  How can I execute some code when my program experiences a fatal error and crashes? For example, something goes wrong and the box pops up that say “TestApp.exe has encountered an error and needs to close.” and then I want to write to a file with an error code and say a report of the last few things that were entered into the program. How would I do this in C#??

  c# windows-services
  I created a windows service and installer that watches a collection of files for changes and copies any file that changes to a destination directory specified in the WatchlistConfig.xml file. I have a couple issues with the service: 1. It has stopped running on one occasion. (unacceptable) 2. We sometimes have to attempt to start the service several times before it “takes”.I believe issue #1 is probably due to not handling fatal errors in the application. I found a bit of code that I tried to

  We have recently upgraded a project to MVC 3 Tools and discovered that our inversion of control container is causing problems with the native MVC model binding validation on both client- and server-side.

  In ASP.NET MVC 2, the lifespan of an entry in the TempDataDictionary was just one HTTP Request.That translated to setting a value in one request, redirecting, and having access to the same item at the other end of the line. After this the entry would be no longer available, regardless of whether you read the value out of the dictionary at the latter end of the line or not.Since ASP.NET MVC 3 (I believe), this implementation detail has changed quite significantly.Entries in the TempDataDictionary
