C# Internal Keyword Explained

In C#, the internal keyword is used to specify that a class, method, property, or field can only be accessed within the current assembly. Essentially, this means that only other classes within the same assembly can access internal members, while classes in different assemblies cannot. This access level is typically used to restrict the scope of certain members, allowing them to only be used within the current assembly without exposing them externally. internal is the default access modifier in C#, so if an access modifier is not explicitly specified, members are by default internal.
