The document discusses basic MSBuild elements including the <Project>, <Target>, <PropertyGroup>, and <ItemGroup> elements. It also discusses common MSBuild tasks like Copy, Delete, and Message. It provides examples of using the Copy and Delete tasks to copy and delete files, and the Message task to display files. It explains the target build order and attributes that control order like InitialTargets, DefaultTargets, DependsOnTargets, BeforeTargets, and AfterTargets.

9. Target Build Order

InitialTargets


DefaultTargets


This Project atttribute specifies which targets are run if a target is not specified
explicitly on the command line.
DependsOnTargets


This Project attribute specifies the targets that will run first, even if targets are
specified on the command line or in the DefaultTargets attribute.
This Target attribute specifies targets that must run before this target can run.
BeforeTargets and AfterTargets

These Target attributes specify that this target should run before or after the
specified targets.

21. Determining the Target Build Order

InitialTargets targets are run.

Targets specified on the command line by the /target switch are run. If you specify no targets
on the command line, then the DefaultTargets targets are run. If neither is present, then the
first target encountered is run.

The Condition attribute of the target is evaluated. If the Condition attribute is present and
evaluates to false, the target isn't executed and has no further effect on the build.

Before a target is executed, its DependsOnTargets targets are run.

Before a target is executed, any target that lists it in a BeforeTargets attribute is run.

Before a target is executed, its Inputs attribute and Outputs attribute are compared. If
MSBuild determines that any output files are out of date with respect to the corresponding
input file or files, then MSBuild executes the target. Otherwise, MSBuild skips the target.

After a target is executed or skipped, any target that lists it in an AfterTargets attribute is
run.
