votes

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),

enter image description here

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

Have you restarted since the install of the SDK? And have you checked that dotnet is in your system path? Though I suppose it may not need to be in the path if you're using the Visual Studio terminal. - Dillanm
I've restarted several times and in the environment variables I have not 1, not 2, but 3! dotnet: "c:\Program Files(x86)\dotnet\", "c:\Program Files\dotnet\" and "c:\Program Files\dotnet". I've added manually one of the last 2 I don't remember which one. [edit: problem still persist] - Francesco Iapicca
I imagine if you've got multiple of the same executable in your path then it can't resolve which one you're trying to call - try manually using the full path to the .NET Core 3.0 SDK dotnet.exe in a command line e.g. "c:\Program Files\dotnet\dotnet.exe" new -i Microsoft.AspNetCore.Blazor.Templates::3.0.0-preview5-19227-01 (you can use dotnet --version to find the version of the exe if you're unsure which is which) - Dillanm
@Dillanm it worked! you are awesome, thanks mate if you post it as an answer I'll accept it straight away - Francesco Iapicca
No worries, glad I could help :) - Dillanm
