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

Question

Building a .net core mvc app in VS Code and getting the error IApplicationBuilder does not contain a definition for UseMvc. Here are my dependencies in my project.json:

"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

Looks like a goofed up dependency. Try changing this:

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

to this:

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

Answer 2

Add this PropertyGroup to projectName.csproj file:

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

Then close the solution and reopen it.
