When you modify the configuration for any delegated feature, Internet Information Services (IIS) 7.0 removes custom values in the Web.config file.

For example, consider the following scenario. The following information is part of the Web.config file:

<applicationSettings>
    <TestObject.Settings>
      <setting name="TestSetting" serializeAs="String">
        <value>TestValue</value>
      </setting>
    </TestObject.Settings>
</applicationSettings>

You take one of the following actions:

• You modify a delegated feature from the user interface (UI).
• You modify the Appcmd.exe file.
• You modify programmatic means.

In this scenario, the information in the Web.config file changes to the following:

<applicationSettings>
    <TestObject.Settings>
      <setting name="TestSetting" serializeAs="String">
        <value></value>
      </setting>
    </TestObject.Settings>
</applicationSettings>
