I have a WinForms application with an embedded MapPoint control that I've been maintaining for about 5 years now. The application originally used MapPoint 2004, then 2006, and now we're upgrading to 2010. Within my development environment (VS2008/.NET 2.0 for the project) the application runs fine. Once I create an installer and insta...
I am getting the error message “The remote server returned an error: (501) Not Implemented.” when I try to use the HttpWebRequest.GetResponse() using the GET Method to get an email attachment from exchange.

I'm currently working on my first WPF application, and I'm curious as to whether I'll hit a snag down the line with performance by doing something like this: Dim binding As New Binding("PropertyOnObject.Property1.Property2.Value") binding.Source = Object vs doing Dim binding As New Binding("Value") binding.Source = Object.PropertyOnO...

It saves me the trouble from having to pass around an instance of the object to every little class in the project. However, now I need to manage multiple instances of the previous setup, which means that the singleton pattern breaks since each...

On a recent question about MVC attributes, someone asked whether using HttpPost and HttpDelete attributes on an action method would result in either request type being allowed or no requests being allowed (since it can't be both a Post and a Delete at the same time). I noticed that ActionMethodSelectorAttribute, from which HttpPostAttr...
So the other day my C# application crashed. Usually, with a .NET application, if you have an unhandled exception you get a nice error message with a stack trace. However, this time, I got a different dialog that just told me there was an error and offered to attach a Debugger, but there was no stack trace in the dialog and the machine ...

I am working on a client server system, and am running into issues where multiple clients are executing an action at the same time. We are able to solve this by locking on the critical section of code, which ensures that the first client will complete the action before the second client enters the code block. My question is this: our se...

I understand that System.DirectoryServices is a "layer above" System.DirectoryServices.Protocols and abstracts some of the complexity. Are there any other advantages, performance or otherwise, to using System.DirectoryServices.DirectorySearcher vs. System.DirectoryServices.Protocols.SearchRequest for LDAP queries from .NET. What crit...

This works under the .net framework 3.5 client. This fails under the .net framework 4.0 client. Was I doing something that was illegal under 3.5 but just happened to work, or is this a bug? Note that in my project 'PropInt' does not raise change events so using ctx[obj1.PropObj2, "PropInt"] is not an option. public class Obj1 { ...
