The ASP.NET ViewState is a client side state management. ViewState is stored in hidden field with ID named __VIEWSTATE. Typically, stored ViewState information looks as below:
Now let us look at the value. It looks likes an encrypted string. This is nothing but Base64 Encoded string and it is not an encrypted string. So it can be easily decoded.
The main reasons for making it Base64 encoding are as follows:
1. Base64 makes a string suitable for HTTP transfer
2. It makes it a little harder to read .
But people often get confused that this is an encrypted string.

One of the common tasks involved in the development is GUID’s generation. This is even more frequent when we are working on a SharePoint solutions. Even during writing unit test we need to 
generate static GUID to validate data’s. Visual Studio comes with a tool called guidgen.exe ( c:\program files (x86)\microsoft sdks\windows\v7.0a\bin\NETFX 4.0 Tools\guidgen.exe ) which is registered with visual studio as an external tool and invoked from Tools > Create GUID. But whenever you need an unique static GUID you have to navigate to tool and copy the ID evertime. Last few days of my development involved with lots of GUID generation where I found it’s taking time to generate so many guid’s. So, I came up with an small approach where we can generate a GUID by just pressing some shortcut key. Behind the seen I wrote a macro for the same and that is being triggered with the key press.

To answer this question In a single statement, you can use HttpContext.Current.Items for very short term storage. By Short term storage means, this data is valid for a single HTTP Request. There are many confusion around regarding storing data in HttpContext.Current.Items and storing data in Session variable. In this blog post I am going to describe what are the different scenarios where we can use HttpContext.Current.Items and what is the exact difference with session variable.
Items collections of HttpContext is and IDictionary key-value collections and that are shared across a single HTTPRequest. Yes, HttpContext.Current.Items valid for a single HTTPRequest. Once after processing, server information is sent back to the browser, the variables that were set in the Items[] collection will lost. Where as for Session Variable, information valid for multiple request as this is user specific. The session variable only expires either on Session Time Out or explicitly clear the values.

Visual Studio having great features to set breakpoint in multiple functions at same time. For most of the time, to set a breakpoint with in a function you just put a breakpoint in the first line of the function.

During debugging of your application, you may need to keep track of some data which are already out of scope. Say, You call a MethodB() from MethodA() and did some operation inside MethodB(), now when you returned back to MethodA(), all the local variables inside MethodB() are
out of scope. But you want to use them in MethodA(). Now here is the trick, that you can create an ObjectID for an member variables or objects and can track the same when it’s out of scope as well, but until GC() does not collect it. In this post, I am going to explore how we can use an Out of Scope object value to deal with Conditional Break points. To start with, first you have to understand how to use Object ID to track and out of scope object. Here is my complete article How to track an object which is Out of Scope while Debugging ? . Though I described a quick look into use of out of scope object inside conditional breakpoints on that article, I received few query about more details on the same. So here I am going to give some more details.

In one of my previous blog post, Identifying Worker Process (w3wp.exe) – IIS 6.0 and IIS 7.0 for Debugging ASP.NET Application - I have explained about how we can identify the list of currently running worker process using command prompt while we need to attach process from visual studio . But do you know for IIS 7.0 and IIS 7.5 we can get the worker process (w3wp.exe) details like Application Pool name, Process ID, CPU Usages from IIS Manager itself. Even you can get details of each worker process for a “Web Garden” scenarios. So when you need to attach some process for debugging from Visual studio, Instead of going to command prompt, you can easily identify the worker process Id from IIS itself.

Most of the time we use Visual Studio find combo box (
) only for search contents with in the solution. But the find combo box is something more than what we know. We can use the find combo box in different purpose like create file, open files, create project, print, open watch windows etc. As for example you can close all the open files by just typing “>CloseAll” with in find combo box followed by a “Enter”. Fundamentally we can execute all the commands from Find Combo box which are available from Visual Studio Command Window. Like Command Window, In Combo Box, if you type “>” and aliases and press enter result will be the same.

In Mastering in Visual Studio 2010 Debugging article I have discussed about the basic of Object ID creation while debugging. I received some request from some readers to explain the use of “Make Object ID” in details. In this blog post I am going explain how we can track an Object which is already out of scope using by creating a Object ID while debugging.
By using “Make Object ID” option we are informing Visual Studio Debugger to keep track of that object no matter it’s within scope or out of scope for the current context. We can create “Object ID” either from Locals, Autos or from Watch Windows. Object ID is a integer number followed by a pound (#) sign. When we create Object ID for an particular object, Visual Studio Debugger ( CLR Debugging Services ) use an integer value to uniquely identify the object. This “Object ID” allows you to get the object details even if it is out of scope.
