问题描述
我正在使用最新的Visual Studio 2019(16.4.2，日期为2020年1月8日).
I'm using very latest (16.4.2, dated 8th Jan 2020) Visual Studio 2019.
当我尝试创建Blazor WebAssembly解决方案时，尽管"blazor app"的描述中包含"server or webassembly"一词，但是当我进入创建页面时，只有"Server"选项可用，并且它成功创建了Core 3.1应用程序
When I tried to create a Blazor WebAssembly solution, although the description for 'blazor app' included the words 'server or webassembly', when I got to the create page, only Server option was available and it successfully creates Core 3.1 application.
我以为会有最新版本，所以我去了Visual Studio市场网站，没有找到Blazor扩展，因此在Internet上我发现运行此命令:
I assumed latest version would be there, so I went to the Visual Studio marketplace website and there were no Blazor extensions to be found, so looking on the internet I found running this command:
(通过找到缺少的Visual Studio 2019 blazor webassembly应用模板
(found via Missing visual studio 2019 blazor webassembly app template)
它奏效了，我有了Web程序集选项.但是，当我查看使用WebAssembly创建的项目时，它使用的是.net Core 2.0，而选项最多只能显示2.1.我以"3.1.0"部分为准，这将是最新的名称.
And it worked, I got web assembly option. However, when I look at my project created using WebAssembly it is using .net Core 2.0 and the options only go as far as 2.1. I presumed by the '3.1.0' section in the name it would be the latest.
有人知道我如何获得最新的模板，而不是随机搜索并使用.net core 3.1吗?
Any idea how I get the latest template rather than random searching and use .net core 3.1?
如果有更好的方法，有人找不到我怎么能让我知道如何卸载模板.
If there is a better way, can anyone let me know how to uninstall templates as I failed to find out how.
