Describe the bug

Trying to add a new apphost to a new solution, but running into an error:

➜  Notifications git:(main) dotnet new aspire-apphost -o TSWCloud.NotificationService.AppHost
No templates or subcommands found matching: 'aspire-apphost'.

To list installed templates similar to 'aspire-apphost', run:
   dotnet new list aspire-apphost
To search for the templates on NuGet.org, run:

This is one Fedora Workspace 41.

Upgraded to .net 9 via the shell script here: https://learn.microsoft.com/en-us/dotnet/core/install/linux-scripted-manual Using the command ./dotnet-install.sh --channel 9.0 I've installed it this way because I'm having trouble getting the latest version via the Fedora package manager. (A bit of that saga is described here: https://github.com/dotnet/aspire/issues/5205)

Expected Behavior

It creates an apphost project for me.

Steps To Reproduce

Run the command dotnet new aspire-apphost -o TSWCloud.NotificationService.AppHost

Exceptions (if any)

Did you install the aspire templates?

https://learn.microsoft.com/en-us/dotnet/aspire/fundamentals/aspire-sdk-templates?pivots=dotnet-cli

@davidfowl Wow, I was being really dumb.

Didn't think that updating to dotnet 9 would require having to add the templates.

Makes sense in retrospective.

➜  dotnet new install Aspire.ProjectTemplates
The following template packages will be installed:
   Aspire.ProjectTemplates

Installing the template package(s) will override the available template package(s).
The following template package(s) are already available:
   Aspire.ProjectTemplates::8.2.2

To install the template package(s) anyway, apply '--force' option:
   dotnet new install Aspire.ProjectTemplates --force

The aspire templates are not part of the .NET sdk as yet

dotnet / aspire
