I have an ASP.NET Application that i want to deploy on the production server. my application has crystal reports in it. every thing works fine on my development station. once i move all required files to production and try opening the page i get error messages based on what dlls i have in the bin directory. if i don&#039;t have crystaldecision dlls in my bin directory i can open my pages but not the one with Crystal report. if i don&#039;t have crystal dlls in my bin directory i cannot open any page.<BR><BR>my question is what all dlls if needed should be in the bin directory if i have crystal reports in an application.<BR><BR>Thanks,<BR>AJ.
