 Versions of Visual Studio IDE

Visual Studio is an integrated development environment from Microsoft. It is used to develop computer programs including

websites,

web apps,

web services,

windows applications,

console applications and mobile apps.

·       first version of VS IDE is, Visual Studio 97,  March-1997

·       latest version of VS IDE is, Visual Studio 2022  , Nov-2021 and last update given by Microsoft on June-2023(17.6.3) 



Visual Studio IDE is having below features for developers 


There are three editions of Visual Studio: 

·       Community : free, fully-featured IDE for students, open-source and individual developers

·       Professional : a subscription based option for individual developers or small teams.

·       Enterprise : a subscription based option for small to large business and enterprise organizations. 

subscription: The subscription business model is a business model in which a customer must pay a recurring price at regular intervals for access to a product or service.

 

To get download the visual studio we have to visit below website and choose the required edition of visual studio IDE and download. 

URL: https://visualstudio.microsoft.com/downloads/

 

Once we open the visual studio editor, we will get below screen with major windows.


 

Code Editor: Where the user will write code. 

Output Window: Here the Visual Studio shows the outputs, compiler warnings,                               error messages and debugging information.  

Solution Explorer: It shows the files on which the user is currently working. 

Properties Window: It will give additional information and context about the                                         selected parts of the current project.  

Project Templates

A project template is a project that includes work packages and actions that you know you will frequently apply to various projects.

To create new project, we have to choose from initial dash board or from File->New->Project

 


Item Template

Project and item templates are reusable stubs that give you some basic code and structure to customize for your own purposes. Typically, you start with a project template and then you add an item template

To add item to the existing project, select the relevant Project, right click and choose Add->New Item


Solution

A solution is simply a container  and Visual Studio uses to organize one or more related projects. When you open a solution, Visual Studio automatically loads all the projects that the solution contains.

 


 

Solution will get saved with extensions .sln(Solution file) with all the added projects inside of solution like in the above case it is ConsoleApp1.sln

Project

A project contains executable and library files that make up an application or component of an application.

 


When we add or create new project it will get add above files

Properties: This folder contains the AsseblyInfo details and where we can add the details of assembly like

References: C# project could uses several libraries as a reference. we put those reference libraries in a subfolder (e.g. folder named References)

 


Every project is saving with the extension .csproj(C# project) and for vb projects it would be .vbproj(VB project).

When we open this file after save, it will get load the relevant project files into Solution Explorer

 Compilation & Execution

Compile-time is the time at which the source code is converted into an executable code while the run time is the time at which the executable code is started running.

 

We can compile entire solution so that all projects under solution will get compiled at a time

To compile solution,

·       select Build menu like Build->Build Solution

·       select Solution and right click and choose Build Solution

 

To compile project,

·       select Project and right click and choose Build

 

Rebuild Solution: It will rebuild the solution

Clean Solution: it will clean or remove the already constructed solution file 

Once we compile the solution or project then it will create the relevant Project MSIL stuff like .exe or .dll

.exe , this will be created if it is a console application or windows application

.dll, this will be created other than console and windows application 

Differences between .exe and .dll

 


Execution

Once we compile then we have to execute to get the output.

To execute we have below options

·       Select Debug, Debug->Start Without Debugging 

·       Click on Start button from secondary tool bar 

Debug: In Debug mode, it will create .pdb(programmable database) file.

A pdb file is a program database file that's used to hold debugging information about a program or module.

Release : When we set this mode to project this only creates the relevant MSIL file like .exe or .dll but not .pdb file. 

While deploying on client space, we must always build the project in Release mode.

Email Sending through O365 using OAuth Protocol

  Microsoft Office365 EWS servers have been extended to support authorization via the industry-standard OAuth 2.0 protocol. Using OAUTH protocol, user can do authentication by Microsoft Web OAuth instead of inputting user and password directly in application Microsoft / Office 365 OAuth + EWS We can use the OAuth authentication service provided by Azure Active Directory to enable our application to connect with IMAP, POP or SMTP protocols to access Exchange Online in Office 365. To use OAuth with our application we need to register application on Azure Active directory and other steps also we need to do to get the access token back. Below are the steps   To use Microsoft/Office365 OAUTH in your application, you must create an application in  https://portal.azure.com . Sign into the Azure portal using either a work or school account or a personal Microsoft account. If your account gives you access to more than one tenant, select your account in the top right corn

IISRESET vs App Pool Recycling ?

-

 I think most IIS administrators know IISRESET command, and why they use it. One of possible reasons can be to restart IIS services to initialize web applications, or to apply some changes of applications & IIS settings .There’re just a few conditions those need your IISRESET command. In most situations, you don’t need this. I have a concern if you always run this command for applying any changes, or release system resource – memory – regularly, or frequently. Because it’s much more cost than what you really need to take – there’re side effects Recycling App Pool’ has been introduced from IIS6 in Windows2003. It’s designed to restart only application pools(=worker processes). It can be done in a command prompt(run ‘IISAPP /?’ in a command prompt for details), as well as in the IIS manager What IISRESET does? When you run IISRESET, many things will happen. In order to understand them, I think I need to show you how IIS looks like – about IIS core components. The below shows you role

Deploy .Net6.0 Web api with docker

  What is Docker? Docker is a containerization platform, meaning that it enables you to package your applications into images and run them as “containers” on any platform that can run Docker. It negates the classic: “It works on my computer” argument as Docker images contain everything needed for the app to run. Are Containers the same as Virtual Machines? They are similar, but not the same. In short: Virtual Machines provide OS Level Virtualization Containers provide App Level Virtualization This concept is depicted below: Why Would You Use it? In short you would use Docker, (and hence containers), for the following reasons: Portability.  As containers are self- contained  they can run on any platform that runs Docker, making them easy to stand up and run on a wide variety of platforms. Scalability.  With the use of additional “orchestration” you can spin up multiple container instances to support increased load. Performance.  Containers generally perform better than their VM counterp
