Error: the selected file is a solution file but was created by a newer version 2010

Hi Guys
  I faced an issue while opening project solution using visual studio 2010 . It was showing an error -"Error: the selected file is a solution file but was created ...". I knew why this error was coming . it was just because i had opened this solution using visual studio 2012 and did certain modification and  checked in the solution. Microsoft visual studio has strange issue which is "Backward incompatibility" (Seriously strange!!) .When i opened this solution using visual studio 2010 it started throwing the error as mentioned above. So did some work around and fixed the issue as follows:

  1. Open the solution in NOTEPAD instead of visual studio 
  2. Edit the items as mentioned below
  •           Replace the format version from 12 to 11 and replace visual studio 2012 to 2010 as mentioned in the snapshot

Save the file and again open with visual studio 2010. It will start working fine

The server was unable to process the request due to an internal error. For more information about the error, either turn on IncludeExceptionDetailInFaults

Hi Guys,   I came across this issue  today. I was totally blank. Later i started observing the issue and realised that, this issue is caused just because of  mismatch of assembly version or any attribute  in Security token service's web.config file (C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\WebServices\SecurityToken). Actual issue was i upgraded the assembly version and didn't do changes in web.config file of security token service This blog helped me to fix my issue http://underthehood.ironworks.com/2011/05/sharepoint-2010-an-exception-occurred-when-trying-to-issue-security-token-the-server-was-unable-to-p-1.html thanks pradeepa achar

[Solution] :How to not serialize the __type property on JSON object

While working on ajax- webservice , most of the time we prefer return value from web service method should be in JSON format . If we expect a web service method to return the value as JSON object then it will display few information about the source code through the __type property. Also this property is additional load for response. We ideally need to avoid this property Have a look at the below image in which it is returning JSON object which has my custom properties along with __type property. Here i have used burp suite penetration testing tool to test the loophole in our software. Through fiddler i have got the information about request /response  and wanted to hide error message which gets generated from exception. Usually stack trace may allow hackers to  retrieve error message which  contains code related information by using which hacker can easily find the loophole to hack the function.So when  exception arises hacker should not be...
