Examples

This example demonstrates how to specify values declaratively for several attributes of the compilation section, which can also be accessed as members of the CompilationSection class.

The following configuration file example shows how to specify values declaratively for the compilation section.

<system.web>  
  <compilation   
    tempDirectory=""   
    debug="False"   
    strict="False"   
    explicit="True"   
    batch="True"   
    batchTimeout="900"   
    maxBatchSize="1000"   
    maxBatchGeneratedFileSize="1000"   
    numRecompilesBeforeAppRestart="15"   
    defaultLanguage="vb"   
    targetFramework="4.0"   
    urlLinePragmas="False"   
    assemblyPostProcessorType="">  
    <assemblies>  
      <clear />  
    </assemblies>  
    <buildProviders>  
      <clear />  
    </buildProviders>  
    <expressionBuilders>  
      <clear />  
    </expressionBuilders>  
  </compilation>   
</system.web>

The following code example demonstrates how to use members of the CompilationSection class.
