You can easily use property values for evaluating conditions. Here is an example:

<PropertyGroup>
    <aa>1</aa>
</PropertyGroup>

<Target Name="Build">
    <Message Text="Some text" Condition=" $(aa) &lt; 2 " />
</Target>

Note that:

  • Property values are strings, you must evaluate the condition in the Condition attribute. See MSDN Docs on evaluating conditions.
  • You must escape XML characters (replace < with &lt; )
