When I’m reviewing new projects, or being really strict in checking builds I like fully delete anything cached on my local dev machine so it will emulate a fresh build server.
Clearing the Caches
There are 3 ways to clear NuGet caches that I know about
VS2019, Tools, Options, NuGet Package Manager, General, Clear all caches
Or from the command line, and these both seem to do the same thing. NuGet CLI Download
dotnet nuget locals all --clear nuget locals all -clear
Which gives output:
Clearing NuGet HTTP cache: C:\Users\dave\AppData\Local\NuGet\v3-cache Clearing NuGet global packages folder: C:\Users\dave\.nuget\packages\ Clearing NuGet Temp cache: C:\Users\dave\AppData\Local\Temp\NuGetScratch Clearing NuGet plugins cache: C:\Users\dave\AppData\Local\NuGet\plugins-cache Local resources cleared.
Clearing packages folder
Even doing a Clean Solution in Visual Studio won’t get rid of the packages folder in the solution.
So remember to delete
packages in your solution (then watch inside the directory as it rebuilds)
As a side note - the
packages folder should not be checked into source control (it is ignored in the default .NET .gitignore file)
The above was working from a .NET Framework solution using VS2019.
There does seem to be differences in the .NET Core solutions. See here
