  • 0

I am looking for some advice on how to reduce my Entity Framework library’s dependency on app or web.config files. My app containins an ADO.NET Entity Data Model.

I currently reference this library in a web project, but in order to do so, I must add the connection string to the web app’s web.config before deploying.

I now have a requirement to use the standalone DLL and am unable to alter the parent project’s configuration files to include that of my EF library.

What would be the best way to store my connection string, yet maintain the integrity of my edmx and where should I reference it?

    EntityConnectionStringBuilder builder = New EntityConnectionStringBuilder();
builder.Metadata =
    "res://*/Entities.VDMFinance.csdl|res://*/Entities.YourEntities.ssdl|res://*/Entities.YourEntities.msl";
builder.Provider = "System.Data.SqlClient";
builder.ProviderConnectionString = yourConnectionString;
Dim dc As New YourEntities(builder.ConnectionString)
dc.CommandTimeout = 0;

    You can initialize all your data contexts from static factory that does this all the time. You can get the metadata and provider from the initial connection string that gets generated when you create the entities.
