Olá pessoal, quando baixei o projeto da CAELUM, descompactei e abri ele no Visual Studio, apareceu a seguinte mensagem:
"The Web project 'CaelumEstoque' requires SQL Server 2012 Express LocalDB, whick is not installed on this computer.
To upgrade the project database to use latest SQL Server Express LocalDB, double-click the database file and follow the instructions. Note: After this upgrade, the project database can't be modified using earlier verions of Visual Studio."
O que faço? Obs.: Estou usando Visual Studio Community 2015.
