.NET Framework 1.1 hotfixes are not yet offered via Windows Update on Vista

I have heard from a couple of customers who noticed this issue, and I also experienced it on one of my systems yesterday, so I wanted to post an item to give anyone else reading my blog a heads up as well.  If you are running Windows Vista and install the .NET Framework 1.1, you will not currently see hotfixes or service packs for the .NET Framework 1.1 offered to your system if you visit Windows Update.

I asked around and this is a known issue related to the Windows Update package authoring for .NET Framework 1.1 hotfixes and service packs.  Hopefully, we will be able to refresh the authoring for .NET Framework 1.1 items soon, but in the meantime, if you have the .NET Framework 1.1 installed on Windows Vista, please make sure to manually install service pack 1 and post-SP1 hotfixes.

Here are a couple of links to make this easier for you:
