Where do I have to make changes to make my application run?

Answer 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.

Answer 2

The error page pretty much tells you where the error lies and what is causing it.

I do not think that providerOption is a valid child element of the compiler element in version 2.0 of the framework. It is apparent from the information you have posted that your application is mapped to the version 2.0. If this is a problem, you should consider remapping the script map to v. 3.x.

AFAIK, this element is only available in .NET v3.x and above.
