带有 MVC iapplicationbuilder 的 ASP.NET Core 不包含 usemvc 的定义

Question

在 VS Code 中构建 .net core mvc 应用程序并收到错误 IApplicationBuilder 不包含 UseMvc 的定义。 这是我在 project.json 中的依赖项：

"dependencies": {
"Microsoft.NETCore.App": {
  "version": "1.0.1",
  "type": "platform"
},
"Microsoft.AspNetCore.Diagnostics": "1.0.0",
"Microsoft.AspNet.Mvc": "6.0.0-rc1-final",
"Microsoft.AspNetCore.Server.IISIntegration": "1.0.0",
"Microsoft.AspNetCore.Server.Kestrel": "1.0.1",
"Microsoft.Extensions.Logging.Console": "1.0.0",
"Microsoft.Extensions.Configuration.EnvironmentVariables": "1.0.0",
"Microsoft.Extensions.Configuration.FileExtensions": "1.0.0",
"Microsoft.Extensions.Configuration.Json": "1.0.0",
"Microsoft.Extensions.Configuration.CommandLine": "1.0.0",
"Microsoft.Extensions.DependencyInjection": "1.0.0",
"Microsoft.Extensions.DependencyInjection.Abstractions": "1.0.0",
"Microsoft.AspNetCore.StaticFiles": "1.0.0"

}

Answer 1

看起来像一个愚蠢的依赖。 尝试改变这个：

"Microsoft.AspNet.Mvc": "6.0.0-rc1-final",

对此：

"Microsoft.AspNetCore.Mvc": "1.0.1",

Answer 2

将此 PropertyGroup 添加到 projectName.csproj 文件：

<PropertyGroup>
   <PackageTargetFallback>$(PackageTargetFallback);portable-net45+win8+wp8+wpa81;
   </PackageTargetFallback>
</PropertyGroup>

然后关闭解决方案并重新打开它。
