ASP.NET April 2009 Hotfix Rollup Available
Late last month we released a hotfix rollup that includes several fixes. We released these fixes in a rollup because we felt that many customers would be impacted by these issues and we wanted the fixes available to you easily without having to call and open a support incident.
You can read more about the rollup in KB article 969612. Included in the article is a list of all of the fixes contained in the rollup.
