我将我的ASP.NET 1.1项目迁移到2.0：

I'm migrating my ASP.NET 1.1 project to 2.0:

在 Setup 类内， Configure 方法覆盖了我

Inside the Setup class, under the Configure method override I have:

services.AddMvc() .AddJsonOptions(options => options.SerializerSettings.Converters.Add(new StringEnumConverter()) );

缺少 AddJsonOptions 方法。

发生了什么事？如何获得相同的功能？

What happened to it? How can I get the same functionality?

推荐答案

AddJsonOptions 在 Microsoft.AspNetCore.Mvc.Formatters.Json nuget程序包。

AddJsonOptions is defined in Microsoft.AspNetCore.Mvc.Formatters.Json nuget package.

如果您的项目依赖于 Microsoft.AspNetCore.All 元包（在您的.csproj中：< PackageReference Include = Microsoft.AspNetCore.All Version = 2.0.0 /> ），那么您已经拥有了它。否则，您可能需要直接添加该软件包。

If your project has a dependency to Microsoft.AspNetCore.All metapackage (in your .csproj: <PackageReference Include="Microsoft.AspNetCore.All" Version="2.0.0"/> ) then you already have it. Otherwise, you may need to add that package directly.

之后，请执行以下操作：

After that do:

• dotnet恢复
• 使用Microsoft.Extensions.DependencyInjection检查您是否具有；

• dotnet restore
• check that you have using Microsoft.Extensions.DependencyInjection;
