How do I tell Entity Framework to use SQL Server Compact in code first?

Question

How do I change my app.config or Migration Configuration.cs file so Entity Framework uses a local SDF file instead of a local SQL Server instance ? I am using EF 6.1.

Thanks

You should just be able to specify the ProviderName in the connection string to your database.

<connectionStrings>
<add name="DataModelContext"
     providerName="System.Data.SqlServerCe.4.0"
     connectionString="Data Source=location\cfdb.sdf"/>
