Impact

It bothers me. A fix would be nice

Repro Steps & Context

Repro steps:

1. Set the environment Variable NUGET_TRANSITIVE_DEPENDENCIES_IN_PMUI=1.
2. Create a new C# Console App (.Net Core) project.
3. Right-click the project in Solution Explorer and select ‘Manage NuGet Packages…’ menu item to open PM UI.
4. Click “Browse” tab, search a package (e.g. “Microsoft.EntityFrameworkCore”) that has dependencies, select a package version [6.0.4] in the "Version" drop-down list in the right panel and click the “Install” button on the right.
5. Switch to “Installed” tab.

Expected:

The transitive package should show in “Installed” tab.

Actual:

The transitive package doesn’t show in “Installed” tab as below screenshot.

Notes:

1. The transitive package can be show in “Installed” tab after closing solution/VS and reopening the same solution.
2. The issue starts from NuGet Client Dev\6.4.0.90.

@v-longmin do you get the desired behavior if you choose File -> Save All after the Install completes, but before opening the Installed tab?

@jebriede may be able to speak to the caching strategy used for this feature. I would guess that what's happening is the assets file isn't being re-generated, and the UI is reading/showing stale data from the previous restore.

I can repro the bug on latest VS with NuGet 6.4.0.90; investigating.

When a package is installed, this should invalidate inner cache in PackageReferenceProject and, then, repopulate them.

There seems to be a race condition when we re-read the assets file and when the assets file is restored with updated info.

@dominoFire It doesn't work after choosing file -> save all after the install completes.
