NET core command-line interface (dotnet-cli) is a new NET Core toolset (commands) for developing NET Core Applications. The dotnet-cli toolset provides a list of pre-installed dotnet core project templates from which the user can create various applications as the dotnet core Console app, Web application, WPF (Windows Presentation Foundation) application, Windows Form application, and other test applications. The application created with dotnet-cli can be executed on any Windows, Linux or macOS operating system.
How to create “dotnet core console app“

Command Usage Example:
1. “dotnet new console”
This above command is used to create a new “dotnet core console application”. As the name of the application is not specified in the command so the project will be created by the name of the directory the command is executed in it. This command also performs an implicit restore of dependencies required for the project.
C:\temp>dotnet new console The template "Console Application" was created successfully. Processing post-creation actions... Running 'dotnet restore' on C:\temp\temp.csproj... Restoring packages for C:\temp\temp.csproj... Generating MSBuild file C:\temp\obj\temp.csproj.nuget.g.props. Generating MSBuild file C:\temp\obj\temp.csproj.nuget.g.targets. Restore completed in 141.06 ms for C:\temp\temp.csproj. Restore succeeded.
2. “dotnet new console –name “Hello”
The command creates a “Hello” directory only if doesn’t exist and then creates a “dotnet core console application” in it, the name of the project file is “Hello.csproj”. The command also performs an implicit restore of dependencies required for the project.
C:\>dotnet new console --name "Hello" The template "Console Application" was created successfully. Processing post-creation actions... Running 'dotnet restore' on Hello\Hello.csproj... Restoring packages for C:\Hello\Hello.csproj... Generating MSBuild file C:\Hello\obj\Hello.csproj.nuget.g.props. Generating MSBuild file C:\Hello\obj\Hello.csproj.nuget.g.targets. Restore completed in 157.63 ms for C:\Hello\Hello.csproj. Restore succeeded.
3. “dotnet new console –name “Hello” –no-restore”
The command creates a “Hello” directory only if it doesn’t exist and then creates the “dotnet core console application” in it, the name of the project file is “Hello.csproj”. The command does not perform any restore operation and create only two files viz: Hello.csproj and Program.cs. The content of the Hello directory is given below
C:\>dotnet new console --name "Hello" --no-restore The template "Console Application" was created successfully C:\Hello>dir Volume in drive C is Windows Volume Serial Number is 945D-A84B Directory of C:\Hello 06/12/2019 10:17 PM <DIR> . 06/12/2019 10:17 PM <DIR> .. 06/12/2019 10:17 PM 178 Hello.csproj 06/12/2019 10:17 PM 187 Program.cs 2 File(s) 365 bytes 2 Dir(s) 42,173,321,216 bytes free
