validateRequest and requestValidationMode dont work with .net 2.0
asp.net-2.0, validate-request, web-config
Solution
The requestValidationMode attribute was introduced in .NET 4.0.
Under .NET 2.0 you should only have to add `<pages validateRequest="false" />` to your Web.config to avoid Potentially Dangerous request errors.
You can also turn request validation off for an individual page using `<%@ Page ValidateRequest="false" %>`.
Problem
I am hosting WCF Service in IIS 7. They are running under .net version 2.0. Everything is working fine. But lately, i am getting error list "Potentially Dangerous request ...". I searched on the internet and found out have i have to set my web.config like this. ``` <system.web> <httpRuntime requestValidationMode="2.0" /> <pages validateRequest="false" /> </system.web> ``` I updated my web.config but then I am not able to browse to the services. It is giving me this error. Parser Error Message: Unrecognized attribute 'requestValidationMode'. Note that attribute names are case-sensitive. Please help me to resolve this error. Thanks, Vivek
