MongoDB has announced the public preview release of its MongoDB Provider for Entity Framework Core (EF Core), enabling C# developers to integrate MongoDB with their applications while utilizing familiar APIs and design patterns. This development addresses the previous lack of first-party support for EF Core, which had led some developers to rely on community-built projects for MongoDB integration. The new provider supports code-first workflows, basic CRUD operations, LINQ queries, change tracking, and class mapping, with plans for future enhancements. Meanwhile, MongoDB's leadership will transition as CEO Dev Ittycheria retires, with Chirantan "CJ" Desai stepping in as the new CEO effective November 10, 2025. CJ brings extensive experience from ServiceNow and Cloudflare, positioning him to guide MongoDB through its next growth phase, dubbed "MongoDB 3.0," which aims to capitalize on the opportunities presented by AI and data-intensive applications. Ittycheria emphasizes the strategic timing of the leadership change and expresses confidence in MongoDB's future, highlighting the company's solid footing and strategic direction.
