I\'m upgrading a big web site project from Visual Studio 2010 to 2012. Throughout my project, I have table
elements with the runat=\"server\"
attribute
Microsoft has confirmed this is a bug. They will create a hot fix for it, and include the fix in the next service pack. It doesn't sound like this is a high priority, so it will probably take a while for the hot fix.
2012-10-01 Update: Microsoft support contacted me and said this will be fixed in an upcoming hot fix "soon".
2012-11-28 Update: Visual Studio 2012 Update 1 does not fix the problem.
