Blazor WASM：引用 System.ComponentModel.DataAnnotations 导致发布版本链接失败

Question

我创建了一个新的 Blazor WebAssembly 项目，并刚刚在共享项目的模型中向属性添加了一个 [Display] 属性：

using System;
using System.ComponentModel.DataAnnotations;

public class WeatherForecast
{
    [Display(Name = "Temperature")]
    public int TemperatureC { get; set; }
    ...
}

这需要参考System.ComponentModel.DataAnnotations.dll。但是当我这样做然后在 Release 模式下按 Build 时，编译器会抛出这个错误：

5>C:\Users\Ali\.nuget\packages\microsoft.aspnetcore.components.webassembly.build.2.1\targets\Blazor.MonoRuntime.targets(326,5): error : Unhandled exception. Mono.Linker.MarkException: Error processing method: 'System.Void System.Configuration.ConfigurationErrorsException::.ctor(System.String,System.Exception,System.String,System.Int32)' in assembly: 'System.Configuration.dll'

我知道如果我禁用链接功能我可以通过错误，但我不想这样做因为我想减少下载的大小。

Answer 1

我发现我必须使用同名的 Nuget 包而不是引用 System.ComponentModel.DataAnnotations.dll，并且当我使用 Nuget 包时，链接错误已消除。
