Security exception

Question

Here I published my MVC web application, but it cannot be opened due to a security exception error.

I tried using <trust level="Full" /> and <securityPolicy> . If I applied one of them to a Security Exception solution, it shows a Configuration Error:

I would be grateful for your help if you have an alternative way to solve this problem.

Answer 1

This is very similar to the security issue your IIS is experiencing, can you see if your web application has permissions on the folder or application pool?

Answer 2

Enable anonymous authentication mode in project properties
and in the Web.Config file add

 add key="enableSimpleMembership" to value="true" add key="autoFormsAuthentication" to value="true" 

Hope this works.
