tools": { 
     "version": "1.0.0-preview2-final", 
     "imports": [ 
     "portable-net45+win8" 
     ] 
    } 
    }, 

    "frameworks": { 
    "net461": { } 
    },

而且我global.json：

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

這裏是全力輸出，當我運行「DNX EF」：

System.InvalidOperationException: The current runtime target framework is not compatible with 'myprojectname'. 
Current runtime target framework: 'DNX,Version=v4.5.1 (dnx451)' 
Version:  1.0.0-rc1-16609 
Type:   Clr 
Architecture: x86 
OS Name:  Windows 
OS Version: 10.0 
Runtime Id: win10-x86 

Please make sure the runtime matches a framework specified in project.json 
    at Microsoft.Dnx.ApplicationHost.DefaultHost.GetEntryPoint(String applicationName) 
    at Microsoft.Dnx.ApplicationHost.Program.ExecuteMain(DefaultHost host, String applicationName, String[] args) 
    at Microsoft.Dnx.ApplicationHost.Program.Main(String[] args) 
--- End of stack trace from previous location where exception was thrown --- 
    at System.Runtime.ExceptionServices.ExceptionDispatchInfo.Throw() 
    at Microsoft.Dnx.Runtime.Common.EntryPointExecutor.Execute(Assembly assembly, String[] args, IServiceProvider serviceProvider) 
    at Microsoft.Dnx.Host.Bootstrapper.RunAsync(List`1 args, IRuntimeEnvironment env, String appBase, FrameworkName targetFramework) 
    at Microsoft.Dnx.Host.RuntimeBootstrapper.ExecuteAsync(String[] args, BootstrapperContext bootstrapperContext) 
    at Microsoft.Dnx.Host.RuntimeBootstrapper.Execute(String[] args, BootstrapperContext bootstrapperContext)

我需要做什麼才能讓EF運行遷移？這一直在驅使我瘋狂。

dnx和命令離開後RC1你應該使用dotnet ef

啊，謝謝！我已經退出ASP.NET 5循環以獲得一些測試版。 –
