Use RequiredVersion 1.9.2 but download dependencies with v2.1.0

[yuanweilei]

I run this command on my local PowerShell to save v1.9.2, but some dependencies with v2.1.0 is downloaded. Could you please tell me why?
Save-Module -Name Microsoft.Graph -RequiredVersion 1.9.2 -Path .\modules

For example, Microsoft.Graph.Applications.

The ability to install older versions of the SDK was added in v1.12.2. All versions prior to v1.12.2 didn't support an exact version match for their dependencies. See v1.12.2 release notes for more details - https://github.com/microsoftgraph/msgraph-sdk-powershell/releases/1.12.2.

Please use the latest version of v1.x (v1.28.0) if your goal is to use v1.x - Install-Module -Name Microsoft.Graph -RequiredVersion 1.28.0.

Thank you very much! I will try to use 1.12.2.

Could I ask you another question? I asked this question here
About 10 days ago (before v2.0.0 release), I used the same command but Microsoft.Graph.Applications v1.9.6 was downloaded. You told me that v1.28.0 is the latest version of v1.x, but why v1.9.6 was downloaded?

Save-Module -Name Microsoft.Graph -RequiredVersion 1.9.2 -Path .\modules

I'd recommend you use v1.28.0 as it is the latest stable release of the v1.x SDK.

As for:

About 10 days ago (before v2.0.0 release), I used the same command but Microsoft.Graph.Applications v1.9.6 was downloaded. You told me that v1.28.0 is the latest version of v1.x, but why v1.9.6 was downloaded?

Save-Module -Name Microsoft.Graph -RequiredVersion 1.9.2 -Path .\modules

This is more of a question for the author of the Save-Module command. My theory is:
Save-Module installs any version of Microsoft.Graph.Authentication greater than or equal to 1.9.2 since 1.9.2 is specified as the minimum version. This is because in all versions prior to v1.12.2, the dependency version of Microsoft.Graph.Authentication was specified under ModuleVersion (>=). This was later changed to RequiredVersion (=) in v1.12.2+ to support installation of older versions. See https://learn.microsoft.com/powershell/module/microsoft.powershell.core/about/about_module_manifests?view=powershell-7.3#requiredmodules for more details:

ModuleVersion - Specifies a minimum acceptable version of the module.
RequiredVersion - Specifies an exact, required version of the module.

Thank you again. Understood the question above is regarding Save-Module.

I am still confused why Microsoft.Graph -RequiredVersion 1.9.2 got v1.9.6 not the latest v1.28.0, but maybe I should ask this question on PowerShell side.

I just guess, maybe v1.9.6 is the last version of v1.9.z, so it is download. (There are versions of v1.10.0, 1.11.0, ..., v1.28.0 >= v1.9.2)

Awesome! The author of Save-Module is the right contact point for the question.

I'll close the issue since the original question has been answered by #2164 (comment). Feel free to open a new issue if the problem persists.
