Question

我创建了一个新的Blazor WebAssembly项目，并刚刚向共享项目中的模型中的属性添加了[Display]属性：

using System;
using System.ComponentModel.DataAnnotations;

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

这需要引用System.ComponentModel.DataAnnotations.dll。但是当我这样做并在发布模式下按Build时，编译器会抛出此错误：

5>C:\Users\Ali\.nuget\packages\microsoft.aspnetcore.components.webassembly.build\3.2.1\targets\Blazor.MonoRuntime.targets(326,5): error : Unhandled exception.

我知道如果禁用链接功能，我可以通过该错误，但是我不想这样做，因为我想减小下载量。

Answer 1

我发现我不必引用System.ComponentModel.DataAnnotations.dll，而必须使用同名的Nuget包，并且当我使用Nuget包时，可以消除链接错误。

Blazor WASM：引用System.ComponentModel.DataAnnotations会导致发行版本上的链接失败
