How do I gracefully update boost which have been got via NuGet in Visual Studio?

Question

I get boost library from Manage NuGet Packages in Visual Studio 2019.

There are several versions in the packages folder. I have deleted several, left the latest. However, when I rebuild a project, the old one boost.1.71.0.0 would come up again.

I tried to modify MyProject\packages.config and MyProject\MyProject.vcxproj files. Replaced all boost.1.71 with boost.1.77,

It still doesn't work. boost.1.71.0.0 persist coming up.

You could also try this method.The problem is caused by the cache, you need to clear the cache. Before that, you need to make a backup of the folder where the nuget package is stored in the project folder and delete it (if it exists). I suggest you try Tools> NuGet Package Manager> Package Manager Settings> click Clear All NuGet Cache(s), then restore packages (right click solution node> Restore NuGet Packages). And I suggest you read this document carefully and run dotnet nuget locals all --clear or nuget locals all -clear to clear the nuget cache completely.

Answer 2

@zvikan's comment is correct, I succesfully updated my boost version.

Removed package 'boost.1.71.0' from 'packages.config'
Successfully uninstalled 'boost.1.71.0' from MFCTest
Removed package 'boost_date_time-vc142.1.71.0' from 'packages.config'
Successfully uninstalled 'boost_date_time-vc142.1.71.0' from MFCTest

boost.1.71 disappeared automatically in the packages folder.
