将我的ASP.NET MVC4发布到主机后，使用角色提供程序获取配置错误

Question

I'm developing an ASP.NET MVC4 web application. I'm using entity framework, and my database is in my host (i'm using HostGator). I changed the RoleProvider to be in this database as well (instead of the default MVC configuration). My website works just fine in my computer (using VS2012), but when I tried to upload all the website to HostGator, i'm getting this exception:

Server Error in '/' Application.

Iv'e been trying so many things, but I just don't know what should I do... Thanks a lot!!

Answer 1

The first problem seems to be related to Entity Framework rather than the web.config. As you can see in the stack trace the constructor for your provider is being called:

at RFProject.Models.Bussiness.RFProviders..ctor()

but then you have other errors (you have to look above that line, not below). Maybe some problem with the Entity Framework version used by HostGator?

The second problem is because some web.config settings can be (and are) defined at server level (IIS here I imagine) and sometime they can be set as "non-overridable". This seems to be the case with HostGator and the <trust ...> setting. Nothing you can do except have a chat with them...
