Asp.Net核心2与ViewComponent和Redis问题

我正在玩基本的应用程序，我遇到了核心2.0的问题，我没有在1.1中。Asp.Net核心2与ViewComponent和Redis问题

该网站在Core 2.0上都有前端和后端api。前端的布局检查Redis上是否存在条目（Windows上的本地安装）用于填充导航栏，如果不是，则调用api，api获取数据，使用数据在redis上创建条目，并将数据返回到前端。直接访问视图时

一切工作正常，但如果例如视图使用一个

return RedirectToAction("Blah2");

重定向工作正常，但是服务器挂起时，如果存在导航栏条目的viewcomponent正在检查在Redis。的意见是：

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

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

视图组件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 
{ 
    ... 
}

如果我访问视图“Blah2”直接它的工作原理，但如果我访问“Blah1”，它的块上var value = await _redisCache.GetAsync（userid +“-NavBar”）;除了停止并重新启动前端应用程序，没有任何工作。

为什么它会阻止只要重定向，或者我怎么能找到它为什么块，我没有得到任何错误，控制台不给我任何东西

，我发现它和我做的任何想法不明白为什么它是这个问题，如果我直接进入它的工作页面，但不是如果我被重定向到另一个页面。

我不得不改变

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

到

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

在视图分量，种笨就这个框。
