Question 1. What Is Net Dynamics Application Server?
Net Dynamics Application Server became an early Java-based totally incorporated software platform. Product become developed by way of Net Dynamics, a Silicon Valley begin-up agency based in 1995 via Zack Rinat and Ofer Ben-Shachar. Other early software server competition, Net Dynamics selected Java as development language for platform.
Question 2. What Is Dynamicobject?
The DynamicObject magnificence allows you to define the dynamic behavior for an object at run time. This class cannot be instantiated immediately; therefore, to implement the dynamic behavior, you need to inherit from the DynamicObject elegance and override the necessary techniques. It permits you to define the specific operations that may be executed on dynamic items as well the methods to carry out those operations.

Question 3. Explain The Difference Between Dynamic And Var Data Types?
The difference among the var and dynamic information kinds is that the var statistics kind is strongly type checked on the collect time; whereas, the dynamic records type is kind checked by using the compiler only at run time. After putting forward a var records kind, you can't explicitly trade its type at some stage in the execution of this system; however, a variable of the dynamic information kind may be modified for the duration of runtime. Another fundamental difference between the 2 is that dynamic type also can be used as the go back type for methods, for which var can't be used.
Question four. What Is Expandoobject?
The ExpandoObject class refers to a category whose participants can be explicitly introduced and eliminated at runtime. In other phrases, the ExpandoObject class allows dynamic binding of the objects, which permits you to use preferred syntax, similar to the dynobj.Method approach as opposed to using greater complicated syntax, such as dynobj.GetAttribute("Method").

Question five. Which Class We Used To Convert The Data Types?
The System.Convert magnificence affords a complete set of methods for changing the records sorts.

Question 6. What Is Python Binder?
Python Binder enables to communicate with IronPython.
Question 7. What Is Middleware Net Dynamics?
NetDynamics Application Server turned into the primary Java-based totally included software platform. The product became developed by NetDynamics Inc. As Java became the dominant improvement language for net-primarily based programs, NetDynamics skilled tremendous revenue growth in 1997 and 1998. However, the product soon encountered problems due to the relative immaturity of Java and the frenzy to release new product variations in a hastily converting marketplace

Question eight. Explain And Distinguish Between Reflection And Dynamic?
Both mirrored image and dynamic are used while we need to perform on an item in the course of runtime.
Reflection is used to investigate meta-information of an object. It additionally has the ability to invoke members of an object on runtime.
Dynamic is a key-word which changed into brought in .NET 4.Zero. It evaluates item calls during runtime. So until the technique calls are made compiler is least afflicted if the ones techniques / homes and so on exist or not.
Dynamic makes use of mirrored image internally. It caches the technique calls made therefore improving performance to a positive extent.
Reflection can invoke each public and personal participants of an item whilst dynamic can handiest invoke public individuals.
Question nine. What Is Dynamic Language Runtime (dlr)?
DLR is a runtime environment that permits you to combine dynamic languages with the Common Language Runtime (CLR) with the aid of including a set of services, such as expression trees, name website caching, and dynamic object interoperability to the CLR.

Question 10. What Is System.Dynamic?
The System.Dynamic and System.Runtime.CompilerServices namespaces are used to maintain the lessons for DLR. It also offers dynamic functions to statically-typed languages, such as C# and Visual Basic to enable their interoperation with dynamic languages.
Microsoft Dynamics CRM Tutorial
Question eleven. List The Advantages Of Dlr?
Allows you to easily implement the dynamic languages to the .NET Framework.
Provides dynamic functions to statically-typed languages. The statically-typed .NET Framework languages, along with C# and Visual Basic can create dynamic gadgets and use them collectively with statically-typed items.
Implements sharing of libraries and gadgets, because of this that the items and libraries applied in one language may be used by different languages using DLR. The DLR also allows inter-operation among statically-typed and dynamic languages.
Enables speedy execution of dynamic operations by helping boost caching.

Question 12. What Are Dlr Binders?
Binders are used by DLR to talk with not the .NET Framework but additionally with various other services, consisting of Silverlight and COM. These offerings constitute language-specific semantics and specify how a particular operation can be performed at the call web page.

Question 13. What Things Are Performed By Dynamic Objects?
Call sites discuss with the area in the code where logical and mathematical operations, consisting of a + b or a.B() are achieved on dynamic gadgets.

Question 14. What Is Expression Trees Services Provided By Dlr To Clr?
Refers to the illustration of code in a facts shape much like a tree. However, expression bushes in DLR are the superior version of the expression bushes that were added with LINQ in .NET 3.5. Therefore, DLR has prolonged the functionalities of Language Integrated Query (LINQ) expression bushes, inclusive of manipulate glide, assignment, and other language-modeling nodes to a dynamic language. These expression bushes outline the semantics of a language in shape of an summary syntax tree (AST). AST permits the DLR to dynamically generate code, which the CLR executes at runtime.
Question 15. What Is Call Site Caching Services Provided By Dlr To Clr?
Enables the DLR to keep the information of the operations and traits of the variables, along with their statistics type. The call web page caching services also allows to check whether or not such operations have been achieved previously to retrieve all the information approximately the variable. The place in which DLR stores those values is called a name web page.

Question sixteen. What Is Dynamic Object Interoperability Services Provided By Dlr To Clr?
Enables the DLR to provide a set of training and interfaces that constitute dynamic objects and operations. These lessons and interfaces may be used to create classes for dynamic libraries, which may be utilized in static and dynamic type languages.
Question 17. List The Names Of Binders Provided By .Net Framework 4.Zero?
.NET Framework 4.Zero offers the following binders:
