Language="C#" required in code in front

[fred]

Does anyone know why Language="C#" is required in the code in front of
aspx and ascx files?

for example in the header of my aspx file:

<%@ Control Language="c#" Inherits="Blah.Apps.Controls.Announcement"
CodeFile="Announcement.ascx.cs" %>

if i don't have that in the header, Announcement.ascx.cs in the IDE (VS
2005) will blow up with object does not exist in current context on any
c# code dealing like namespace declarations.

in vs2005 i have tools>options>text editior>file extension set for the
extension .cs - Microsoft Visual C# so shouldn't the aspx.cs and
ascx.cs know to use language C# without explicitly setting it in the
code in front header?

Any info on this is appreciated. Thanks.

oops MT i meant "for example in the header of my ascx file:" instead of
"for example in the header of my aspx file:"

The language=C# bit is referring to any embedded code it may come accross
within the aspx/ascx .. the aspx/ascx is dynamically compiled (at run time
by the asp.net host in IIS) into a class which inherits from your base
class. When this happens your code behind source file is nowhere to be found
(it is already compiled into the .dll)
