Glimpse ASp.NET and Dapper.NET

Question

Can anyone shed any light on the use of Glimpse with Dapper, or is it purely just for Entity Framework?

EDIT

 public List<UserRole> GetUserRoles(string userName)
    {
        using (var block = new TransactionBlock())
        {
            const string sql = "SELECT AspNetRoles.Name FROM AspNetUsers INNER JOIN " +
                               "AspNetUserRoles ON AspNetUsers.Id = AspNetUserRoles.UserId INNER JOIN " +
                               "AspNetRoles ON AspNetUserRoles.RoleId = AspNetRoles.Id " +
                               "WHERE (AspNetUsers.UserName = @userName)";
            var results = TransactionBlock.Connection.Query<UserRole>(sql, new{userName}, transaction: TransactionBlock.Transaction).ToList();
            block.Commit();
            return results;
        }
    }

Answer 1

Ah, thanks for the TransactionBlock code, which shows immediately why Glimpse is not intercepting any DB calls.

Try making use of the DbProviderFactories class by changing the following lines :

var localConnectionString = ConfigurationManager.ConnectionStrings["DefaultConnection"].ConnectionString;
var conn = new SqlConnection(localConnectionString);       

with

var localConnectionString = ConfigurationManager.ConnectionStrings["DefaultConnection"];
var factory = DbProviderFactories.GetFactory(localConnectionString.ProviderName); 
var conn = factory.CreateConnection();

Have you tried using the Glimpse.ADO package as well?
