My thoughts on TechEd 2014 announcements

Are you following this? Are you watching the videos? I think Channel9, the official Microsoft media outlet, died from overwhelming demand. The cynics may say that this is because of technical issues, however, I say that this is due to a highly demanding audience :). If you have been unable to watch the live stream, rest assured that all recordings will be available online soon (usually withing 48hrs).

Resolving “HttpContextWrapper is not serializable” errors after upgrading Glimpse.

If you are doing any ASP.NET development and not using Glimpse you are seriously missing out. It helps is so many ways to troubleshoot and improve performance that I cannot believe how I’ve done any web development without in the past.

Using an Smtp client in ASP.NET MVC 4 and C#
