Missing "No templates found matching:..."-message when using `-minimal` option with `dotnet new`

See original GitHub issue

Describe the bug

When using dotnet new with the -minimal option, no “No templates found matching:…”-message is shown to the user, if no matching template exists. Instead a generic “For more information, run:…”-message is shown.

To Reproduce

The issue can be reproduced by running dotnet new with the -minimal option, and a combination of template and language that doesn’t exist. The example below uses the webapi template with -lang option “F#”, since no minimal webapi-template exists for F#:

$> dotnet new webapi -minimal -o TodoApi -lang F#
For more information, run:
   dotnet new webapi -h

I was expecting to see a “No templates found matching:…”-message, informing me that no F#-version of this template exists, but was instead shown a “For more information…”-message.

Expected behavior

To illustrate the expected behavior, I’m including an example of trying to create a new project without the -minimal option, using the grpc template with -lang option “F#”, another combination for which no template exists:

$> dotnet new grpc -o TodoApi -lang F#
No templates found matching: 'grpc', language='F#'.

To list installed templates, run:
   dotnet new --list
To search for the templates on NuGet.org, run:
   dotnet new grpc --search

As expected, a “No templates found matching:…”-message is printed to the console, and I would expect the behavior of dotnet new to be similar to this when using the -minimal option.

Further technical details

I’m using Ubuntu 20.04.3 LTS (64-bit version), and running the dotnet command straight from the default terminal (gnome-terminal).

The output from dotnet --info is as follows:

Background

Discovered this bug following the Microsoft Tutorial: Create a minimal web API with ASP.NET Core. This tutorial also introduced me to the -minimal option in .NET CLI.
