Using Dotnet CLI To Setup ASP.NET CORE Solution And Run With Tye
I have always created more complex solutions, which are more than 1 project, through the friendly and familiar UI of Visual Studio. Now we have had multiple version of dotnet core and we are about to receive .NET 5 by the end of the year I thought it would be fun to see if I can setup a more involved solution purely on the command line.

Experimenting with ASP.NET Core Authentication Schemes
Some software is easier to understand if you remove the software from it’s usual environment and try some experiments. ASP.NET Security components, for example. What is the impact of having multiple authentication schemes? Why does a ClaimsPrincipal have multiple identities? What does it mean to SignOutAsync on an HttpContext? You’ll never use the following code in a real application. But, you might use this code to tinker and experiment.

Use TempDataAttribute For Clean Code
In a previous post, I wrote about solving the form resubmission confirm issue that many developers run into when building web applications. In ASP.NET MVC, we have many tools at our disposal to pass information from one method to another, the most common being the TempDataProvider. In this short but enlightening post, we’ll take a look at how we can use a new feature in ASP.NET Core to clean up our usages of TempData.

Any() vs Count() in .NET: Which One is Better?
In this article, we are going to learn the main differences between Any and Count methods from LINQ. We work with different collections in C# all the time, and we often need to check if there are any records inside the collection or if it is empty. Both methods can help us to achieve that. We are going to see how each method works internally and compare the efficiency of each approach to determine which one we should use in specific use cases.
