Configuration Error in asp.net



While working with Asp.Net I got this error while trying to deploy my web site in the server. The full error message is given below:

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: Unrecognized attribute 'requestValidationMode'. Note that attribute names are case-sensitive.

Source Error:
Line 43:         timeout="60"
Line 44:         />-->
Line 45:     <httpRuntime maxRequestLength="10240" requestValidationMode="2.0"/>

Cause:
The main reason for this error is requestValidationMode is introduced in .Net 4.0. This problem will occur if your web server is setting to use .Net 2.0

Solution:
Change the dot net framework version settings to use .Net 4.0. Then you will not get this error.

Another way to resolve this is to use ValidateRequest like below:

<%@ Page="" ValidateRequest="false" %>
