• Lambda expressions

• Extending properties

• Global using statements

• File scoped namespaces

• Structs got the freedom

• Seal .ToString() for records

• Constant interpolated strings

1. Lambda Expressions

Lambda expressions are used to create anonymous functions , I love to use them for simple getter/setters e.g. GetFullName , Get Address etc. But lambdas have limitations with var types which were entertained in C# 10.

2. Extending Properties

Extending property was introduced in C# 8.0 , it allow a property sub patterns to reference nested members, for instance

3. Global Using Statements

You would have seen your code loaded with a lot of using statements at the top , and some of statements are repeated in multiple files. Since C# 10 now we can get rid of them through following ways

• Either make a global class and define using statements in it

• Include your using statements in .csproject file

4. File Scoped Namespaces

Now we can get rid of of namespaces and use file scoped namespaces.

5. Structs Got The Freedom

Now structs can have parameter less constructor opposite to previous one like this.

with can be used for structs as well now

6. Seal .ToString() For Records

Before C# 10 we could not apply sealed keyword for ToString override against records but now we can do that.

Above mentioned feature was added in C# 10 for records.

7. Constant Interpolated Strings

If you don’t know let me remind you that we use $ with for our strings and then using we can define our variables that is string interpolation.

Previously we were unable to do this thing with constant strings , but now we can achieve it.
