i installed EntityFramework.SqlMigrations NuGet Package and i get this error . it worked for me in the past and somehow, now it does not work.
PM> update-database The term 'update-database' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again. At line:1 char:16 + update-database <<<< + CategoryInfo : ObjectNotFound: (update-database:String) , CommandNotFoundException + FullyQualifiedErrorId : CommandNotFoundException
Occurs with EF5 RTM, VS2012 RTM.
I experienced this problem today. I executed "Update-Package EntityFramework" in the PM Console. No changes were reported by NuGet and the problem persisted. I then restarted VS2012 and re-attempted Update-Database and it worked as expected. It's not clear what caused this problem, it's also not clear whether the Update-Package contributed to correcting it or not.
First try restarting Visual Studio, then try Update-Package EntityFramework followed by a restart.
I just used this command:
Update-Package EntityFramework -Reinstall
