入口點在裝配沒有發現「Microsoft.EntityFrameworkCore.Design，版本= 1.1.0.0

我得到一個類似的問題，這個帖子：入口點在裝配沒有發現「Microsoft.EntityFrameworkCore.Design，版本= 1.1.0.0

Entry point not found in assembly 'Microsoft.EntityFrameworkCore.Design - dotnet.exe crashes

我已經創建了一個Asp.Net核心MVC應用程序和project.json看起來是這樣的：

我已經嘗試了一堆東西，但不能設置命令：「DOTNET EF數據庫更新-c IdentityDb」在命令窗口中工作（IdentityDb替換默認應用上下文）。只是不斷崩潰說：在程序集中找不到入口點'Microsoft.EntityFrameworkCore.Design，版本= 1.1.0.0

您是否碰巧找到解決方案？當我嘗試運行這個時，確切的事情正在發生。 – BHubbard

我跑了同樣的問題，經過幾次測試，我找到了解決方案。這裏我project.json

"dependencies": { 
"Microsoft.AspNetCore.Authentication.Cookies": "1.1.1", 
"Microsoft.AspNetCore.Diagnostics": "1.1.1", 
"Microsoft.AspNetCore.Diagnostics.EntityFrameworkCore": "1.1.1", 
"Microsoft.AspNetCore.Identity.EntityFrameworkCore": "1.1.1", 
"Microsoft.AspNetCore.Mvc": "1.1.2", 
"Microsoft.AspNetCore.Routing": "1.1.1", 
"Microsoft.AspNetCore.Server.IISIntegration": "1.1.1", 
"Microsoft.AspNetCore.Server.Kestrel": "1.1.1", 
"Microsoft.AspNetCore.StaticFiles": "1.1.1", 
"Microsoft.EntityFrameworkCore.SqlServer": "1.1.1", 
"Microsoft.EntityFrameworkCore.SqlServer.Design": "1.1.1", 
"Microsoft.EntityFrameworkCore.Design": "1.1.1", 
"Microsoft.EntityFrameworkCore.Tools.DotNet": "1.1.0-preview4-final", 
"Microsoft.Extensions.Configuration.EnvironmentVariables": "1.1.1", 
"Microsoft.Extensions.Configuration.Json": "1.1.1", 
"Microsoft.Extensions.Configuration.UserSecrets": "1.1.1", 
"Microsoft.Extensions.Logging": "1.1.1", 
"Microsoft.Extensions.Logging.Console": "1.1.1", 
"Microsoft.Extensions.Logging.Debug": "1.1.1", 
"Microsoft.Extensions.Options.ConfigurationExtensions": "1.1.1", 
"Microsoft.VisualStudio.Web.BrowserLink.Loader": "14.1.0", 
"Microsoft.VisualStudio.Web.CodeGeneration.Tools": "1.1.0-preview4-final", 
"Microsoft.VisualStudio.Web.CodeGenerators.Mvc": "1.1.0", 
"Microsoft.NETCore.App": "1.1.1"}, 

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

"frameworks": { 
"netcoreapp1.1": { 
    "imports": [ 
    "dotnet5.6", 
    "portable-net45+win8"]}}, 

"tools": { 
"Microsoft.AspNetCore.Server.IISIntegration.Tools": "1.0.0-preview2-final", 
"Microsoft.VisualStudio.Web.CodeGeneration.Tools": { 
    "version": "1.1.0-preview4-final", 
    "imports": [ 
    "portable-net45+win8" 
    ] 
}, 
"Microsoft.EntityFrameworkCore.Tools.DotNet": "1.1.0-preview4-final"}

爲了得到它解決了，你應該升級到.NET 1.1的核心

在依賴改變Microsoft.NETCore.App到1.1.1，並在框架部分的netcoreapp1。 0引用將需要改變，以netcoreapp1.1

重要：這些工具包的名稱已經從Microsoft.EntityFrameworkCore.Tools改爲Microsoft.EntityFrameworkCore.Tools.Dotnet

請同時參閱這http://bencoleman.co.uk/dotnet-core-1-1-gotchas/

我也升級的NuGet 3.5 Nuget

我希望的版本，它會幫助你。親切的問候
