Describe the bug

Blazor Web App Template is not available in .NET 8 RC2 for arm64 when creating a new project in Visual Studio 17.8.0 Preview 3 in a Parallels Windows VM in Mac arm64.

Update:

It seems on closer inspection that none of the .NET 8 templates are being installed. I have reinstalled Visual Studio Preview 5.0 multiple times as well as .NET 8 SDK 8.0.100-rc.2.

Expected Behavior

I expected to see Blazor Web App in the list of available templates. I have it on my

@wtgodbe Do you have any ideas about what might be causing this?

[wtgodbe]

I'm not sure, we didn't change anything with how that gets produced as far as I know - @marcpopMSFT @dsplaisted @vlada-shubina how do dotnet templates normally make it in to VS? Looks like this one's missing for arm64 in RC2

[joeloff]

We build the installers for all the templates and VS should be picking those up. If they're missing from VS, I'd expect them to be missing from the standalone installations as well.

@MiYanni and @joeloff are current owners for templating. Does the template show up in the dotnet CLI? We build the template msis and insert them into VS. You could collect new project logs and see if there's some error in there but if we have any templates, we should have them all unless there's something in the msi creation.
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

We use the same target for all platforms: https://github.com/dotnet/installer/blob/c5ce95b250cc405443c5d740841f387215b0e903/src/redist/targets/BundledTemplates.targets#L193

and that should include the same nupkg. I looked at the template.json in the package because I thought maybe there were constraints, but at best it seems you can confine templates to a specific OS platform and there are no constraints for the Blazor templates.

Looks like there are no reasons for the template to be missing, yet we have a customer who claims that it does. Do we have someone who can validate this and see if this is indeed the case?

On my M2 mac, the Blazor Web App template is present from the CLI

The description in the original image is from the 7.0 template: https://github.com/dotnet/aspnetcore/tree/release/7.0/src/ProjectTemplates/Web.ProjectTemplates/content/BlazorServerWeb-CSharp. It's since been renamed to BlazorWeb-CSharp (I think) - @mkArtakMSFT @SteveSandersonMS can you confirm? @olafurfannsker were you creating a 7.0 project or an 8.0 project?

[mkArtakMSFT]

The rename to Blazor Web happened only in 8.0

This sounds like a general templating issue in that case, transferring to dotnet/templating repo

Given that the .NET 8 shipped and we haven't heard more concerns about this I think this is not an issue impacting many customers.
That said, we still need to try to understand what's going on here.
