IVSPackageInstaller/IVsPackageInstaller2 install dependency lowest version

[BilgehanYildiz]

when I want to install with dependencies it is not install latest version of dependency.It is installing lowest version of dependency.

IVsPackageInstaller2.InstallLatestPackage or IVsPackageInstaller
Scenario
Package A Latest Version 1.0.5 and has dependency to Package B
Package B Latest Version 1.0.9 and lowest version is 1.0.0
when I install PackageA it is installed 1.0.5 and find its dependecy package B and install lowest version 1.0.0
How can I force to install dependency latest version too.
Regards

@BilgehanYildiz
NuGet resolves the dependencies to the lowest by design.
I would assume you're using packages.config based projects?
In that scenario currently only the user itself can specify the dependency resolution strategy.

If you're concerned with getting the latest package, I'd suggest installing that explicitly, and passing ignore dependencies as false.

Here's our resolution strategy for PackageReference projects.
There is no way to force highest dependency resolution in the PackageReference case.
Related issue#5553 for a different resolution behavior.

Does this answer your questions/unblock you?

This cause performance issue from me each time I check package dependency find its latest version and install it?What you suggest?

[nkolev92]

If you know the dependency tree, you don't need to specify the version. Then NuGet's caching mechanism would make it a little more performant, but still lower than letting NuGet do it's own thing.

Can you tell us more about your scenario?

Why is it important for you that the transitive dependencies are latest?

Do you own all packages to be installed? Or do you only own the direct dependency?
Having Package X install with different transitive dependencies depending on the time of the installation, increases the test matrix and could lead to more problems.

Is your scenario public?

Please note that historically we haven't been adding IVS NuGet APIs very lbierally, we'd need a good amount of customers to ask for us to consider an enhancement.

Hi I dont know dependency tree.But if nuget has api for that I can find.Actually myrequest is simple I want to use installatestmethod with latest dependency if you add this feature it is functional.I own all packages.A sample scenario I have a OracleDataAccess dependecy with my package and OracleDataAccess dependecy is latest version.When I use installlatest that time it decrease my oracledataaccess version and it cause problem

[nkolev92]

If you own all packages, you already know the dependency tree then.
It's the package you own, and all the packages that the package you own depend on.

Do you really need to be using IVs APIs if you're not shipping an external feature?

I already write my code,but if you add this feature to vsinstaller it is helpful.A parameter like ignoredependcy.something like that DependecyLevel lowest or highest thanks
