The following public enumerations were added: Description
Aspose.Tasks.UndefinedConstraintHandlingBehavior.None The default behavior for loading from XER format.
Aspose.Tasks.UndefinedConstraintHandlingBehavior.SubstituteWithStartNoEarlierThan Constraints with type ‘ConstraintType.StartNoEarlierThan’ and date = Start are added for tasks with ‘Undefined’ constraint.

Examples and additional notes

In this release we focused on improvement of Primavera XER format support.

Related issue: TASKSNET-4602 - Extend XER import to support XER files with more than 1 projects

The support of reading of XER files containing multiple projects was added. Also PrimaveraReadOptions class was introduced to make a unified API for both Primavera XML and Primavera XER formats reading. PrimaveraReadOptions.ProjectUid can be used to specify ID of project to read. You can use PrimaveraXerReader to read IDs of projects contained in .XER file:

string xerFile = "test.xer";
PrimaveraXerReader reader = new PrimaveraXerReader(xerFile);
var projectUids = reader.GetProjectUids();
var projectId = projectUids[0];

var firstProject = new Project(xerFile,
    new PrimaveraReadOptions()
    {
        ProjectUid = projectId
    });

Related issue: TASKSNET-10500 - Add a way to specify behavior of task constraints import for XER format

PrimaveraReadOptions.UndefinedConstraintHandlingBehavior was added to make it possible to specify behavior used to handle tasks with Undefined contraint when reading project. Prior to 22.4 the default behavior was to add “StartNoEarlier” constraint with “Start” date for these tasks. Now the default behavior is “None” (no constraints are added).

var firstProject = new Project("test.xer",
    new PrimaveraReadOptions()
    {
        ProjectUid = 1,
        UndefinedConstraintHandlingBehavior = UndefinedConstraintHandlingBehavior.SubstituteWithStartNoEarlierThan
    });
