.NETプラットフォーム間の旅:サンプルサイトをASP.にアップグレードしました.NET Core RC2

ASP.NET Core RC 2がついに発表された(Announcing ASP.NET Core RC 2).今回のリリースを祝うために、Ubuntuサーバ上のサンプルサイトaboutを実行します.cnblogs.comはASPにアップグレードしました.NET Core RC 2では、アップグレード中に発生した問題をこのブログで共有します.
一、取り付けNET Core SDK
旧版dotnet cliを削除するには:

rm -rf /usr/share/dotnet

インストールNET Core SDK:

curl -sSL https://raw.githubusercontent.com/dotnet/cli/rel/1.0.0/scripts/obtain/dotnet-install.sh | bash /dev/stdin --version 1.0.0-preview1-002702 --install-dir ~/dotnet

sudo ln -s ~/dotnet/dotnet /usr/local/bin

二、dotnet restoreコマンドの実行
2つのエラーが発生しました.
1) Unable to resolve 'Microsoft.AspNetCore.IISPlatformHandler (>= 1.0.0)' for '.NETCoreApp,Version=v1.0' 
解決方法:project.json中将Microsoft.AspNetCore.IISplatformHandlerをMicrosoftに変更しました.AspNetCore.Server.IISIntegration .
2) Package Newtonsoft.Json 7.0.1 is not compatible with netcoreapp1.0 (.NETCoreApp,Version=v1.0) 
解決方法:project.json中将

"tools": {
    "Microsoft.AspNetCore.Server.IISIntegration.Tools": "1.0.0-*"
}

に改心

"tools": {
    "Microsoft.AspNetCore.Server.IISIntegration.Tools":{
        "version":"1.0.0-*",
        "imports": "portable-net45+win8+dnxcore50"
    }
}

詳しくは博問を参照してください.http://q.cnblogs.com/q/82384/
三、dotnet runコマンドの実行
多くのエラーが発生しました.
1)

The type or namespace name 'IApplicationEnvironment' could not be found (are you missing a using directive or an assembly reference?)

解決方法:Startup.csのIApplicationEnvironmentをIHostingEnvironmentに変更しました.詳細はhttp://q.cnblogs.com/q/82388/.
2)

'IWebHostBuilder' does not contain a definition for 'UseDefaultHostingConfiguration' and no extension method 'UseDefaultHostingConfiguration' accepting a first argument of type 'IWebHostBuilder' could be found (are you missing a using directive or an assembly reference?)

解決方法:Program.csで削除します.UseDefaultHostingConfiguration(args)
3)

'IWebHostBuilder' does not contain a definition for 'UseIISPlatformHandlerUrl' and no extension method 'UseIISPlatformHandlerUrl' accepting a first argument of type 'IWebHostBuilder' could be found

解決方法:Program.cs中将UseIISplatformHandlerUrl()をUseIISintegration()に変更
4)

'ConfigurationBuilder' does not contain a definition for 'SetBasePath' and no extension method 'SetBasePath' accepting a first argument of type 'ConfigurationBuilder' could be found

解決方法:project.jsonのdependenciesに構成を追加:「Microsoft.Extensions.Configuration.FileExtensions」:「1.0.0-*」を参照http://q.cnblogs.com/q/82391/
5)

'IConfigurationBuilder' does not contain a definition for 'AddJsonFile' and no extension method 'AddJsonFile' accepting a first argument of type 'IConfigurationBuilder' could be found

解決方法:project.jsonのdependenciesに構成を追加:「Microsoft.Extensions.Configuration.Json」:「1.0.0-*」を参照http://q.cnblogs.com/q/82395/
6)

The type or namespace name 'IRuntimeEnvironment' does not exist in the namespace 'Microsoft.Extensions.PlatformAbstractions' 

解決方法:Layout.cshtmlから@inject Microsoftを削除します.Extensions.PlatformAbstractions.IruntimeEnvironment env,ネーミングスペース@using Microsoftを追加.Extensions.PlatformAbstractionsとコード@{var env=PlatformServices.Default.Runtime;}です.
四、コードの改善
プログラムでcs中将UseServer(「Microsoft.AspNetCore.Server.Kestrel」)を.UseKestrel() .
五、プロジェクトjson、Program.cs、Startup.csの完全なコード
1)project.json

{
   "compilationOptions": {
        "preserveCompilationContext": true,

                        .UseContentRoot(Directory.GetCurrentDirectory())
                        .UseIISIntegration()
                        .UseStartup<Startup>()
                        .Build();
