Subject: Re: [WiX-users] Which way to install a Windows service is best?
1. There are several issues that are resolved by using DTF to run managed
code custom actions, among which is a problem whereby if a custom action
instance of msiexec loads the managed runtime and is reused for a different
action, it can't load a different version of the runtime (if needed). By
calling out to an out-of-process and using a pipe to provide all the
advantages of in-process you prevent that problem while also preventing the
issues with out-of-process (aka EXE) CAs. It is the current recommended best
practice.
2. Yes, you should put your CA in the binary table. Using assemblies you
install leads to several of the evils of self-registration. If you use DTF,
you can package multiple assemblies in the same CA "DLL", so you should be
able to design a system whereby you don't have to ever depend on anything
except the .NET framework you built against.
3. See the DTF.chm file in your WiX installation's doc folder.
[CustomAction]
public static ActionResult SampleCustomAction1(Session session)
{
session.Log("Hello from SampleCA1");
session["PROPERTYINEED"] = "My property's value";
if(1 == 1)
{
return ActionResult.Success;
}
else
return ActionResult.Failure;
}
