Re: Exception using EntityFramework 5

EF6 runs great on OS X - in 64 bit mode too - using the System.Data.SQLite data provider.
Our object model is reasonably complex.

My setup is:

Get EF6 from Nuget
Mono 3.2.3 - a bit ancient I know - something more modern would be better
Runtime v4.0.30319

You have to supply metadata specifying the individual EDMX component paths

metadata=./edmxResourcesToEmbed/BrightPay.csdl|./edmxResourcesToEmbed/BrightPay.ssdl|./edmxResourcesToEmbed/BrightPay.msl;provider=System.Data.SQLite
