Description eetasoft 2014-11-29 13:57:12 UTC
dynamic property returned by webmatrix from npgsql is case sensitive.

Steps to reproduce:

1. Create ASP.NET MVC 4 application using Microsoft Webmatrix.Data.dll and Npgsql with controller:

        public ActionResult CaseTest()
            using (var db = Database.OpenConnectionString(ConnectionString(),
                var vaik = db.QuerySingle("select 'Test' as Test");
                return new ContentResult() { Content = vaik.Test };

        static string ConnectionString()
            NpgsqlConnectionStringBuilder csb = new NpgsqlConnectionStringBuilder()
                SearchPath = "public",
                Host = "localhost",
                Database = "postgres",
                UserName = "postgres",
            return csb.ConnectionString;

2. Invoke controller CaseTest method in linux

controller shoudl return Test

In .NET 4 in Windows it produces expected result.
