Project Data Reading and Writing
Aspose.Tasks for .NET provides tools to access and modify core project-level properties in Microsoft Project files. These properties include project metadata, scheduling settings, and other global attributes. The API supports both reading and writing operations for XML and MPP formats, with compatibility across multiple Microsoft Project versions. The table below outlines which properties are available for each format and version, helping developers understand what data can be handled programmatically.
