Get this wierd compiler error on my production machine after publishing the
site in VS 2005, have no idea what it is..removed the temp files and it just
remakes them.

Compiler Error Message: CS0433: The type '_Default' exists in both
'c:\WINDOWS\Microsoft.NET\Framework\v2.0.50215\Tem porary ASP.NET
Files\testpopoff\90b00d8e\4772ca2f\assembly\dl3\a9 d383b3\5a6f804f_a7ebc501\App_Web_5n48zyrm.DLL'
and 'c:\WINDOWS\Microsoft.NET\Framework\v2.0.50215\Tem porary ASP.NET
Files\testpopoff\90b00d8e\4772ca2f\assembly\dl3\80 314b0c\b1d1824f_a7ebc501\App_Web_mb4c_l8p.DLL'

You have 2 assemblies (ddl files) within the same web application bin folder
named _Default. This could happen if another ddl had a web page named
default.aspx whose codebehind was compiled in that ddl but you (or someone
else) replaced the default.aspx whose codebehind was in another assembly.

(Correction) ... containing 2 class definitions ...

In your case you can solve this problem by changing the class name..

Sometimes this messeage can occur when there is a version conflict... If someone have 2 reference same dll with different versions.

In visual studio 2005 right click your web site and check "References" in properties.

You can remove the old version dll reference...
