MVC 3 WebConfigurationManager.AppSettings["key"] returns null

May be it's a stupid but seems mvc has a bug with web.configs.

I put in Web.config (also I've tried to put keys in web.debug.config) several appsettings keys But 

ConfigurationManager.AppSettings["key"];

as well 

WebConfigurationManager.AppSettings["key"];

returns null.

I looked via debugger in AppSettings.AllKeys - it sees the right keys but returns the null.

What is the problem with AppSettings in mvc?

oh, I've found the mistake. The problem was in key names, keys were created using copy-paste and it is not noticeable when some keys have the space before closing ", for example key="HPPRequestUrl "

In your webconfig you should have something like this:

<configuration>
 <appSettings>
  <add key="key" value="x" /> 
 </appSettings>
</configuration>

And then you can retrieve your value by wrtiting:

WebConfigurationManager.AppSettings["key"];

Probably you have a cyrillic "C" character or a typo in the key name. Try to copy the key name from the AllKeys property using debugger.
