Creating Task Baseline
Overview
A baseline in project management is a fixed reference point that captures the original planned schedule, cost, and work. By saving a baseline, project managers can later compare it with the actual progress to evaluate project performance and detect variances. Using Aspose.Tasks for .NET, developers can programmatically create task-level baselines or project-level baselines in MPP/XML files without Microsoft Project installed.
When to Create a Task Baseline
Typical scenarios include:
- At the start of a project — to capture the original plan.
- Before a major milestone — to evaluate progress at key checkpoints.
- After re-planning or re-estimation — to track updated expectations.
Working with Baselines in Aspose.Tasks
- The TaskBaseline class represents baseline information for a single task.
- The Project.SetBaseline method allows creating baselines for the entire project or a selection of tasks.
- Each task can contain multiple baselines (Baseline0 … Baseline10 in Microsoft Project).
Creating a Task Baseline
A task baseline can be created using the default constructor for the TaskBaseLine class as shown below.
1Project project = new Project();

3// Creating TaskBaseline:
4Task task = project.RootTask.Children.Add("Task");
5
6// Set baseline for specified tasks and entire project
7project.SetBaseline(BaselineType.Baseline, new Task[] { task });
8project.SetBaseline(BaselineType.Baseline);Best Practices
- Do not overwrite baselines frequently — otherwise variance analysis becomes meaningless.
- Use consistent baseline levels (Baseline0 for initial plan, higher baselines for re-planning).
- Automate baseline creation in code before distributing new schedules to stakeholders.
Conclusion
Creating baselines is a fundamental step in project management that ensures reliable performance tracking. With Aspose.Tasks for .NET, you can easily set baselines for tasks or entire projects programmatically, automate scheduling processes, and integrate this functionality into enterprise project management solutions.
