我正在尝试创建一个新的ASP.net CORE应用程序，但问题是我构建的每个应用程序都出现以下错误消息：
PM> add-migration Init
System.IO.FileLoadException: Could not load file or assembly 'Microsoft.Extensions.Logging, Version=1.1.0.0, Culture=neutral, PublicKeyToken=adb9793829ddae60'. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

我用Google搜索并发现以下内容可能是错误。 Ref-Def-Mismatch https://blogs.msdn.microsoft.com/junfeng/2004/03/25/the-located-assemblys-manifest-definition-with-name-xxx-dll-does-not-match-the-assembly-reference/
只有我的问题是我无法找到解决此问题的方法。有没有人有想法？
我的project.json是：

像Daniel J.G.说我需要更新我的project.json以下内容：
{
"userSecretsId": "secret",
"runtimes": {
"win10-x64": {}
},
"dependencies": {
"Microsoft.AspNetCore.Razor.Tools": {
"version": "1.0.0-preview2-final",
"type": "build"
},
"Microsoft.EntityFrameworkCore.Tools": "1.1.0-preview4-final",
"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"
},
"Microsoft.ApplicationInsights.AspNetCore": "1.0.2",
"Microsoft.AspNetCore.Authentication.Cookies": "1.1.0",
"Microsoft.AspNetCore.Diagnostics": "1.1.0",
"Microsoft.AspNetCore.Diagnostics.EntityFrameworkCore": "1.1.0",
"Microsoft.AspNetCore.Identity.EntityFrameworkCore": "1.1.0",
"Microsoft.AspNetCore.Mvc": "1.1.0",
"Microsoft.AspNetCore.Routing": "1.1.0",
"Microsoft.AspNetCore.Server.IISIntegration": "1.1.0",
"Microsoft.AspNetCore.Server.Kestrel": "1.1.0",
"Microsoft.AspNetCore.StaticFiles": "1.1.0",
"Microsoft.EntityFrameworkCore.SqlServer": "1.1.0",
"Microsoft.EntityFrameworkCore.SqlServer.Design": "1.1.0",
"Microsoft.Extensions.Configuration.EnvironmentVariables": "1.1.0",
"Microsoft.Extensions.Configuration.Json": "1.1.0",
"Microsoft.Extensions.Configuration.UserSecrets": "1.1.0",
"Microsoft.Extensions.Logging": "1.1.0",
"Microsoft.Extensions.Logging.Console": "1.1.0",
"Microsoft.Extensions.Logging.Debug": "1.1.0",
"Microsoft.Extensions.Options.ConfigurationExtensions": "1.1.0",
"Microsoft.NETCore.App": "1.1.0",
"Microsoft.VisualStudio.Web.BrowserLink.Loader": "14.1.0"
},
"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": {
"netcoreapp1.1": {
"imports": [
"dotnet5.6",
"portable-net45+win8"
]
}
},
"buildOptions": {
"emitEntryPoint": true,
"preserveCompilationContext": true
},
"runtimeOptions": {
"configProperties": {
"System.GC.Server": true
}
},
"publishOptions": {
"include": [
"wwwroot",
"**/*.cshtml",
"appsettings.json",
"web.config"
]
},
"scripts": {
"prepublish": [ "bower install", "dotnet bundle" ],
"postpublish": [ "dotnet publish-iis --publish-folder %publish:OutputPath% --framework %publish:FullTargetFramework%" ]
}
}
之后我还需要指定我的deps.json。
PM> add-migration init
The specified deps.json [C:\Users\ik_ro\Source\Repos\ProjectDotNetCoreTest\src\ProjectDotNetCoreTest\bin\Debug\netcoreapp1.1\ProjectDotNetCoreTest.deps.json] does not exist
Process finished with non-zero exit code
PM> add-migration init
The specified framework 'Microsoft.NETCore.App', version '1.1.0' was not found.
- Check application dependencies and target a framework version installed at:
C:\Program Files\dotnet\shared\Microsoft.NETCore.App
- The following versions are installed:
1.0.1
- Alternatively, install the framework version '1.1.0'.
Process finished with non-zero exit code
它搜索的位置是：
C:\Users\ik_ro\Source\Repos\ProjectDotNetCoreTest\src\ProjectDotNetCoreTest\bin\Debug\netcoreapp1.1\win10-x64
但它必须是：
C:\Users\ik_ro\Source\Repos\ProjectDotNetCoreTest\src\ProjectDotNetCoreTest\bin\Debug\netcoreapp1.1\win10-x64
我将win10-x64文件夹中的所有内容复制并粘贴到netcoreapp1.1文件夹中。这解决了这个问题。
