EPPlus Format cell as text.

I need to type like 08x-xxx-xxxx but can't because General format will convert text to number and will be 8x-xxx-xxxx that not fit requirement.

fix this by
worksheet.Cells["A1"].Style.NumberFormat.Format="@"

this command will convert cell to Text Style.

This error can happen when u try to publish .NET MVC (asp.net 4.00)

because u use Entity Framework 5 with .NET 4.0 instead of 4.5   

simple to fix this is uninstall Entity Framework 5 and re Install it.

use library package manager to do this

and after that may be u found this because u update plugin with "library package manager"
