Description

Creating new MAUI Blazor Sample App from CLI is .NET 9 by default

Steps to Reproduce

1. Install the .NET 10 GA from here
2. Install MAUI workload from the rollback file along with the necessary feeds: rollback.json
3. Create an empty folder and open it on terminal/CMD
4. Run the command dotnet new maui-blazor --Empty
5. Go back to the folder and open the csproj on VS/VS Code
6. Observe that the default .NET SDK is .NET 9 instead of .NET 10

Actual Behavior:
The default .NET SDK version on the created MAUI Blazor Sample app from CLI is .NET 9

Expected Behavior:
The default .NET SDK version should match the SDK and MAUI version, in this case, .NET 10.

@Marnie-Majait what happens if you don't use --Empty? Can you give the output of dotnet new maui-blazor --help?

[Marnie-Majait]

Hi, @mattleibow! If I don't use the --Empty command, it would create a MAUI Blazor app with the sample content. This is the output if you type in --help:

I've tried to do the --empty command and it also created a MAUI Blazor app without sample content, and it created a .NET 10 project.

ok, so uppercase is net9 and lowercase is net10?
