问题描述
只是第一次尝试Blazor.使用默认的Blazor模板，我在MainLayout.cshtml中添加了ViewComponent调用:
Just trying Blazor out for the first time. With the default Blazor template, I added a ViewComponent call to the MainLayout.cshtml:
@await Component.InvokeAsync("HeaderComponent")
IntelliSense显示await只能在async方法中使用.
IntelliSense shows await can only be used in an async method.
我在Blazor视图中尝试了相同的结果.我在布局中的MVC应用程序中使用了该组件(通过<vc:header-component />).
I tried the same in a Blazor view—same result. I use the component in an MVC app in the layout (via <vc:header-component />).
所以我不确定这是否可行，或者不确定当前的Blazor或Visual Studio 2019限制.
So I'm not sure if this is possible, or just a current Blazor or Visual Studio 2019 limitation.
推荐答案
否，您不能在Blazor中使用ViewComponent.是的，这是一个限制，从某种意义上讲，您不能在Angular中使用ViewComponent.
No, you can't use ViewComponent in Blazor. And yes, this is a limitation, in the same sense you can't use ViewComponent in Angular.
为什么需要局部视图? Blazor中有组件无法满足的用例吗?
Why do you need a partial view ? Is there any use case in Blazor that components cannot satisfy ?
