Application Security Change for Medium Trust

Recently I uploaded a system I created in Asp.Net using MVC and Entity to the KingHost web server. On localhost and on my own server it works normally. When trying to access the application on the KingHost server, it gives the following error:

  

[SecurityException: Type permission request failed   'System.Web.AspNetHostingPermission, System, Version = 4.0.0.0,   Culture = neutral, PublicKeyToken = b77a5c561934e089 '.]

  System.Web.HttpApplicationFactory.GetSpecialApplicationInstance (IntPtr   appContext, HttpContext context) +336
  System.Web.Hosting.PipelineRuntime.InitializeApplication (IntPtr   appContext) +296

By searching I could see the following: On the server you can configure the security policies in Web.config that is in the% windir% \ Microsoft.NET \ Framework {version} \ CONFIG \ directory of the server (even in localhost vc can set this). Usually looks like this:

<location allowOverride="true">
  <system.web>
    <securityPolicy>
      <trustLevel name="Full" policyFile="internal" />
      <trustLevel name="High" policyFile="web_hightrust.config" />
      <trustLevel name="Medium" policyFile="web_mediumtrust.config" />
      <trustLevel name="Low" policyFile="web_lowtrust.config" />
      <trustLevel name="Minimal" policyFile="web_minimaltrust.config" />
      <trustLevel name="Custom" policyFile="web_CustomTrust.config" />
    </securityPolicy>
    <trust level="Full" originUrl="" /> <--aqui eu digo o nível que as app vão usar-->>
  </system.web>
</location>

My default application was created as Full Trust. As the KingHost server is set to Medium Trust, in my application's web.config I would only need to set the security level of my application to Medium by placing this block:

<system.web>    
    <trust level="Full"/> 
</system.web>

However, on KingHost's server they set "allowOverride = false", not allowing the application to choose which level of security it wants to use through Web.config. I can see this because after I put this code it appears this other error message:

  

This configuration section can not be used in this path. That   occurs when the site administrator blocks access to this section   using 1 startup) +30 Microsoft.Owin.Host.SystemWeb.OwinHttpModule.InitializeBlueprint() +70 System.Threading.LazyInitializer.EnsureInitializedCore(T& target, Boolean& initialized, Object& syncLock, Func of a configuration file   inherited.

Does anyone know how I can change my application to Medium Trust?
