LINQ Insight Express

Introduction
  LINQ Insight Express is a Visual Studio add-in that offers useful tools for LINQ and ORM development.
       It provides tools for design-time LINQ query execution and preview of generated SQL and for profiling data access events from such ORMs as
Entity Framework, NHibernate, LinqConnect, and LINQ to SQL.

Supporting Version : VS 2010,2012,2013

I) Design-time LINQ Execution
II) LINQ Profiler

Design-time LINQ Execution
Benefits
Visual Studio Integration
Convenient Query Analysis
Design-time Operation
Support for Different Kinds of Queries
How to Use
     To view SQL for a LINQ query, perform the following steps:
     Right-click the query and select Run LINQ Query from the shortcut menu or place cursor over the query and press  CTRL+SHIFT+R.
     If your query depends on some variables, specify their values in the opened dialog box.

StringCollection Class

Represents a collection of strings.
StringCollection accepts Nothing as a valid value and allows duplicate elements.
String comparisons are case-sensitive.
Elements in this collection can be accessed using an integer index. Indexes in this collection are zero-based.

Syntax:

  Dim sColl As New StringCollection()
  Dim colArr() As String = {"RED", "GREEN", "YELLOW", "BLUE"}
      sColl.AddRange(colArr)

ListDictionary Class

Implements IDictionary using a singly linked list.
Recommended for collections that typically contain 10 items or less.
It is smaller and faster than a Hashtable
This should not be used if performance is important for large numbers of elements.

Members, such as Item, Add, Remove, and Contains are O(n) operations, where n is Count.

Syntax:

For Each direntry As DictionaryEntry In myListDictionary
  ...
Next direntry

PowerModes in Microsoft.Win32

• Resume The operating system is about to resume from a suspended state.
• StatusChange A power mode status notification event has been raised by the operating system. This might indicate a weak or charging battery, a transition between AC power and battery, or another change in the status of the system power supply.
• Suspend The operating system is about to be suspended.

Microsoft.Win32 Namespace

The Microsoft. Win32 namespace provides two types of classes: those that handle events raised by the operating system and those that manipulate the system registry.

SystemEvent Class

Provides access to system event notifications. This class cannot be inherited.

• DisplaySettingsChanged Event
• DisplaySettingsChanging Event
• EventsThreadShutdown Event
• InstalledFontsChanged Event
• LowMemory Event
• PaletteChanged Event
• PowerModeChanged Event
• SessionEnded Event
• SessionEnding Event
• SessionSwitch Event
• TimeChanged Event
• TimerElapsed Event
• UserPreferenceChanged Event
• UserPreferenceChanging Event

Expose Keys in Registry

CurrentUser
Stores information about user preferences.
LocalMachine
Stores configuration information for the local machine.
ClassesRoot
Stores information about types (and classes) and their properties.
Users
Stores information about the default user configuration.
PerformanceData
Stores performance information for software components.
CurrentConfig
Stores non-user-specific hardware information.
DynData
Stores dynamic data.

Anonymous Methods in C#

Anonymous Methods in C#
               C# supports delegates for invoking one or multiple methods. 
               Delegates provide operators and methods for 

•                              adding and removing target methods, and are used extensively throughout the .NET Framework for events, 
•                              callbacks, 
•                             asynchronous calls, 
•                              multithreading. 

             Anonymous methods is a new feature in C# 2.0 that lets you define an anonymous (that is, nameless) method called by a delegate.

Performance improvement in SQL Server

Performance improvement 

• Use shortest data type possible
• Make sure the data types of the columns participating in a JOIN are of same type
• Use Calculated columns instead of on the fly complex calculations 
• Consider using RCSI (read committed snapshot isolation) to preclude readers from blocking writers (writers will still block other writes but this is much graceful than using NOLOCK hints)
• Partition Alignment (64K or 1024k) and block size (or cluster size) of 64KB
• Keep the transactions as short as possible to preclude blocking/deadlocking/TLog  bloating issues
• If they need to trace, use server side trace
• If it is Ad hoc workload, consider turning on the "Optimize the Adhoc Workload" option
• Teach them how to figure out missing indexes from DMVs but add them only necessary - tweak the existing indexes first (make them composite and include columns)
• Minimize queries that use text searches, rather use full-text indexes on those columns
• Familiarize themselves with In-Memory OLTP feature
• Avoid float data types if you need accuracy
• Avoid nested views
• Familiarize with different granular levels of compilation
• Pitfalls of using HEAPS
• Revisiting the index configuration every few months
• Familiarize themselves with Blocked Process Report
• Using SET NOCOUNT ON, avoiding sp prefix, etc
• Parameter Sniffing 
• Using triggers sparingly
• Use of sp_executesql instead of EXEC
• Pros and cons of using natural keys vs surrogate keys
• Data growth and its adverse effects on query time and ways to mitigate them
• Avoiding all hints unless absolutely necessary
• No user prompts within explicit transactions
• Peer review and unit test the code before submission
• Caching rarely changing lookup table data on the client side to mitigate network chatter

Asynchronous Programming with Async and Await

Asynchronous Programming with Async and Await

• Asynchronous Programming is introduced in VS 2012.
• It's support .NET FRAMEWORK 4.5 and Windows Runtime.
• application retains a logical structure that resembles synchronous code.
• Asynchronous is essential for activities that are potentially blocking, such as when your application accesses the web.
• In an asynchronous process, the application can continue with other work that doesn't depend on the web resource until the potentially blocking task finishes.
• The Async and Await keywords in Visual Basic 
• By using those two keywords, you can use resources in the .NET Framework or the Windows Runtime to create an asynchronous method almost as easily as you create a synchronous method.
• Asynchronous methods that you define by using async and await are referred to as async methods.
• Async methods are intended to be non-blocking operations.
• An await expression in an async method doesn't block the current thread while the awaited task is running.
• Instead, the expression signs up the rest of the method as a continuation and returns control to the caller of the async method.

        End AddHandler

            RemoveHandler <Control Name>.<Event>, value
        End RemoveHandler

        RaiseEvent(ByVal sender As Object, ByVal e As System.EventArgs)
            For Each handler As EventHandler In _handlers
                Try
                    handler.Invoke(sender, e)
                Catch ex As Exception
                    Debug.WriteLine("Exception while invoking event handler: " & ex.ToString())

Hashing Algorithms

Hashing Algorithms
        Hashing is the process of mapping binary data of variable length to a fixed size binary data.

        Applying the same hash function to two identical data structures yields the same result. 

There are two kind of hashing algorithms : with or without a key.
The algorithms without keys are used only to calculate secure hashes for data to ensure integrity, whereas the keyed algorithm are issued together with a key as a MAC for bath integrity.

• ALGORITHM NAME:SHA1   DESCRIPTION :USES SHA ALGO WITH A RESULTING HASH OF 160 BITS
• ALGORITHM NAME: SHA256   DESCRIPTION :USES SHA ALGO WITH A RESULTING HASH OF 256 BITS
• ALGORITHM NAME:SHA 512   DESCRIPTION :USES SHA ALGO WITH A RESULTING HASH OF 512 BITS
• ALGORITHM NAME:SHA 384   DESCRIPTION :USES SHA ALGO WITH A RESULTING HASH OF 384 BITS
• ALGORITHM NAME:MD5   DESCRIPTION :USES MD5 HASH ALGORITHM
• ALGORITHM NAME:RIPEMD160 DESCRIPTION :USES RIPEMD HASH ALGORITHM
