Metadata Function ها در SQL Server
To be able to make full use of the system catalog to find out more about a database, you need to be familiar with the metadata functions. They save a great deal of time and typing when querying the metadata. Once you get the hang of these functions, the system catalog suddenly seems simple to use, as Robert Sheldon demonstrates in this article.

نگاهی سریع به فریم ورک های MVVM
One year ago MVVM wasn’t very famous. I remember the first article I read about it, about using MVVM to simplify the management of treeview controls.

A .NET guideline specifies that an application should never throw a NullReferenceException
. However, many applications and libraries do. The NullReferenceException
is the most common exception happening. That’s why C# 8 tries to get rid of it. With C# 8, reference types are not null be default. This is a big change, and a great feature. However, what about all the legacy code? Can old libraries be used with C# 8 applications, and can C# 7 applications make use of C# 8 libraries?
This article demonstrates how C# 8 allows mixing old and new assemblies.
