Re: [WiX-users] how to enforce assembly to be gac'd even when thereisalready a copy in the gac

I'm beginning to sound like an echo in here....
 
What's wrong with http://windowssdk.msdn.microsoft.com/en-us/library/aa372360.aspx  and using FileVersion to force an in-place update of your assembly into the GAC.
 
If it's good enough for InstallShield ;=) .....

I think what I should do is to have a launch condition that if it sees the same assembly already in GAC, the setup should not proceed.  It is because even if setup succeeded, it would not install the DLL in setup but kept the current DLL in GAC.  However I have dug around and don’t know how to do the launch condition…..  <FileSearch> element does not seem to have a way to search in GAC.

 

If I could implement the launch condition, the option of not failing during uninstall isn’t necessary to me.

 

Thanks,

Frank

The current behavior is that when the dll was not put in GAC due to the same version already in GAC, the ngen action didn’t happen.  I have tried adding a custom action that calls ngen.exe as below.


Please don't do it that way. As written, you don't handle rollback or uninstall. Folks from the Visual Studio and WiX teams spent a lot of time to get that behavior right. You can't change how .NET treats assemblies with the same strong name but having the option to not fail on an uninstall is a reasonable feature request. Please file it and we can take a look at adding it.
