I have a Winform App that uses a 3rd Party Library of Controls, DevExpress. I also created a bunch of Controls myself, extending those controls. Everything has been working fine when all of a sudden I opened VS today and on the Design Page all my extended controls were missing. I then tried rebuilding to no avail. Then I tried Cleaning and Rebuilding and made it even worse. Now I have tons(520) of erros stating things like -->

Error 179 The name 'datBirthDate' does not exist in the current context D:\Documents\Visual Studio 2008\Projects\MatrixReloaded\MatrixReloaded\Controls\Member\ucGeneral.cs 339 17 MatrixReloaded

also if I try to open a form or user control in Design Mode I first get this -->

could not find type, "MyType" please make sure that the assembly that contains this type is referenced

and then, if I click Ignore and Continue I get this for all Forms and Contros when I try and look at them in Design Mode --> Exception of type System.OutOfMemoryException was thrown

Help!?!?

When I googled I came across mostly references to VS 2003...I am on 2008 sp1.
