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" %>
