asp.net core 1.1 项目升级至 asp.net core 2.0 preview 2
這兩天把一個 asp.net core 1.1 的項目遷移到了 asp.net core 2.0 preview 2 ,在這篇隨筆中記錄一下。?
如果項目在有 global.json 文件,需要刪除或修改為 .net 2.0 preview 2 的 sdk 版本號。
對于類庫項目的 .csproj,需要把 TagetFramework 改為?netstandard2.0 ,比如
<PropertyGroup><TargetFramework>netstandard1.6</TargetFramework> <AssemblyName>CNBlogs.Identity.ServiceAgent</AssemblyName><PackageId>CNBlogs.Identity.ServiceAgent</PackageId> <NetStandardImplicitPackageVersion>1.6.1</NetStandardImplicitPackageVersion> <GenerateAssemblyConfigurationAttribute>false</GenerateAssemblyConfigurationAttribute> <GenerateAssemblyCompanyAttribute>false</GenerateAssemblyCompanyAttribute> <GenerateAssemblyProductAttribute>false</GenerateAssemblyProductAttribute></PropertyGroup>
改為
<PropertyGroup><TargetFramework>netstandard2.0</TargetFramework></PropertyGroup>對于單元測試項目,TargetFramework 需要改為?netcoreapp2.0 ,比如
<PropertyGroup><TargetFramework>netcoreapp1.1</TargetFramework><AssemblyName>CNBlogs.Identity.UnitTests</AssemblyName><PackageId>CNBlogs.Identity.UnitTests</PackageId> <GenerateRuntimeConfigurationFiles>true</GenerateRuntimeConfigurationFiles> <RuntimeFrameworkVersion>1.1.1</RuntimeFrameworkVersion> <GenerateAssemblyConfigurationAttribute>false</GenerateAssemblyConfigurationAttribute> <GenerateAssemblyCompanyAttribute>false</GenerateAssemblyCompanyAttribute> <GenerateAssemblyProductAttribute>false</GenerateAssemblyProductAttribute></PropertyGroup>改為
<PropertyGroup><TargetFramework>netcoreapp2.0</TargetFramework></PropertyGroup>對于 web 項目,需要該動的地方很多。除了把?TargetFramework 改為?netcoreapp2.0 ,比如
<PropertyGroup><TargetFramework>netcoreapp1.1</TargetFramework> <PreserveCompilationContext>true</PreserveCompilationContext><AssemblyName>CNBlogs.Identity.Web</AssemblyName><OutputType>Exe</OutputType><PackageId>CNBlogs.Identity.Web</PackageId><RuntimeIdentifiers>win10-x64;win8-x64;osx.10.12-x64;ubuntu.14.04-x64</RuntimeIdentifiers> <PackageTargetFallback>$(PackageTargetFallback);dnxcore50;portable-net45+win10</PackageTargetFallback> <RuntimeFrameworkVersion>1.1.1</RuntimeFrameworkVersion></PropertyGroup>改為
<PropertyGroup><TargetFramework>netcoreapp2.0</TargetFramework></PropertyGroup>還需要:
1)移除所有對 Microsoft.AspNetCore 的引用
<PackageReference Include="Microsoft.AspNetCore.Authentication" Version="1.1.2" /><PackageReference Include="Microsoft.AspNetCore.Authentication.Cookies" Version="1.1.2" /><PackageReference Include="Microsoft.AspNetCore.DataProtection.Extensions" Version="1.1.2" /><PackageReference Include="Microsoft.AspNetCore.DataProtection.Redis" Version="0.1.2" /><PackageReference Include="Microsoft.AspNetCore.Diagnostics" Version="1.1.2" /><PackageReference Include="Microsoft.AspNetCore.Hosting" Version="1.1.2" /><PackageReference Include="Microsoft.AspNetCore.Mvc" Version="1.1.3" /><PackageReference Include="Microsoft.AspNetCore.Mvc.Razor.ViewCompilation" Version="1.1.1" /><PackageReference Include="Microsoft.AspNetCore.Server.IISIntegration" Version="1.1.2" /><PackageReference Include="Microsoft.AspNetCore.Server.Kestrel" Version="1.1.2" /><PackageReference Include="Microsoft.AspNetCore.Session" Version="1.1.2" /><PackageReference Include="Microsoft.AspNetCore.StaticFiles" Version="1.1.2" />添加 Microsoft.AspNetCore?的引用
<PackageReference Include="Microsoft.AspNetCore.All" Version="2.0.0-preview2-final" />2)修改?Authentication 相關的代碼
CookieAuthenticationOptions 的命名空間改為?Microsoft.AspNetCore.Authentication.Cookies
HttpContext.Authentication.SignInAsync() 改為?HttpContext.SignInAsync() ,需要安裝 NuGet 包?Microsoft.AspNetCore.Authentication.Abstractions ,引用命名空間?Microsoft.AspNetCore.Authentication 。?
cookieAuthOptions.Value.AuthenticationScheme 改為?CookieAuthenticationDefaults.AuthenticationScheme
3) 針對?BundlerMinifier 的修改
在 asp.net core 2.0 preview 2 的 docker ?容器中 build 項目,在執行 dotnet bundle 時出現下面的錯誤
It was not possible to find any compatible framework version The specified framework 'Microsoft.NETCore.App', version '1.1.0' was not found. - Check application dependencies and target a framework version installed at:/ - Alternatively, install the framework version '1.1.0'.這是由于 nuget 包 BundlerMinifier.Core?不支持 .net core 2.0 。github 上簽出?BundlerMinifier?的源碼(已增加了對.net core 2.0的支持),自己打包。?
升級時不僅要升級?PackageReference 中的?BundlerMinifier.Core ,還要升級?DotNetCliToolReference 中的?BundlerMinifier.Core 。
4)針對?DataProtection 的修改
Microsoft.AspNetCore.DataProtection.Redis 的?PersistKeysToRedis() 方法不起作用,需要改用臨時解決方法:
services.Configure<KeyManagementOptions>(o =>{o.XmlRepository = new RedisXmlRepository(() => redisConn.GetDatabase(), "DataProtection-Keys-Cnblogs"); });詳見?PersistKeysToRedis not working in .NET Core 2.0 Preview 2 with Redis 0.1.2
5)Startup 的修改
去除構造函數中下面的代碼
var builder = new ConfigurationBuilder() ? ?.SetBasePath(env.ContentRootPath) ? ?.AddJsonFile("appsettings.json", optional: true, reloadOnChange: true) ? ?.AddJsonFile($"appsettings.{env.EnvironmentName}.json", optional: true); builder.AddEnvironmentVariables(); Configuration = builder.Build();去除 Configure 方法中下面的代碼
loggerFactory.AddSerilog(); loggerFactory.AddConsole(Configuration.GetSection("Logging"));IConfigurationRoot 改為?IConfiguration
public Startup(IConfiguration configuration) {Configuration = configuration; }
public IConfiguration Configuration { get; set; }
6)Program 的修改
public class Program { ? ?? ?public static void Main(string[] args){BuildWebHost(args).Run();} ?
? ?public static IWebHost BuildWebHost(string[] args){ ? ? ? ?
? ? ? ?return WebHost.CreateDefaultBuilder(args).ConfigureLogging((context, logging) =>{logging.AddSerilog();}).UseStartup<Startup>().Build();} }
完成 web 項目升級后,升級所有 NuGet 包,刪除所有 AssemblyInfo.cs 文件,整個升級就完成了。
