Question

I have my gui which has this in its webconfig:

<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>

Now when i go in the IIS and within the website properties select the asp.net version of v2.0.50727 (as i can see no higher version).. everything works fine

but now when i use another server of win 2003 i get an error

Configuration Error

Description: An error occurred during the processing of a
configuration file required to service this request. Please review the
specific error details below and modify your configuration file
appropriately.

Parser Error Message: Child nodes not allowed.

at this line:

i saw some answers which said that the server must not have v3.5… but i have selected v2.0.50727 so why do i need v3.5, also then how did it work in the previous server..

Please help..
thanks

As far as ASP.Net is concerned, 3.5 is mostly just a set of extensions for the 2.0 runtime. You still use a .Net 2.0 App Pool to run web apps built with .Net 3.5. However, you do need to make sure that .Net 3.5 is installed on the server, or the extensions won’t be available.
