.NET Core單檔案釋出靜態編譯AOT CoreRT

dotNET跨平臺發表於2018-01-16

.NET Core單檔案釋出靜態編譯AOT CoreRT,將.NET Core應用打包成一個可執行檔案幷包含執行時。

支援Windows, MacOS and Linux x64 w/ RyuJIT codegen。

示例專案:

https://github.com/dotnet/corert/tree/master/samples/WebApi

下面來實際體驗。

首先確保安裝C++編譯環境,以及.NET Core 2.0 以上版本SDK。

新建WebAPI應用

開啟命令提示符,輸入如下:

dotnet new webapi -o zeroapi

cd zeroapi

新建WebAPI應用。

新增CoreRT到專案

目前CoreRT還是alpha版,在myget上有包。

首先新增一個nuget.config

dotnet new nuget

然後在 <packageSources> 節點新增如下:

<add key="dotnet-core" value="https://dotnet.myget.org/F/dotnet-core/api/v3/index.json" />
<add key="nuget.org" value="https://api.nuget.org/v3/index.json" protocolVersion="3" />

接著新增Microsoft.DotNet.ILCompiler包引用:

dotnet add package Microsoft.DotNet.ILCompiler -v 1.0.0-alpha-*

替換預設services並處理反射

開啟Startup.cs ,將 services.AddMvc(); 替換成 services.AddMvcCore().AddJsonFormatters();

接著建立一個rd.xml 配置檔案,用於反射處理執行時,確保反射程式集編譯到程式中。

rd.xml配置檔案如下:

<Directives>

            <Type Name="System.Linq.Expressions.ExpressionCreator`1[[System.Func`2[[System.Object,System.Private.CoreLib],[System.Object,System.Private.CoreLib]],System.Private.CoreLib]]" Dynamic="Required All" />

            <Type Name="Microsoft.Extensions.Configuration.Json.JsonConfigurationSource" Dynamic="Required All" />

        </Assembly>

    </Application>

</Directives>

其中如果你要替換成自己的程式,更改 <Assembly Name="zeroapi" Dynamic="Required All" /> 中的Name。

開啟zeroapi.csproj

在<PropertyGroup>節點下將 <RdXmlFile>rd.xml</RdXmlFile> 加入。

接著將 <PackageReference Include="Microsoft.AspNetCore.All" Version="2.0.3" /> 替換成如下:

<PackageReference Include="Microsoft.AspNetCore" Version="2.0.1" />

<PackageReference Include="Microsoft.AspNetCore.Mvc.Core" Version="2.0.1" />

<PackageReference Include="Microsoft.AspNetCore.Mvc.Formatters.Json" Version="2.0.1" />

 

接著將 ValuesController 更改一下,確保功能正常,如下:

public class ValuesController

    {

        [HttpGet("/")]

        public string Hello() => "Hello World! LineZero AOT";

        // GET api/values

        [HttpGet("/api/values")]

        public IEnumerable<string> Get()

        {

            return new string[] { "AOT", "CoreRT" };

        }

        // GET api/values/5

        [HttpGet("/api/values/{id}")]

        public string Get(int id)

        {

            return "Your value is " + id;

        }

    }

程式改造完成,接著最重要的釋出。

還原併發布

釋出之前,使用dotnet run 確保功能正常執行。

釋出請開啟 x64 Native Tools Command Prompt for VS 2017 ,注意一定在此命令列釋出。在開始選單找到 Visual Studio 2017,開啟就能找到。

釋出命令還是  dotnet publish -r <RID> -c <Configuration>

這裡釋出Windows 64位 dotnet publish -r win-x64 -c release,初次的話會預設還原對應的包,需要一些時間。

釋出完成後,開啟bin\x64\release\netcoreapp2.0\win-x64\publish 資料夾,裡面zeroapi.exe即為最終檔案,執行即可。

.NET Core單檔案釋出靜態編譯AOT CoreRT

 

可以看到最終大小為21m左右。然後訪問http://localhost:5000/ 如圖:

控制檯Demo

新建一個控制檯應用,使用AOT釋出。

單純控制檯,沒有反射的內容,無需要rd.xml 檔案。

程式碼如下:

class Program

    {

        static void Main(string[] args)

        {

            Console.WriteLine("Hello World!");

            Console.WriteLine("LineZero AOT Demo!");

            Console.ReadKey();

        }

    }

最終 dotnet publish -r win-x64 -c release 釋出

.NET Core單檔案釋出靜態編譯AOT CoreRT

最終單個檔案大小不到4m!

目前該技術還是早期版本,期待微軟最終帶到正式版。
