ConfigurationManager.AppSettings Caching

by

A quick test seems to show that these settings are only loaded at application startup. //edit the config file now.

Console.ReadLine(); Console.WriteLine(ConfigurationManager.AppSettings[“ApplicationName”].ToString()); Console.ReadLine(); You’ll see that all outputs remain the same.

System.Configuration.ConfigurationManager not available?

by

Although the using System.Configuration; command is automatically generated in the using section, for some reason the actual reference is not set. Go into add reference, .Net tab, and choose System.Configuration. ConfigurationManager will now be resolved. If you go to the project where the exact same setup works just fine and look at the references, you … Read more

Error: The name ‘ConfigurationManager’ does not exist in the current context

by

You need to reference System.Configuration.dll in your project as well as the “using” statement. Namespaces are (sometimes) “split” across assemblies. That means that types in a single namespace are actually in different assemblies. To determine which assembly a BCL or FCL type is in, look it up on MSDN. If you look at the help … Read more

What’s the difference between the WebConfigurationManager and the ConfigurationManager?
