An assembly is a file that is automatically generated by the compiler upon successful compilation of every .NET application. It can be either a Dynamic Link Library or an executable file. It is generated only once for an application and upon each subsequent compilation the assembly gets updated.
Keeping this in consideration, what is an assembly and its use?
Defined by Microsoft for use in recent versions of Windows, an assembly in the Common Language Infrastructure (CLI) is a compiled code library used for deployment, versioning, and security. There are two types: process assemblies (EXE) and library assemblies (DLL).
What is the difference between assembly and namespace in C#?
System.Data is a namespace, System.Data.DLL (the file) is an assembly. A namespace is a logical grouping of types (mostly to avoid name collisions). An assembly can contain types in multiple namespaces ( System.DLL contains a few), and a single namespace can be spread across assemblies (e.g. System.Threading ).
What is the use of assembly in asp net?
An assembly is a collection of types and resources that forms a logical unit of functionality. Each time you create a Microsoft Windows® Application, Windows Service, Class Library, or other application with Visual Basic .NET, you’re building a single assembly. Each assembly is stored as an .exe or .dll file.
What is GAC in c# net?
The Global Assembly Cache (GAC) is a folder in Windows directory to store the .NET assemblies that are specifically designated to be shared by all applications executed on a system. Assemblies can be shared among multiple applications on the machine by registering them in global Assembly cache(GAC).
What is the use of DLL in C#?
Stands for “Dynamic Link Library.” A DLL (.dll) file contains a library of functions and other information that can be accessed by a Windows program. When a program is launched, links to the necessary .dll files are created. If a static link is created, the .dll files will be in use as long as the program is active.
What is manifest in net?
The assembly manifest contains this assembly metadata. An assembly manifest contains all the metadata needed to specify the assembly’s version requirements and security identity, and all metadata needed to define the scope of the assembly and resolve references to resources and classes.
What is an assembly in asp net?
Assemblies are the building blocks of .NET Framework applications; they form the fundamental unit of deployment, version control, reuse, activation scoping, and security permissions. An assembly is a collection of types and resources that are built to work together and form a logical unit of functionality.
What is the difference between an EXE and a DLL?
Difference between exe and dll-1.EXE is an extension used for executable files while DLL is the extension for a dynamic link library. 2.An EXE file can be run independently while a DLL is used by other applications. 3.An EXE file defines an entry point while a DLL does not.
What is the use of metadata in C#?
it means it hold information about a data that is your html page. When we talk in terms of C#, Metadata is stored in one section of a .NET Framework portable executable (PE) file, while Microsoft intermediate language (MSIL) is stored in another section of the PE file. Metadata tables reference other tables and heaps.
What is a satellite assembly in net?
A satellite assembly is a .NET Framework assembly containing resources specific to a given language. Using satellite assemblies, you can place resources for different languages in different assemblies, and the correct assembly is loaded into memory only if the user selects to view the application in that language.
What is the CLR in C#?
The Common Language Runtime (CLR), the virtual machine component of Microsoft’s .NET framework, manages the execution of .NET programs. A process known as just-in-time compilation converts compiled code into machine instructions which the computer’s CPU then executes.
What is a strong named assembly?
A strong name consists of the assembly’s identity—its simple text name, version number, and culture information (if provided)—plus a public key and a digital signature. A strong-named assembly can only use types from other strong-named assemblies.
What is the GAC?
GAC is the short version of “Global Assembly Cache”. It is a common place in the OS where assemblies that are going to be shared between different applications can be stored. The .NET assemblies are there, for one.
What is the use of namespace in C#?
First, the .NET Framework uses namespaces to organize its many classes, as follows: C# System.Console.WriteLine(“Hello World!” ); System is a namespace and Console is a class in that namespace.
What is the garbage collection in C#?
When you create any object in C#, CLR (common language runtime) allocates memory for the object from heap. GC (Garbage collector) makes a trip to the heap and collects all objects that are no longer used by the application and then makes them free from memory.
What is a DLL in net?
A .dll file contains compiled code you can use in your application to perform specific program functions and may be required by another application or module (such as .exe or .dll) to load it through an entry point. It is a library that contains code and data that can be used by more than one program at the same time.
What is an assembly in the government?
Assembly. government. Assembly, deliberative council, usually legislative or juridical in purpose and power. The name has been given to various ancient and modern bodies, both political and ecclesiastical.
What is the difference between a namespace and assembly name?
Difference between NameSpace and Assembly. A .Net Namespace provides the fundamental unit of logical code grouping while an assembly provides a fundamental unit of physical code grouping. Namespaces is a logical group of related classes that can be used by any other language targeting the Microsoft .Net framework .
What was the role of the Roman Assembly?
The Roman Assemblies were institutions in ancient Rome. They functioned as the machinery of the Roman legislative branch, and thus (theoretically at least) passed all legislation. Since the assemblies operated on the basis of direct democracy, ordinary citizens, and not elected representatives, would cast all ballots.
What is assembly in manufacturing?
An assembly line is a manufacturing process (often called a progressive assembly) in which parts (usually interchangeable parts) are added as the semi-finished assembly moves from workstation to workstation where the parts are added in sequence until the final assembly is produced.
What is the assembly language?
1949. An assembly (or assembler) language, often abbreviated asm, is a low-level programming language, in which there is a very strong (but often not one-to-one) correspondence between the assembly program statements and the architecture’s machine code instructions.
What is an assembly at school?
A school assembly is a gathering of all or part of a school for any variety of purposes, such as special programs or communicating information on a daily or weekly basis. In some schools, students gather to perform a common song or prayer, and to receive common announcements.
What are the delegates in C#?
A delegate in C# is similar to a function pointer in C or C++. Using a delegate allows the programmer to encapsulate a reference to a method inside a delegate object. The delegate object can then be passed to code which can call the referenced method, without having to know at compile time which method will be invoked.
