Custom VS extension development

[13thirteen]

Visual Studio Version:
VS Community 2019 16.6.5

Summary:
In my custom VS extension SwitchStartupProject (on the Marketplace) I use ILaunchSettingsProvider to programmatically change debug settings of multiple startup projects.
So far I referenced nuget package Microsoft.VisualStudio.ProjectSystem.Managed 2.0.6142705 on nuget.org.

Recently, I found a slightly newer version 2.3.6152103 on your team feed which includes IActiveDebugFrameworkServices that allows my extension to also set the target framework of multi-targeting projects.

Now, I saw there is IPersistOption which might allow my extension to change debug settings without affecting the launchSettings.json files. (I didn't study it in detail yet.) Unfortunately, I didn't find any non-beta and non-rc releases of Microsoft.VisualStudio.ProjectSystem.Managed that include IPersistOption.
The beta releases are not that useful because they have a dependency on package RoslynTools.SignTool which seems not to be public (for obvious reasons) and therefore installation fails.

Questions:

1. Are there somewhere newer non-beta releases of the nuget packages for use by custom VS extensions?

2. As I understand it, these nuget packages are deployed with VS. (e.g. at C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\Common7\IDE\Extensions\Microsoft\ManagedProjectSystem\Microsoft.VisualStudio.ProjectSystem.Managed.dll in my case.) Should my custom VS extension use that VS-bundled DLL somehow instead of the pretty old nuget package? How would I do that?

3. Given the circumstances above, my current approach feels like a hack. Am I even supposed to use Microsoft.VisualStudio.ProjectSystem.Managed from a custom VS extension? Is there another/better way to programmatically set debug settings of CPS projects?

Hi,

My team and I are relying on this great extension from @13thirteen to handle our various launch scenarios (Project1 + Project2, Project1 + Project 3, Project1 + Project2 + Project3,..). It adds a really useful overlay upon the launch profiles feature of VS2019.

However, some caveats still persist, like the fact that the actual version of the nuget package Microsoft.VisualStudio.ProjectSystem.Managed 2.0.6142705 does not allow to change project properties without affecting the local filesystem launchsettings.jsons (we leave a lot of comments in these files, to be able to switch from env variables to other and such, and updating the settings through the SDK erases these comments).
I would like to +1 (a lot :)) to this request, and ask if the latest developed version of the package will ever make it to the public Nuget feed ?

Thank you.

@13thirteen do you know the location of the feed? The myget link is broken. I also need the IActiveDebugFrameworkServices to read the current framework that is selected

ok, I found the pre-release feed in a nuget.config

The pre-release versions of the packages are in the vs-impl feed.
