How to host an ASP.Net application in a server where SharePoint 2013 is installed

Question

I have SharePoint 2013 with application url for example: https://intra.abc.org

now I have another (CarTracking) ASP.Net MVC application want to host it in this server

for example: https://intra.abc.org/CarTracking

but it give bellow error:

Server Error in '/CarTracking' Application.

Runtime Error

Description: An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine.

Details: To enable the details of this specific error message to be viewable on remote machines, please create a tag within a "web.config" configuration file located in the root directory of the current web application. This tag should then have its "mode" attribute set to "Off".

Notes: The current error page you are seeing can be replaced by a custom error page by modifying the "defaultRedirect" attribute of the application's configuration tag to point to a custom error page URL.

than I turned off the custom error and I get the following error

Server Error in '/CarTracking' Application.

Answer 1

There's two things to suggest here:

1. In IIS, at the folder level for "CarTracking", you need to create a new Application (in IIS-sense), so your app is hosted in a dedicated app domain (in the sense of .NET). You may also choose to host this new application in a dedicated app pool but that's not mandatory.

2. You need to edit your web.config file in "CarTracking" to add back all HTTP modules removed explicitly by SharePoint in its own web.config: AnonymousIdentification, FileAuthorization, Profile, WebDAVModule and Session. Also remove explicitely added modules. So, you'd end-up with somthing like this in your own web.config for your app:

   <add name="AnonymousIdentification" type="System.Web.Security.AnonymousIdentificationModule" />
   <add name="FileAuthorization" type="System.Web.Security.FileAuthorizationModule" />
   <add name="Profile" type="System.Web.Profile.ProfileModule" />
   <add name="Session" type="System.Web.SessionState.SessionStateModule"/>
   
   <remove name="SPNativeRequestModule" />
   <remove name="SPRequestModule" />
   <remove name="ScriptModule" />
   <remove name="SharePoint14Module" />
   <remove name="StateServiceModule" />
   <remove name="PublishingHttpModule" />
   <remove name="DesignHttpModule" />
   <remove name="FederatedAuthentication" />
   <remove name="SessionAuthentication" />
   <remove name="SPWindowsClaimsAuthentication" />
   <remove name="SPApplicationAuthentication" />
   <remove name="Session" />
