Visual Studio 2019 在哪里可以找到 .net core 3.1 的 WebAssembly 模板

Question

I'm using very latest (16.4.2, dated 8th Jan 2020) Visual Studio 2019.

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.

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:

dotnet new -i Microsoft.AspNetCore.Blazor.Templates::3.1.0-preview2.19528.8

(found via Missing visual studio 2019 blazor webassembly app template )

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.

Any idea how I get the latest template rather than random searching and use .net core 3.1?

If there is a better way, can anyone let me know how to uninstall templates as I failed to find out how.

Answer 1

Run the following in a CLI or in Tools -> Nuget package Manager -> Package Manager Console:

dotnet new --install Microsoft.AspNetCore.Components.WebAssembly.Templates::3.2.0-preview3.20168.3

The NuGet package for above is here .
