以编程方式更改web.config：“ buildProviders”部分

Question

For deployment, I wrote a tool that modifies some web.config settings from development to production environments. That works well except in one case:

When I try to set debug to false , my buildProviders section disappears.

This is my system.web section:

  <system.web> <machineKey ... /> <compilation debug="true" strict="false" targetFramework="4.0"> <buildProviders> <remove extension=".resx"/> <remove extension=".resources"/> </buildProviders> <assemblies> ... </assemblies> </compilation> 

and this is my modification code:

    private void ChangeDebugSetting()
    {
        System.Configuration.Configuration configuration = System.Web.Configuration.WebConfigurationManager.OpenWebConfiguration("~");
        System.Web.Configuration.CompilationSection comp = (System.Web.Configuration.CompilationSection)configuration.GetSection("system.web/compilation");
        comp.Debug = false;
        configuration.Save();
    }

In the resulting web.config the buildProviders section is missing.

In the debugger I can see that the comp.BuildProviders collection is empty. However, a protected property base.Items contains two elements with _entryType = Removed and _key = ".resx" resp. _key = ".resources" .

How can I manage that both "remove" elements will be saved to web.config ?

Finally I solved my problem using classes of the System.Xml Namespace (XmlDocument, XmlElement etc.) instead of thje System.Configuration namespace.

This works fine.
