在ASP.NET 5中显示错误信息

在 ASP.NET 5 中如果不进行显示错误信息的相关配置,在发生错误时,在浏览器中只能看到空白页面。

显示错误信息的配置方法如下:

1)在 project.json 中添加对 Microsoft.AspNet.Diagnostics 的引用

{
    "dependencies":{
        "Microsoft.AspNet.Diagnostics": "1.0.0-*"
    }
}

2)在 Startup.cs 中添加 app.UseErrorPage() 

public class Startup
{
    public void Configure(IApplicationBuilder app)
    {
        app.UseErrorPage();
    }
}

错误信息显示页面示例:

An error occurred during the compilation of a resource required to process this request. Please review the following specific error details and modify your source code appropriately.

/Views/Shared/_Layout.cshtml

'IHtmlHelper<dynamic>' does not contain a definition for 'TabLink' and the best extension method overload 'HtmlHelperExtensions.TabLink(HtmlHelper, string, string, string)' requires a receiver of type 'HtmlHelper'
