Issues "getting started" with Blazor

Question

I'm trying to "get started" with Blazorfollowing Microsoft's guidelines,

I've installed the .NET Core 3.0 Preview SDK as indicated, but then I try to run the command

dotnet new -i Microsoft.AspNetCore.Blazor.Templates::3.0.0-preview5-19227-01

respectively from terminal and powershell both as admin and not, getting this error:

Did you mean to run dotnet SDK commands? Please install dotnet SDK from:...

I proceeded anyway installing Visual Studio Preview (with Blazor Extension)

to be able to run the command form the Visual studio terminal, but I'm simply getting this error:

Command "dotnet" is not valid.

Looks like doesn't recognize the installed SDK (3.0 or previous),

any idea how can I solve the issue? thanks in advance

Answer 1

我想如果路径中有多个相同的可执行文件，那么它将无法解析您要调用的那个文件。

尝试在命令行中使用.NET Core 3.0 SDK dotnet.exe的完整路径，例如 "C:\Program Files\dotnet\dotnet.exe" new -i Microsoft.AspNetCore.Blazor.Templates::3.0.0-preview5-19227-01（如果不确定哪个版本，可以使用dotnet --version查找exe版本）
