这两天把一个 asp.net core 1.1 的项目迁移到了 asp.net core 2.0 preview 2 ，在这篇随笔中记录一下。
如果项目在有 global.json 文件，需要删除或修改为 .net 2.0 preview 2 的 sdk 版本号。
对于类库项目的 .csproj，需要把 TagetFramework 改为 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>
改为
<PropertyGroup> <TargetFramework>netstandard2.0</TargetFramework> </PropertyGroup>
对于单元测试项目，TargetFramework 需要改为 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>
改为
<PropertyGroup> <TargetFramework>netcoreapp2.0</TargetFramework> </PropertyGroup>
对于 web 项目，需要该动的地方很多。除了把 TargetFramework 改为 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>
改为
<PropertyGroup> <TargetFramework>netcoreapp2.0</TargetFramework> </PropertyGroup>
还需要：
1）移除所有对 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 相关的代码
3） 针对 BundlerMinifier 的修改
在 asp.net core 2.0 preview 2 的 docker 容器中 build 项目，在执行 dotnet bundle 时出现下面的错误
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‘.
这是由于 nuget 包 BundlerMinifier.Core 不支持 .net core 2.0 。github 上签出 BundlerMinifier 的源码（已增加了对.net core 2.0的支持），自己打包。
升级时不仅要升级 PackageReference 中的 BundlerMinifier.Core ，还要升级 DotNetCliToolReference 中的 BundlerMinifier.Core 。
4）针对 DataProtection 的修改
Microsoft.AspNetCore.DataProtection.Redis 的 PersistKeysToRedis() 方法不起作用，需要改用临时解决方法：
services.Configure<KeyManagementOptions>(o => { o.XmlRepository = new RedisXmlRepository(() => redisConn.GetDatabase(), "DataProtection-Keys-Cnblogs"); });
详见 PersistKeysToRedis not working in .NET Core 2.0 Preview 2 with Redis 0.1.2
5）Startup 的修改
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();
loggerFactory.AddSerilog();
loggerFactory.AddConsole(Configuration.GetSection("Logging"));
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 项目升级后，升级所有 NuGet 包，删除所有 AssemblyInfo.cs 文件，整个升级就完成了。
asp.net core 1.1 项目升级至 asp.net core 2.0 preview 2
