Can you confirm which version of Visual Studio 2022 do you have? It needs to be 17.8.0 or later.

@masteroleary Ok, so your VS version is fine. Can you open a command prompt window and tell us what dotnet --info returns?

@masteroleary thanks for the information so far. it seems you're running this on Parallels on a mac, correct? I wonder if in your case it might be an issue with the PATH. Can you check what where.exe dotnet returns? Maybe you need to change the order like I show at https://github.com/dotnet/core/issues/5962#issuecomment-780084535

I'd also try the CLI version to see if there's a mismatch between what you're running on the terminal and VS. Can you run the command from https://dotnet.microsoft.com/en-us/learn/aspnet/blazor-cli-tutorial/create just fine?

masteroleary commented 8 months ago

Yes, Parallels on Mac

where.exe dotnet C:\Program Files\dotnet\dotnet.exe

$ dotnet new blazor -o BlazorApp The template "Blazor Web App" was created successfully. This template contains technologies from parties other than Microsoft, see https://aka.ms/aspnetcore/8.0-third-party-notices for details.

@masteroleary I checked with the team and they recommended you turn tracing on

Open a developer command prompt and set the following environment variables SET VS_WTE_DIAGNOSTIC_MODE=File SET VS_WTE_DIAGNOSTIC_VERBOSITY=2 SET VS_WTE_DIAGNOSTIC_TRACESWITCHES=ALL SET VS_WTE_DIAGNOSTIC_OUTPUTFILE=%temp%\wte.log

  1. Launch VS from the prompt using devenv.exe
  2. Do File/New Project so you'll go through the new project dialog
  3. Send us the log from %temp%\wte.logor share it, but scrub things like user names from the path

Tracing will log how the template engine is resolving .NET templates, including those coming from optional workloads.

VS is picking up the templates from Program Files\dotnet\x64. That is used by the x64 copy of dotnet on arm64 machines, and it's picking up older 7.0.9 templates from there.

Are you running an x64 copy of Visual Studio on arm64 Windows?

Yes, you are right! I deleted the x64 versions and restarted. Now the template appears in visual studio. Thank you @joeloff and @mairaw so much!

joeloff commented 8 months ago

Awesome, happy to help.

mairaw commented 8 months ago

Thanks @joeloff for taking us to the finish line!

@Pawan1718 the original issue is from you and your case is probably different than @masteroleary. So please let us know if you can confirm which version of VS you're running.
