Updating a packagesuggest change
To update a package use the following command:
PM> Update-Package EntityFramework
where EntityFramework is the name of the package to be updated. Note that update will run for all projects, and so is different from
Install-Package EntityFramework which would install to “Default project” only.
You can also specify a single project explicitly:
PM> Update-Package EntityFramework -ProjectName MyFirstWebsite
