Update to .Net Framework – appears to make your system very busy for a while…
Rob Eisenberg blogged on the 11th that the updates appeared to break WPF (make it very slow). Engaging with him, our team figured out it wasn’t the Office patches that he thought it was, but it was an issue with the re-NGENing of assemblies after 1 or more patches to the .Net Framework.
This morning, I saw an email from a colleage that the issue had been slashdotted and mentioned on The Register. It appears that this is impacting many systems…where they are busy doing a bunch of work, by a service that is just trying to get assemblies NGENed appropriately.
I figured blogging about what we know, early, will help people deal with with it…information will minimize the impact.
MS07-040 – addresses a vulnerability in the .NET Framework was one of the 7/10/07 updates.
Some Quick background.
- .Net 1.0, 1.1. and 2.0 were patched.
- .Net 3.0 systems require .Net 2.0
If you have .Net 1.0, 1.1 and 2.0 on a system, I believe all the patches will be installed.
We’re sorry for any impact, and want to work with people to minimize it. Personally, it didn’t adversely affect any of my work machines or my machines at home. Perhaps because updates were done before I was trying to use the machine.
More soon under the category "Ngen Patch"…
