If you get the following error when using the Microsoft.ApplicationBlocks.ExceptionManagement library: System.Security.SecurityException: The event source ExceptionManagerInternalException does not exist and cannot be created with the current permissions. ---> System.Security.SecurityException: Requested registry access is not allowed. at System.ThrowHelper.ThrowSecurityException(ExceptionResource resource) at Microsoft.Win32.RegistryKey.OpenSubKey(String name, Boolean writable) at System.Diagnostics.EventLog.CreateEventSource(EventSourceCreationData sourceData) at System.Diagnostics.EventLog.CreateEventSource(String source, String logName) at Microsoft.ApplicationBlocks.ExceptionManagement.DefaultPublisher. VerifyValidSource() One way of solving this is to install the Microsoft.ApplicationBlocks.ExceptionManagement.dll by running the following in a dos window: C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\InstallUtil.exe Microsoft.ApplicationBlocks.Exception
Was playing around with generics and suddenly my unit test project failed with this error: “Signature of the body and declaration in a method implementation do not match.” After some research I found a post here http://social.msdn.microsoft.com/Forums/en-US/vststest/thread/b54e6634-1542-4bd8-a227-029bfb679dec that explained my problem was using a private on a generic class, and was a known bug that will not be fixed in VS 2010 as explained here https://connect.microsoft.com/VisualStudio/feedback/ViewFeedback.aspx?FeedbackID=415357 . Changed the private to public and was able to carry on.
I created my first WCF REST service the other day and was getting a 404 error when I deployed the service to our server. After some research I found the solution here: http://www.west-wind.com/weblog/posts/2008/Apr/10/WCF-REST-Configuration-for-ASPNET-AJAX-and-plain-REST-Services I needed to add: Factory ="System.ServiceModel.Activation.WebServiceHostFactory" to MyService.svc <% @ ServiceHost markup. There is also a very good write up on WCF REST service design here: http://msdn.microsoft.com/en-us/library/dd203052.aspx
