Asp.Net核心2與ViewComponent和Redis問題

我正在玩基本的應用程序，我遇到了核心2.0的問題，我沒有在1.1中。Asp.Net核心2與ViewComponent和Redis問題

該網站在Core 2.0上都有前端和後端api。前端的佈局檢查Redis上是否存在條目（Windows上的本地安裝）用於填充導航欄，如果不是，則調用api，api獲取數據，使用數據在redis上創建條目，並將數據返回到前端。直接訪問視圖時

一切工作正常，但如果例如視圖使用一個

return RedirectToAction("Blah2");

重定向工作正常，但是服務器掛起時，如果存在導航欄條目的viewcomponent正在檢查在Redis。的意見是：

[HttpGet] 
public IActionResult Blah1() 
{ 
    return RedirectToAction("Blah2"); 
} 

[HttpGet] 
public IActionResult Blah2() 
{ 
    return View(); 
}

視圖組件Redis的支票是

var value = await _redisCache.GetAsync(userid + "-NavBar"); 

if (value != null) 
{ 
    List<VMNavBar> mynavs = JsonConvert.DeserializeObject<List<VMNavBar>>(Encoding.UTF8.GetString(value)); 
    return View("Default", mynavs); 
} 
else 
{ 
    ... 
}

如果我訪問視圖「Blah2」直接它的工作原理，但如果我訪問「Blah1」，它的塊上var value = await _redisCache.GetAsync（userid +「-NavBar」）;除了停止並重新啓動前端應用程序，沒有任何工作。

爲什麼它會阻止只要重定向，或者我怎麼能找到它爲什麼塊，我沒有得到任何錯誤，控制檯不給我任何東西

，我發現它和我做的任何想法不明白爲什麼它是這個問題，如果我直接進入它的工作頁面，但不是如果我被重定向到另一個頁面。

我不得不改變

var value = await _redisCache.GetAsync(userid + "-NavBar");

到

var value = await _redisCache.Get(userid + "-NavBar");

在視圖分量，種笨就這個框。
