i have the following web.config and everything was fine until i added role provider.

i have two connection strings defined and code in my asp.net application to detect what machine is running the web app and pull the correct DB connection string for the environment (dev/ prod)

now i added role provider and everything is working but the definition in the web.config links the roles provider to a single DB in its declaration.

below is the section of my web.config in question.

how can i make it such that the roles in both DEV and PROD are independent and isolated as they should be???

Create a new role provider that inherits the existing one and override the Initialize() method to set the connection string to the desired value. For example, add this class to your project:

namespace MyNamespace
{
      public class MyRoleProvider : SqlRoleProvider
      {
            public override void Initialize(string name, System.Collections.Specialized.NameValueCollection config)
            {
                  base.Initialize(name, config);

                  // Set to desired connection string name
                  string connectionStringName = "ISConnectionString_test";

                  string connectionString = System.Configuration.ConfigurationManager.ConnectionStrings[connectionStringName].ConnectionString;

                  // Set private property of Membership provider.
                  FieldInfo connectionStringField = GetType().BaseType.GetField("_sqlConnectionString", BindingFlags.Instance | BindingFlags.NonPublic);
                  connectionStringField.SetValue(this, connectionString);
            }
      }
}

Then replace your existing role definition in web.config with this:

<roleManager defaultProvider="MyRoleProvider">
      <providers>
            <clear />
            <add name="MyRoleProvider"
                        type="MyNamespace.MyRoleProvider"
                        connectionStringName="name of a real but dummy connection string from the connectionStrings section that will never actually get used. Its value could just be 'x'"
                        ... remaining properties...
            />
      </providers>
</roleManager>

i added the following and it seems not to work. i added a break point to the class to check if it was pulling the correct connectionString and the break point does not get hit. what did i miss?

i try to detect the port and if it is not port 80 then use the dev connectionString, if it is port 80 then use the prod version


 
namespace STAR
{
    public class STARRoleProvider : SqlRoleProvider
    {
        public override void Initialize(string name, System.Collections.Specialized.NameValueCollection config)
        {
            base.Initialize(name, config);

            string connectionStringName = HttpContext.Current.Request.Url.Port == 80 ? "ISConnectionString_prod" : "ISConnectionString_test";
            // Set to desired connection string name
            
            string connectionString = System.Configuration.ConfigurationManager.ConnectionStrings[connectionStringName].ConnectionString;

            // Set private property of Membership provider.
            FieldInfo connectionStringField = GetType().BaseType.GetField("_sqlConnectionString", BindingFlags.Instance | BindingFlags.NonPublic);
            connectionStringField.SetValue(this, connectionString);
        }
    }
}



<roleManager defaultProvider="STARRoleProvider">
      <providers>
        <clear />
        <add name="STARRoleProvider" type="STAR.STARRoleProvider" connectionStringName="x" applicationName="PMIS"/>
      </providers>
</roleManager>

Sorry, I forgot to include the enabled setting. In web.config, the first line should look like this:

<roleManager enabled="true" defaultProvider="STARRoleProvider">

I copied your code into one of my projects and confirmed it worked after making this change.
