<Property Condition="'String A' == 'String B'">
    Property Value
</Property>

Attributes and Elements

The following sections describe attributes, child elements, and parent elements.

Attributes

Attribute	Description

Condition

Optional attribute.

Condition to be evaluated. For more information, see MSBuild Conditions.

Child Elements

Parent Elements

Text Value

A text value is optional.

This text specifies the property value and may contain XML.

Remarks

Property values are referenced in the project by placing the property name between "$(" and ")". For example, $(builddir)\classes would resolve to "build\classes", if the builddir property had the value build. For more information on properties, see MSBuild Properties.

Example

The following code sets the Optimization property to false and the DefaultVersion property to 1.0 if the Version property is empty.

<PropertyGroup>
    <Optimization>false</Optimization>
    <DefaultVersion Condition="'$(Version)' == ''" >1.0</DefaultVersion>
</PropertyGroup>
