Provides an easy way to create sequential guids

GuidUtils.cs

	using System;
	using System.Runtime.InteropServices;
	using System.Security;

	public static class GuidUtil
	{
		[SuppressUnmanagedCodeSecurity]
		[DllImport("rpcrt4.dll", SetLastError = true)]
		private static extern int UuidCreateSequential(out Guid value);

		/// <summary>
		/// Creates a new sequential guid.
		/// </summary>
		public static Guid CreateSequential()
		{
			Guid guid;
			Marshal.ThrowExceptionForHR(UuidCreateSequential(out guid));

			return guid;
		}
	}

These sequential guids are only reliable while the app/session is not restarted :(
