  1. providerOption is not allowed as Child node in the compiler tag of the web.config.

    <system.codedom>     <compilers>             <compiler language='c#;cs;csharp' extension='.cs' warningLevel='4' type='Microsoft.CSharp.CSharpCodeProvider, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'>                     <providerOption name='CompilerVersion' value='v3.5'/>                     <providerOption name='WarnAsError' value='false'/>             </compiler>     </compilers> </system.codedom>

    See here on the MSDN docmentation for the .NET 3.5 framework.
