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 able to know the i

I have head started with python programming language which is one of the oldest programming languages . It is has OOPS concept so that if we are familiar with OOPS concept then this programming language should be quite easy for us to learn. Only syntax varies.

while deploying the solution using visual studio you may get this error -"Error occurred in deployment step 'Recycle IIS Application Pool': The local SharePoint server is not available. Check that the server is running and connected to the SharePoint farm. " Solution:   Hint for the solution is in the error message itself. It is not able to connect to sharepoint server means it is not able to communicate to  database instance. i.e the instance might have stopped. So goto SQL Server configuration manager. Click on start and search for "SQL Server configuration manager". You should know that the sharepoint installed to which instance? In my case it is sql server(sharepoint). It was stopped. Just start the instance by right click on that and select Start option. Now start deploying the solution from visual studio Hope this may help someone thanks pradeepa achar
