I upgraded dnn from v4.5.5 to v4.8.1. The upgrading process is smooth and the website workes.  I use install page for updading.   But now I can't build it for module development.  Can someone help?  Here is the error message:

I'm not sure how you're doing your module development but I'm assuming you're just referencing the DNN .dlls that you need in an Install version versus a Source version.

Anyways, there were major changes from DNN 4.5 to 4.6 with the authentication process and I'm wondering if you've tried updating your references to the DNN dlls.

Yes, I never use source version for my module development.  I am using VS2005 for programming.   I still can modify the code on my own modules but  the custom classes in App_code folder can't take affect after modification.  I think I can building .a dll from separate project.

Would you let me know which DNN dlls I should check for the latest authentication process?  All the dlls in v4.8.1 install package are copied to /replaced with old one in bin folder. 

Thanks,
