Presenting for the St. Louis .NET User Group – What’s new in VS2010 and .NET 4.0

Last night I had the pleasure of presenting a session on ‘What’s new in VS2010 and .NET 4.0’ for the St. Louis .NET User Group.  Got to meet with lots of people there, so greets go to all .  I had fun with the session; I liked talking about new technology and it’s pretty neat to see everyone and just mingle around with people in general.  Pizza was great (thanks to last night’s sponsor: Quilogy) – I have to also thank Scott Spradlin for allowing me to present to the group.

The session itself has the same presentation slide as my .NET 4.0 session which I presented in St. Louis Day of .NET, which I’ve made available as detailed in this post.  I did make a project that tries to also demonstrate some of the new constructs, which I didn’t have time to do when I first presented it.  So here it is.  It is a simple WinForms application, with 6 buttons, each of which demonstrates:

• Using the dynamic keyword to invoke a method, and also to provide a generic Add method which accepts 2 dynamic parameters
• Demonstrates support for consuming COM-Interop methods (opening up a Word document).  An MSDN howto article on this is available here.
• Using the BigInteger structure
• Using the Tuples constructs
• Demonstrate ConcurrentLinkedList<T> (thread-safe collections are in the System.Collections.Concurrent namespace)
• Demonstrate the use of FileDialogCustomPlace to add application-specific one-click shortcuts
• 
• It also has other files that demonstrates other features; the variance.cs file contains constructs that shows Covariance and Contravariance.

I hope this may be of use to others.

On a side note, based on the recommendation of speakers at the St. Louis Day of .NET, I’ve created a Twitter account: mulbud.  Hopefully I can contribute to Twitterverse in a positive way .
