Visual Studio Project Sample Loading Error: Assembly could not be loaded and will be ignored. Could not load file or assembly or one of its dependencies. Operation is not supported. (Exception from HRESULT: 0x80131515)

Some folks have mentioned to me that they are having trouble getting some of my samples to work.  And in fact, just the other day, I ran into a problem getting my own samples to work.  It turns out to be a problem with the way windows treats the sample that you down load.   Specifically, because you downloaded the sample from the internet, windows treats the sample as “untrusted” content.  When you unzip untrusted content you get a directory full of untrusted content.  Visual Studio is not so good and running untrusted content.  Unfortunately, you get some really bad error messa...

AJAX Usage Among .NET Developers in 2009: Survey

A couple of years ago Simone Chiaretta did a survey of .NET Developers usage of Ajax..   I just saw that he is refreshing that survey to see what has changed in the industry.  Are people still actively moving to Ajax? Are they using MVC or WebForms with their Ajax?  Which ones of the *many* ajax frameworks out there are they using?  Feel free to write-in Silverlight if that is your current preference for this style of application. Very interesting data… and while clearly not a scientific survey, it is an interesting data point as Simone has agreed to publish all the data he gets. ... (more)
