[wix-users] IGNOREDEPENDENCIES property?

[Carter Young]

Simple Component Rules enforce MSI behavior and are used for checking.
Continuing with my example:

Component Rule in Game Whizzbang checks that .NET 4.5.2 is installed. 
It was installed via the Component Rule in Software Suite A.  The MSI
tables are only built on a per MSI basis.  There is no way that Software
Suite A knows that Game Whizzbang requires .NET(2 Different MSI's have 2
Different Scopes, that isn't Global).  That's what IGNOREDEPENDENCIES is
for.  The only person who knows they are both installed is you, and your
Programs and Features.

If Suite A requires version 4.5.2 and it isn't installed your installer should install it as a dependency.  In the meantime, I downloaded Game Whizzbang that also requires 4.5.2.  If I unistall Suite A and include the dependency in the Uninstall, I'll unintentionally break Game Whizzbang
