At the end of the course, you will know what are the main new features of C# 12 and how to use them in your projects

Some of the topics that we will see in the course are:

Primary Constructors
Collection Expressions
Optional parameters for lambdas
Param array parameters for lambdas
Alias any type
Among other topics

To have a good use of the course, it is recommended to have basic knowledge of C#
