After launching Seesmic this morning, it recommended I update to the most recent version – Seesmic Desktop 2, version 1.1.0.1451, released on 1/13/2011. After verifying that I have the correct version of Silverlight, 4.0.51204.0, I let Seesmic update itself. When it was done, it said I would have to restart Seesmic to use the new version, so I exited the application. Then this popped up:
Notice that the exception occurred in coreclr.dll. A very brief online search indicates that this may not be specific to Silverlight; at least one case I saw was in .NET 3.x.
The full problem signature details are:
