ASP.Net Web API : adding appSettings

Question

I am migrating a web service from WCF service to ASP.Net Web API. When I try to add the following section to web.config, I get a page with error "Internal Server Error" when I try to run the application locally

<appSettings>
    <add key="Environment" value="production" />
    <add key="CacheEnabled" value="true" />
  </appSettings>

When I remove this section, the error goes away. Can you please tell me how to add appSettings to a Web API project?

Answer 1

The following can be a guide on how to do it, verify that your appSettings are inside configuration

<configuration>
  <appSettings>
    <add key="Key" value="Value"/>
  </appSettings>
</configuration>

To get the values of the key from the application you can do

textBox1.Text = ConfigurationManager.AppSettings["Name"];

Answer 2

Your appSettings needs to to into the Web.config under the configuration element as per the MSDN docs:

<configuration>
      <appSettings />
</configuration>

1. Make sure it's in the right element
2. Make sure there isn't already an existing appSettings tag

Otherwise, you would need to pass on the exact error message.
