When I use connection string builder in an ASP.Net 5 application I get this error:
Error CS0012 The type 'DbConnectionStringBuilder' is defined in an assembly that is not referenced. You must add a reference to assembly 'System.Data, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'.
I'm using dnx451 as the framework, any sugestions?
