3. Create a new console project
We created a new test1 folder under the C:\project\dotnet directory,The project name is named after the folder name by default。
Go to the test1 folder and execute the following commands in turn:
Starting with the .NET Core 2.0 SDK, there is no need to run dotnet restore because it is implicitly run by all commands that need to be restored, such as dotnet new, dotnet build, and dotnet run.
If you want to execute the compiled program, you can go to the \bin\Debug\netcoreapp2.1 folder of the project and run dotnet test1.dll.
3. Develop IDE tools
We recommend using VS Code as our development tool, and if you want to do it well, you must first sharpen your tools. Download Address:https://code.visualstudio.com/
After opening the project with VS code, the editor automatically installs 3 plugins, as follows:
