Classic SharePoint Development
Classic SharePoint Development refers to the traditional approach for building custom solutions on Microsoft SharePoint platforms (primarily SharePoint 2013, 2016, and earlier on-premises versions) using server-side technologies like .NET Framework, SharePoint Object Model, and farm solutions. It involves creating web parts, workflows, event receivers, and custom pages that run directly on the SharePoint server, often requiring full-trust code deployment and deep integration with the SharePoint infrastructure. This model contrasts with modern SharePoint development, which emphasizes client-side technologies and cloud-based approaches.
Developers should learn Classic SharePoint Development when maintaining or extending legacy SharePoint on-premises environments, particularly for organizations with complex customizations that cannot be easily migrated to modern SharePoint Online. It is essential for scenarios requiring deep server-side integration, such as building custom business workflows, complex data processing, or solutions that need direct access to SharePoint's server APIs and databases. Knowledge of this approach is also valuable for understanding the evolution of SharePoint and for handling migration projects from older systems.
