Fatal Error When Running .Net Application from UNC FileShare

[DotNetWWW]

Hi all , I have a .Net Application that is going to be used in a workgroup environment , I installed the app on the server machine and the suftware runs successfully and connects to sql server with no problem , I also installed prerequisites such as .Net framework 2.0 on lient computer and shared the app folder which is located on server machine . on client machine , When I want to run the app from UNC FileShare I get fatal error that asks to send error to microsoft , but when I copy the entire folder from UNC FileShare to local client , the app connects to server successfully and user can work with software. What's is the problem in your opinion? Note : I also made the shared folder FullControl and also adjusted Entire Zone in Microsoft .Net Framework 2.0 Configuration to FullTrust(On Server machine) , What causes this problem you think? Thanks in advance (Emergency!)

It's called "Code Access Security". Any code running from a non-local (i.e.: Shared folder or other network source) is NOT trusted by default. You have to tell the .NET CLR to trust the code comming from a certain source. Read this[^] post and follow the three links in it.
