MSBuild Best Practices
We recommend the following best practices for writing MSBuild scripts:
Default property values are best handled by using the Condition attribute, and not by declaring a property whose default value can be overridden on the command line. For example, use
<MyProperty Condition="$(MyProperty)" == ''>
MyDefaultValue
</MyProperty>
Avoid wildcards when you select items. Instead, specify files explicitly. This makes it easier to track down errors that may occur when you add or delete files.
