What is new in this release?

We are happy to announce the release of revamped version of Aspose.Tasks for .NET 8.2.0 . This month?s release enhances the feature of formula calculation in project documents by implementing function and other calculations. Our last month?s release introduced the feature of Reading and Writing formulas from extended attributes of a project. This was our first effort to provide support for formulae calculation using the API. This month?s release further enhances the feature of formula calculations by providing support for Using Tasks and Resource Fields in Formulae. This month?s release now includes support for using a Task and Resource?s fields in formula calculations. For example, a formula can be set to the display the different of task?s finish and deadline dates. This month?s release provides support for usage of arithmetic expressions, for example ((1+3*(2+-5) + 8/2)^3) in formulae. This allows to set any mathematical expression as formula in the extended attribute definition and get as well as save its calculated value in document. Formula value can not only be set to tasks and resource fields, arithmetic expression, and task number fields, but also to Boolean values from the project. This sets the formula to various project/tasks?s Boolean parameters that are then calculated at run-time. This month?s release also introduces a new feature of evaluating various functions defined as formula expression in Extended Attributes. These include Calculation of Mathematical Functions, Calculation of Mathematical Functions, Calculation of Text Functions and Calculation of Date/Time Functions. This month?s release also introduces a new feature of rendering Details column in the MPP to the output using the project view?s DisplayDetailsHeaderColumn property. This includes the list of supported fields such as Work, Actual Work, Actual Overwork time, Baseline Work and Baseline 1-10 Work. This month?s release also includes a number of bug fixes that further improves the overall API functionality. These include issues with Timephasedata from MPP file, Exceptions raised while reading and saving certain MPP files, Issues with Task?s GUIDs in MPP 2013 formats, Wrong start and finish dates while creating manual tasks and many more. Bellows is the list of new and enhanced features included in this new release.

Overview: Aspose.Tasks for .NET

Aspose.Tasks is a non-graphical .NET Project management component that enables .NET applications to read, write and manage Project documents without utilizing Microsoft Project. With Aspose.Tasks you can read and change tasks, recurring tasks, resources, resource assignments, relations and calendars. Aspose.Tasks is a very mature product that offers stability and flexibility. As with all of the Aspose file management components, Aspose.Tasks works well with both WinForm and WebForm applications.
