Couchbase's new EF Core provider enables advanced .NET integrations typically associated with relational databases, including ASP.NET Core Identity, GraphQL, and OData, although these implementations are based on limited testing and are not officially supported yet. The integration with ASP.NET Core Identity requires pre-creating specific collections such as AspNetUsers and AspNetRoles, while GraphQL integration through Hot Chocolate translates queries to Couchbase SQL++ using LINQ capabilities. OData exposure is facilitated by Microsoft.AspNetCore.OData, allowing EF Core data to be accessed as OData endpoints, thus making it easier to connect Couchbase with tools like Excel and Power BI. These integrations, supported by EF Core, allow developers to leverage Couchbase for building secure web applications, GraphQL APIs, and integrating with business intelligence tools, expanding the potential use cases for Couchbase in .NET environments.
