Element Description


Specifies the required root element in every configuration file that is used by the common language runtime and the .NET Framework applications.


Specifies the root element for the ASP.NET configuration section.


Configures all compilation settings that ASP.NET uses to compile applications.

The codeSubDirectories element defines an ordered collection of subdirectories that contain files to compile at run time.

Subdirectory names are relative to the App_Code directory.

The build order is inferred from the top-down order of the codeSubDirectories collection. The App_Code directory is built last. However, there are no build order dependencies, which means that the build order is not significant.

There is no default codeSubDirectories element configured for ASP.NET.

The following code example shows how to define an ordered collection of assembly subdirectories. The subdirectories are listed in the order that the code must be compiled that is function of your code dependencies.

           <add directoryName="mySubDir1"/>
           <add directoryName="mySubDir2"/>
           <add directoryName="mySubDir3"/>
