Serializable classes and dynamic proxies in EF - how?

Question

In [a previous posting], I was set on the path to having to clone my entities. This I\'ve attempted to do with a serialisation approach as found in [codeproject].

I had the same issue using Entity Framework 6 ( EF6 ). I fixed the issue by changing the T4 template and adding the line [Serializable] between the Using Directives and the Entity Class Opening line. Like so:

 <#=codeStringGenerator.UsingDirectives(inHeader: false)#>
 [Serializable]
 <#=codeStringGenerator.EntityClassOpening(entity)#>

No other changes required.
