Question

I am developing an MVC application using nHibernate; running through VS’s built in web server the application runs without errors. When setup and running through IIS7 on localhost, the application throws a SQlClientPermission exception after calling System.Data.SqlClient.PermissionDemand (SqlClient calls this internally)

I have enabled the application to run under full trust but it doesn’t seem to affect the outcome.

Answer 1

From the description, I’m guessing that you’re using Integrated Security in your connection string. Maybe something along the lines below.

Data Source=myServerAddress;Initial Catalog=myDataBase;Integrated Security=SSPI;

When running through VS built in web server, it runs under your credentials and that’s why it works.

To get this to work on IIS, either

1. Create a new IIS app pool which runs
   under your credentials
2. Or, use sql authentication.

(Let me know if you like me to expand further)
