How to detect Clone Code in Visual Studio?

Code clones are separate fragments of code that are very similar. They are a common phenomenon in an application that has been under development for some time. Clones make it hard to change your application because you have to find and update more than one fragment.

Visual Studio Enterprise can help you find code clones so that you can refactor them.

You can either find the clones of a specific fragment, or find all clones in your solution. In addition to discovering direct copies, the clone analysis tool can find fragments which differ in the names of variables and parameters, and in which some statements have been rearranged.

The code clone analyser searches for duplicate code in Visual C# and Visual Basic projects throughout your Visual Studio solution.

DLL hell is the problem that occurs when an installation of a newer application might break or hinder other applications as newer DLLs are copied into the system and the older applications do not support or are not compatible with them. .NET overcomes this problem by supporting multiple versions of an assembly at any given time. This is also called side-by-side component versioning.

Posted Date:- 2021-11-11 14:54:29

Explain about Assembly and Manifest?

An assembly is a collection of one or more files and one of them (DLL or EXE) contains a special metadata called Assembly Manifest. The manifest is stored as binary data and contains details like versioning requirements for the assembly, the author, security permissions, and list of files forming the assembly.

An assembly is created whenever a DLL is built. The manifest can be viewed programmatically by making use of classes from the System.Reflection namespace. The tool Intermediate Language Disassembler (ILDASM) can be used for this purpose. It can be launched from the command prompt or via Start> Run.
