A new bug today

After installing the latest wsus-updates I could not edit Maintenance Plans on my workstation any longer.

The software was not responding and I found out that the history of the reports in SSMS was gone. It seems to be a problem with a .Net4 update. Uninstalling KB2840628 and rebooting my machine fixed it.

There is a connect item (new SqlConnection("context connection=true") will throw TypeInitializationException->System.Security.SecurityException) for it, other people are facing connection problems after this update as well.

So if you run into this problem, please vote for it and try the workaround in the meantime.

    Updated 7/29/2013 - Hotfix available
    From MS:
    We have confirmed a few different issues with the latest .NET Framework 4 security update, KB 2840628, when applied to SQL Server 2012 (all versions) servers in a Configuration Manager environment.

    A standalone hotfix, KB 2872041, is now available to correct this issue. The new hotfix should be applied to any SQL Server 2012 installation with KB 2840628 that houses a Configuration Manager role, such as a site database or database replica.

    KB2872041: NET Framework 4 applications that rely on a partial trust host may encounter errors

    Application of this hotfix should resolve all of the issues noted in this blog post.
