Using `quality` and `channel` in A.B format doesn't cause warning despite not being supported

[PhilippNaused]

Using a command like .\dotnet-install.ps1 -Channel 10.0 -Quality daily -DryRun doesn't cause any warning or error.
But the docs clearly say that this is not supported:

install-scripts/src/dotnet-install.ps1

Line 33 in 8aa77d1

For SDK use channel in A.B.Cxx format: using quality together with channel in A.B format is not supported.

install-scripts/src/dotnet-install.sh

Line 1799 in 8aa77d1

echo " For SDK use channel in A.B.Cxx format. Using quality for SDK together with channel in A.B format is not supported."

It appears that when using the --channel and --quality parameters together, the install script selects and downloads the latest SDK version within the specified channel that matches the desired quality:

• ./dotnet-install.sh --channel 8.0 --quality daily --dry-run -> ./dotnet-install.sh --version "8.0.320-servicing.25561.2"
• ./dotnet-install.sh --channel 8.0 --quality preview --dry-run -> ./dotnet-install.sh --version "8.0.100-rc.2.23502.2"
• ./dotnet-install.sh --channel 8.0 --quality GA --dry-run -> ./dotnet-install.sh --version "8.0.416"

In each case, the script determines the highest available version in the specified channel that matches the quality criteria, rather than warning or erroring. This behavior may differ from what the documentation suggests.

Since the behavior appears to work, we should consider updating the documentation.

There is even an example of using it this way:

install-scripts/src/dotnet-install.ps1

Lines 104 to 106 in 8aa77d1

	.EXAMPLE
	dotnet-install.ps1 -Channel 8.0 -Quality GA
	Installs the latest GA (general availability) version of the .NET 8.0 SDK
