</PropertyGroup>

</Target>
Error was raised! So, how can I do it? Please help!
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) < 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<
)
