What should I do if I encounter the "configuration system failed to initialize" error?

There are two common causes for this error:

One is, in the config file, configsections is not placed on the top, see the following blog explanation: http://blogs.msdn.com/jongallant/archive/2008/03/02/configuration-system-failed-to-initialize-one-possible-solution.aspx

The other one is that the user. config file is damaged when the configuration items in the user scope are included ......, The user. config file is generally in: C: \ Documents ents and Settings \ [username] \ Local Settings \ Application Data \ [appcompany] \ [appname] \ [appversion] \

Of course, you can find it through View details in the error dialog box in the debug debugger of. For more information, see: http://thesprage.com/DasBlog/2008/05/23/ConfigurationSystemFailedToInitialize.aspx

I encountered the second situation, but I haven't done it for a long time.
