Error: could not load file or assembly or one of its dependencies

[=?Utf-8?B?U2hlaWxh?=]

Hi,

Does anybody encounter this error:
Unhandled Exception: System.IO.FileL oadException: could not load file or
assembly or one of its dependencies. Access is denied.

I google the error and found a few resolutions, such as exclude Temporary
ASP.NET Files folder from virus scan, grant full rights to Temporary ASP.NET
Files folder, etc. all doesn't work.

Previously the application works fine if all dlls are deployed in GAC, but
after I move dll to application Bin folder, the problem happens. To make the
website up, I have to clear all content in Temporary ASP.NET Files folder,
but after a few runs, it happenes again. Right now the only soultion works
for me is to set trust level to full in web.config, which I don't want to do
due to security reason.

Does anybody know what could be the cause? thanks in advance.

Hi Michael,

The website is hosting a few customized server controls, thus its difficult
to post all code here. I just show you how a assembly (common library) is
normally called in the code

....
using Company.Common;

....
CommonFunction Com = new CommonFunction( );
if (Com.IsCorrectC ategory(output, NewsCategories) )
{
PageList = ContentPublishi ng.GetAllPageLi st(SiteID,
Com.GetNewsCate goryID(SiteNews Category,NewsCa tegories).ToStr ing(), null,
_startDateTime, _endDateTime);
}
...

Is there any article I can read on this? thanks.

Regards
Yu Ping
