ASP.NET Core MVC MiddlewareFilter例外は意味がありません

Question

現在、私はMiddlewareFilterを有効にするときにスローされた例外に問題があります。フィルタを追加するとすぐに、開発者の例外も無意味です（完全なスタックトレースがありません）。フィルター付き

services.AddMvc(options => options.Filters.Add(new MiddlewareFilterAttribute(typeof(MyFilter)))) 

public class MyFilter 
{ 
    public void Configure(IApplicationBuilder applicationBuilder, RequestLocalizationOptions options) 
    { 
     applicationBuilder.UseRequestLocalization(options); 
    } 
} 

スタックトレース：フィルタなし

だから、基本的に私は、フィルタを有効にする場合、例外を追跡することができませんでしだ。これを修正する方法はありますか？ （私はMiddlewareFiltersを使用する必要があります）

Answer 1

はMiddlewareFilterBuilder implementationをチェックした後、この動作を "期待" されるようになります...

// Ideally we want the experience of a middleware pipeline to behave the same as if it was registered, 
// in Startup. In this scenario an exception thrown in a middelware later in the pipeline gets propagated 
// back to earlier middleware. 
// So check if a later resource filter threw an exception and propagate that back to the middleware pipeline. 
if (!resourceExecutedContext.ExceptionHandled && resourceExecutedContext.Exception != null) 
{ 
    throw resourceExecutedContext.Exception; 
} 

あなたは

System.Exception: Test Exception 
      at Microsoft.AspNetCore.Mvc.Internal.MiddlewareFilterBuilder.<>c.<<BuildPipeline>b__8_0>d.MoveNext() 

の代わり

を参照してください理由を説明することは、

System.Exception: Test Exception 
    at MyProject.MyRepository.<Fetch>d__9.MoveNext() 

上記のコードはdevブランチにありますが、マスターブラnch in aspnet/Mvc repo ...

これはMVCレポの質問/問題の良い候補のようです。
