Does Microsoft Jet DB work with Entity Framework?

In this forum here , someone mentions that Entity Framework does not work with Access (Jet DB - .mdb). However it seems that there is a provider for Jet DB as described here

Which makes me think that the only thing I need with Entity Framework is to define the follwing before I define the models:

<connectionStrings>  
    <add name="ProductContext"
         providerName="Microsoft.Jet.OLEDB.4.0"
         connectionString="Source=C:\mydatabase.mdb;Jet OLEDB:Database
                           Password=MyDbPassword;"/>
</connectionStrings> 

Does anyone know if Entity Framework works fine with Jet DB, I want to make sure it does before I start since my design document depends on this fact.

Thanks

That is provider for ADO.NET but not for EF (you need one more provider). MS Access is not supported. If you need local database use SQL Server CE or SQL Server Express.Inspectorate

Entity Framework does not support OLEDB connections, so your connection string will not work. It is practically impossible to get Entity Framework to collaborate with MS Access. You will either need to dump the MS Access part of your design, or the Entity Framework part.

The closest you could get using MS Access is using strongly typed datasets and Linq-to-DataSet http://msdn.microsoft.com/en-us/library/bb386977.aspx

Or, considering going with SQL Express instead (it's free) http://www.microsoft.com/sqlserver/en/us/editions/2012-editions/express.aspx

Do you know of any open-source providers written for jet db to work with Entity Framework? ThanksAdjunction
There are none unfortunately. Like I said, you will have to abandon one of the elements of your design, MS Access or EF.Trinitrocresol

There is a MS Access EF 6.1 provider here

EDIT
Now the EF provider for Access is hosted on GitHub
