Are dynamic types bad?
The short answer is YES, it is a bad practice to use dynamic. Why? dynamic keyword refers to type late binding, which means the system will check type only during execution instead of during compilation. It will then mean that user, instead of programmer, is left to discover the potential error.
Why is dynamic typing useful?
Advantages of dynamically-typed languages: More succinct/less verbose. The absence of a separate compilation step (which is much more common) means that you don’t have to wait for the compiler to finish before you can test changes that you’ve made to your code. Even a 10-second compile step tends to add up over time.

What is Dynamic C#?
C# 4 introduces a new type, dynamic . The type is a static type, but an object of type dynamic bypasses static type checking. In most cases, it functions like it has type object . At compile time, an element that is typed as dynamic is assumed to support any operation. The call causes a compiler error.
Are there any shortcomings of using dynamic types in C #?
Are there any specific shortcomings apart from wrong dynamic method calls which throw run time exceptions which developers must know before starting the implementation. The main shortcoming is that you throw away one of the main properties (not necessarily advantages) of C# – that it is statically typed (and for most part type safe).
Which is an example of a dynamic type?
A dynamic type escapes type checking at compile time; instead, it resolves type at run time. A dynamic type can be defined using the dynamic keyword. Example: dynamic type variable. dynamic dynamicVariable = 1; The compiler compiles dynamic types into object types in most cases.
How is a dynamic variable created in C #?
The compiler does not check the type of the dynamic type variable at compile time, instead of this, the compiler gets the type at the run time. The dynamic type variable is created using dynamic keyword. In most of the cases, the dynamic type behaves like object types.
How does dynamic type change at run time?
The dynamic type changes its type at the run time based on the value present on the right-hand side. As shown in the below example. When you assign a class object to the dynamic type, then the compiler does not check for the right method and property name of the dynamic type which holds the custom class object.
