By default NuGet skips updating a package when there is no higher version number. This brought us into trouble because we changed a package without updating the version number(only the file version had changed). So all our developers had to remove and re-install the package.
Until NuGet 2.1 there was no way to force an update regardless. NuGet 2.1 addresses this with the ‘reinstall’ flag.
Let’s have a look at the sample from the NuGet 2.1 release notes:
Previous versions of NuGet would result in the following when attempting to update a package that did not have a more recent package version:
PM> Update-Package Moq
No updates available for 'Moq' in project 'MySolution.MyConsole'.
With the reinstall flag, the package will be updated regardless of whether there is a newer version.
PM> Update-Package Moq -Reinstall
Successfully removed 'Moq 4.0.10827' from MySolution.MyConsole.
Successfully uninstalled 'Moq 4.0.10827'.
Successfully installed 'Moq 4.0.10827'.
Successfully added 'Moq 4.0.10827' to MySolution.MyConsole.
