Updated on: March 12, 2021

Follow the below Steps to create .NET Core application and run it from any IDE like Visual Studio Code:

Required tools to be downloaded and installed on the machine before development of .NET Core application:

1. .NET Core SDK

2. Any editor like Visual Studio, Visual Studio Code or Notepad 

Steps to begin with creation of .NET Core application:

Step 1: Test whether .NET Core is installed on the machine with the following command which can be run on the Command Prompt of the machine: 

dotnet --version

If it gives error like "'dotnet' is not recognized as an internal or external command, operable program or batch file.", then you should confirm whether .NET Core SDK is installed or not, if not, install it from .NET Core SDK

Step 2: Now, create the .NET Core Console / Web Api / Blazor app with the following command:

To create .NET Core Console app run following command:

dotnet new console -o ConsoleTestApp1

To create .NET Core Web Api App run following command:

dotnet run


The above command should run the project, now we opened the URL https://localhost:5001/ on the browser, it is showing following output:

You can try creating .NET core application using above steps. Because .NET Core is cross platform, you can create .NET Core apps on Windows, Linux, Mac machines.
