[Bug Bash] The second project doesn't generate “packages.lock.json” file after restoring project with command under solution path with enabling ‘RestorePackagesWithLockFile’

[CiciLi1]

NuGet Product Used

Visual Studio Package Management UI

Product Version

NuGet Client Dev\6.13.0.79

Worked before?

It is not a regression since it also reproes on D16.11\34601.136 with implicit NuGet Client 5.11.6.4 and D17.12\33527.113 with implicit NuGet Client 6.12.2.1.

Impact

It bothers me. A fix would be nice

Repro Steps & Context

Notes:  

1. The repro rate is 100%. 

2. This issue does not repro when you save the project in step 5 by clicking the “Save” button on the top of VS.

Repro Steps:   

1. Create two “C# Class Library (.NET Framework 4.8.1)” projects.   

2. Right-click the solution in Solution Explorer window and select "Manage NuGet Packages for Solutions…" menu item to open solution-level PM UI.   

3. Click “Browse” tab and select “nuget.org” from “Package source” drop-down list.

4. Install a package (e.g.Newtonsoft.Json) with “PackageReference” format into both projects.

5. Right-click the project in Solution Explorer and select “Unload project”, click the “Save” button in prompt dialog box. (Both projects operate in the same way.)

6. Set MSBuild property “RestorePackagesWithLockFile” to true in csproj file for every project.

<RestorePackagesWithLockFile>true</RestorePackagesWithLockFile>

6. Reload projects and click “Tools -> Command Line -> Developer Command Prompt”

7. Run restore command “msbuild /t:restore /v:d”.

Expected:   

It should have generated ‘packages.lock.json’ file alongside *.csproj file in every project.

Actual:   

The second project doesn’t generate “packages.lock.json” file as below screenshot:

Hi @CiciLi1 , thank you for clarifying.

I clicked on the save button from the prompt only. However I was not able to reproduce the issue. As soon as I clicked save in the pop up window the lock file was generated
