Ambiguous assemblies / DLL

I was trying to implement URL re-writing as described in approach #3 here: http://weblogs.asp.net/scottgu/archive/2007/02/26/tip-trick-url-rewriting-with-asp-net.aspx

I'm quite sure I know what the problem is here, but no clue how to fix it.  I know from the error and searching online that basically my app DLL is conflicting with my temp .net files DLL, but I can't seem to figure out how to clear it.

I cleared my app DLLs
I cleared my temp DLLs
I deleted my bin folder
I checked my namespace was right
I Google'd every possible thing I could think of

I didn't rename the class (because I don't believe I should have to do that or want to)

I'm such a bone head! I was using the App_Code folder in a web application and that was the reason it was causing the conflict. As soon as I renamed the folder to something else, compiled fine.

You have 2 dll's with the same "qualified name", but which may differ by filename, that are accessible to your application. Have you installed anything to the GAC? There are two paths described in the error message and you should clear those paths of any conflicting DLLs.

And you are right, you shouldn't have to rename the class   = )

I don't think I'm using the GAC, if I am, I didn't do it willingly.

Now I've tried clearing the DLL's with no luck before.

Would using the publickeytoken on <adapter controlType="System.Web.UI.HtmlControls.HtmlForm" adapterType="HotAtNight.FormRewriterControlAdapter" /> have any affect? (not that it would matter, the sn.exe file isn't on my computer and I've looked in all the SDK folders.)

Did you try clearing the files in C:\Users\Michael\AppData\Local\Temp\Temporary ASP.NET?  Safe to empty that folder.  If you've got a web project you can right-click on the project in the Solution Explorer and choose clean.

Yea, I've tried both methods. No luck.
