Подключить обещанную базу данных к ASP.NET

Подключите SharePoint:

Using Azure Hybrid Connection ,BCS with Azure Web App hosting WCF endpoint, we can now expose on-premises SQL data to SharePoint Online and Cloud by external content types (ECTs) or SharePoint Hosted Apps.

Ниже приведены подходы two, с помощью которых BCS может подключать эти источники данных к SharePoint:

1. Azure Web App hosting WCF Service and External Lists
2. Azure Web App hosting WCF Data Service and Hosted Apps

Плюсы:

The advantage of using this approach is the reusability of External Content Types (ECT). ECTs can be used across multiple lists and sites in the same site collection. ECTs can also be used for complex associations across multiple types of data.

public static void InitializeService(DataServiceConfiguration config)
{
// TODO: set rules to indicate which entity sets and service operations are visible, updatable, etc.
config.SetEntitySetAccessRule("*", EntitySetRights.AllRead);

config.DataServiceBehavior.MaxProtocolVersion = DataServiceProtocolVersion.V3;

config.UseVerboseErrors = true;
}
