AddNewProperty(String, String)

This method (and the whole namespace) is deprecated. Please use the classes in these namespaces instead: Microsoft.Build.Construction Microsoft.Build.Evaluation Microsoft.Build.Execution

The AddNewProperty method adds a new property element to the persisted <PropertyGroup> at the end. This method takes the property name and value as strings directly, so that the BuildProperty object can be created with the correct owner XML document and parent XML element.

AddNewProperty(String, String, Boolean)

This method (and the whole namespace) is deprecated. Please use the classes in these namespaces instead: Microsoft.Build.Construction Microsoft.Build.Evaluation Microsoft.Build.Execution

Adds a new property to the PropertyGroup, optionally escaping the property value so that it will be treated as a literal.

Remarks

The following example creates a Project object and uses the LoadXml method to add content to the project. The BuildProperty, BuildPropertyGroup, and BuildPropertyGroupCollection classes are used to add, remove, and change items in the project.
