C# 7.0 adds a number of new features and brings the focus on data consumption, code simplification and performance. Perhaps the most interesting feature is tuples, a finite ordered list of values, of possibly different types, which is used to bundle related values together without having to create a specific type to hold them. Tuples are very good for performance reasons, as you don’t…
Some really easy ways to improve performance in your asp.net core web application are: response caching, which adds cache-related headers to responses, to reduce the number of requests a client makes to your web server; compressing response using gzip to reduce its size. You may start with the default asp.net core web application, apply the above steps and check the result. Setup…

In Entity Framework when you want to insert multiple items in your database you usually add your objects in your DbSet and then call context.SaveChanges at the end. This action, you may think, performs bulk inserts in your db but in reality things are a bit different. In the following example, we are going to generate multiple objects from our model Products and try to…
What is AutoMapper? AutoMapper is a simple little library built to solve a deceptively complex problem – getting rid of code that mapped one object to another.
