The latest releases 0.57 and higher no longer require a connection string name to be passed to the EFContextProvider.  As per the suggestion, the connection information is now retrieved from the ObjectContext or DbContext directly.

We will try to make this more configurable before the next release.

I noticed that for Metadata is required a ConnectionStrings from which breeze finds the .cdsl (I examined the source.) while for the effective database use I was able to pass a runtime context like this : (i am using DB first and objectcontext)
Public Class myController
    Inherits ApiController
    Implements IReadOnlySessionState

    Private contextProvider As Breeze.WebApi.EFContextProvider(Of mydb.myEntities)

    <AcceptVerbs("GET")> _
    Public Function Metadata() As String
        Return contextProvider.Metadata  ' not working at run time without connectionstring
    End Function

    <AcceptVerbs("GET")> _
    Public Function GetConfig() As IQueryable(Of mydb.MY_CONFIG)
        Return contextProvider.Context.MY_CONFIG  ' working at run time
    End Function

I hope that in a next release they will be able to implement for the metadata the possibility to retrieve the .cdsl from the connection string of the run time context instead of using the costant in web.config.
Otherwise is not difficul to modify the source code.

I'm using a repository pattern with EF and I'd like to try out using Breeze. How can I create an EFContextProvider without passing it a connection string? Is there a way to use an already opened dbcontext?

Thanks,
Rick
