Before C# 6.0
In C# 6.0
Prior to C#6.0, we were using constructor to initialize the auto properties to non-default value. In C#6.0, you
can modify the Employee class and populate the property called EmployeeID with inline initialization.

4. Await in a Catch & Finally Block

In C# 6, now you can write
asynchronous code inside a
catch/finally block. This will help you
to log exceptions to a file or database
without blocking the current thread

5. Dictionary Initializer

In C# 5, you would initialize the Dictionary with a {“Key”, “Value”} Pair. Let’s look at below
example to understand it better. In C# 6, you can place the key between two square brackets
[“Key”] and then set the value of the key [“Key”] = “value”.

Exception Filters allow you to specify a condition for a catch block. In C#6.0, without entering the catch
block, you can check to see which condition met your exception.

7. Expression Bodied Function &
Property

Expression Bodied Functions are
functions with no statement body.
Instead, you implement them with
an expression following the
function declaration

8. Getter-Only Auto Properties

When you use auto implemented properties in C# 5 and lower, you must provide a get and set.
If you want the property value to be immutable, you can use the private accessor on the setter.
With C# 6, you can now omit the set accessor to achieve true readonly auto implemented
properties:

9. NameOf Expression

Name of Expression is a new feature introduced in C#6.0.In Enterprise level applications, we
handle exceptions at different levels. Showing a specific type name with an error message can
be an easy way to find the code block where the exception just occurred. But by adding this we
can’t show it to user because the type name can be changed anytime while refactoring but hard
coded string won’t change accordingly.

Most of us do not like NullReferenceException.
In C# 6.0, you can use ?. to check if an instance is null or not.

11. Static Using Syntax

In C# 6, you can now add the using static qualifier and reference the WriteLine
method by itself as shown above.

12. String Interpolation

String Interpolation is a mechanism to concatenate two or more strings together. In older versions of C#,
we were using “+” operator or String.Format method to concatenate strings but in C# 6.0, Microsoft has
provided a feature named String Interpolation to concatenate strings.
