Microsoft Visual Studio Interview Questions
Visual Studio Interview Questions # 6) What is Refactoring?
A) Refactoring is the process of improving your code after it has been written. Refactoring changes the internal structure of the code without changing its behavior.
Visual Studio Interview Questions # 7) What are the different Refactoring options in Visual Studio?
A) The different refactoring option in visual studio are:
- Add parameter (from CallSite)
- Generate overrides
- Add named argument
- Add null-check for parameters
- Insert digit-separators into literals
- Change base for numeric literals (for example, hex to binary)
- Convert if-to-switch
- Remove unused variable
Visual Studio Interview Questions # 8) How do you interact with Git in Visual Studio?
A) When you are working with a project in Visual Studio, you can set up and quickly commit and publish your code to a Git service. You can also manage your Git repositories by using menu clicks from buttons in the bottom right-hand corner of the IDE.
Visual Studio Interview Questions # 9) What are the benefits of Azure Functions Tools?
A) The Azure Functions Tools provides the following benefits:
Edit, build, and run functions on your local development computer.
Publish your Azure Functions project directly to Azure.
Use WebJobs attributes to declare function bindings directly in the C# code instead of maintaining a separate function.json for binding definitions.
Develop and deploy pre-compiled C# functions.
Pre-compiled functions provide a better cold-start performance than C# script-based functions. Code your functions in C# while having all of the benefits of Visual Studio development.
Visual Studio Interview Questions # 10) What’s the advantage of creating a project in Visual Studio for a Python application?
A) Python applications are typically defined using only folders and files, but this structure can become complex as applications become larger and perhaps involve auto-generated files, JavaScript for web applications, and so on. A Visual Studio project helps manage this complexity.
The project (a .pyproj file) identifies all the source and content files associated with your project, contains build information for each file, maintains the information to integrate with source-control systems, and helps you organize your application into logical components.
.NET Visual Studio Interview Questions And Answers
Visual Studio Interview Questions # 11) Can you explain about browser link?
A) Browser Link is a new feature in Visual Studio 2013 that creates a communication channel between the development environment and one or more web browsers. You can use Browser Link to refresh your web application in several browsers at once, which is useful for cross-browser testing.
Visual Studio Interview Questions # 12) Can you explain about Namespace?
A) Namespaces are logical groupings of names used within a program. There may be multiple namespaces in a single application code, grouped based on the identifiers’ use. The name of any given identifier must appear only once in its namespace.
Visual Studio Interview Questions # 13) Explain about Assembly and Manifest?
A) 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.
Visual Studio Interview Questions # 14) Do you know about DLL Hell? Explain it?
A) 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.
Visual Studio Interview Questions # 15) What is CLR?
A) Common Language Runtime (CLR) is a run-time environment that manages the execution of .NET code and provides services like memory management, debugging, security, etc. The CLR is also known as Virtual Execution System (VES).
Advanced Visual Studio Interview Questions For Experienced
Visual Studio Interview Questions # 16) What is Architecture Explorer in Visual Studio?
A) use Architecture Explorer in Visual Studio to find specific code.
Visual Studio Interview Questions # 17) How to detect Clone Code in Visual Studio?
A) 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.
Visual Studio Interview Questions # 18) How to generate Sequence diagrams in Visual Studio?
A) To visualize how the code implements a particular method, create a sequence diagram from that method in Visual Studio Ultimate. The sequence diagram shows the interaction between objects as a series of lifelines and messages.
Lifelines represent instances of objects, and messages represent method calls between those objects. You can generate sequence diagrams from Visual C# .NET or Visual Basic .NET code, but not from projects that share code across multiple apps.
Visual Studio Interview Questions # 19) What is the use of The Code Definition window in Visual Studio?
A) Keyboard: CTRL + \, D
Menu: View -> Code Definition Window
Command: View.CodeDefinitionWindow
Versions: 2008,2010
Ever want to just click on a reference and see the definition as you go? Well it’s time to get reintroduced to the Code Definition Window.
Visual Studio Interview Questions # 20) Shortcut Keys for debugging in Visual Studio?
A) Visual Studio Debugging Shortcut Keys:
Ctrl-Alt-V: A Displays the Auto window to view the values of variables currently in the scope of the current line of execution within the current procedure
Ctrl-Alt-Break: Temporarily stops the execution of all processes in a debugging session. Available only in run mode
Ctrl-Alt-B: Displays the Breakpoints dialog, where you can add and modify breakpoints
Ctrl-Alt-C: Displays the Call Stack window to display a list of all active procedures or stack frames for the current thread of execution. Available only in break mode
Ctrl-Shift-F9: Clears all of the breakpoints in the project
Ctrl-Alt-D: Displays the Disassembly window
