Creating a Hello World Application and Run on it in Windows

We are going to discuss, how to develop, build and run the apps with a different way such as Command line, Visual Studio, Visual Studio Code Editor, etc. We will see the step by step guidelines for .NET Core Hello World app creation, given below-

Use Command line procedures, given below-

1. Open cmd.exe (run as Administrator).
   
   
2. Type mkdir HelloWorldApp and Enter in the command line.
   
   
3. Type cd HelloWorldApp and Enter in the command line.
   
   
   
   
4. Type dotnet new and Enter in the command line, given below-
   
   
   
   
5. Type dotnet restore and enter in the command line, given below-
   
   
   
   
6. Type dotnet run and enter in the command line, given below-
   
    

Using Visual Studio 2015 procedures, given below-

 

Open Visual Studio 2015. Go to File menu, point to new and click new project. New Project Window will open, you can select an installed template like “.NET Core” in Visual C# Template and then select a Console Application (.NET Core) and type Project Name HelloWorldApp. Choose the project location path and click OK button.

 

 

Now, you can see HelloWorldApp project structure, shown in the screenshot, given below-

 

You can write a Hello Word program and run it
