My product has several features including two services. Let's call them ServiceA and ServiceB. Both of these service features are optional. However if both ServiceA and ServiceB is selected during install I want to create a service dependency between them so that ServiceB will depend on ServiceA (in other words ServiceB must always start before ServiceA is launched).
How do I achieve this in WIX 3.6?

<ServiceInstall Id="ServiceA" DisplayName="ServiceA" Name="ServiceA"
Account="LocalSystem" Start="auto" ErrorControl="normal" Type="ownProcess">
<ServiceDependency Id="ServiceB"/>
</ServiceInstall>
That should work, check out ServiceDependency documentation element
