How to manage files with same name in Wix?

问题

I have some dll compiled either in .Net3.5 or in .Net4.0. (They have the same name)
In wix, I have 2 conditionals features.
Feature A installs .net3.5 dll of my app with ComponentRef Id="Cmp35"
Feature B installs .net4.0 dll with ComponentRef Id="Cmp40"
Features are mutually exclusives, only one feature is installed.

my components:

<?xml version="1.0" encoding="UTF-8"?>  
<Wix xmlns="http://schemas.microsoft.com/wix/2006/wi">  
    <Fragment>  
        <DirectoryRef Id="INSTALLDIR">  
            <Component Id="Cmp35" Guid="..">  
                <File Id="Behaviors.Assembly" Name="$(var.Behaviors.v3.5.gen.TargetFileName)" Source="$(var.Behaviors.v3.5.gen.TargetPath)" />  
               <File Id="Other.Assembly" Name="$(var.Other.v3.5.gen.TargetFileName)" Source="$(var.Other.v3.5.gen.TargetPath)" />  
           </Component>  
           <Component Id="Cmp40" Guid="...">  
               <File Id="Behaviors.Assembly.4.0" Name="$(var.Behaviors.v4.0.gen.TargetFileName)" Source="$(var.Behaviors.v4.0.gen.TargetPath)" />  
               <File Id="Other.Assembly.4.0" Name="$(var.Other.v4.0.gen.TargetFileName)" Source="$(var.Other.v4.0.gen.TargetPath)" />  
           </Component>  
       </DirectoryRef>  
    </Fragment>  
</Wix>

I have an error during the compilation: error LGHT0204: ICE30: The target file ... is installed in ... by two different components on an LFN system:
It seems I have an issue because the filenames are the same...
Is there a way to manage this? thanks!

回答1:

Those are just warnings from ICE30. If you verified that the Components are truly mutually exclusive then you can ignore the warnings because you did what they told you to. :)

回答2:

I typically get around ICE30 warnings by installing the files to different subdirectories and then using a CopyFile element (DuplicateFile table) to clone the file to the desired directory. This works well when your features or components are mutually exclusive and you want ICE to be quiet.
