How to generate controller using dotnetcore command line

by

This is the new way since mid 2018

You have to install dotnet-aspnet-codegenerator.
This is now done globally and not through a Nuget package:

PowerShell:

dotnet tool install --global dotnet-aspnet-codegenerator

Then this is how you create a REST-Controller from an existing EF Model in PowerShell:

dotnet-aspnet-codegenerator -p "C:\MyProject\MyProject.csproj" controller -name MyDemoModelController -api -m My.Namespace.Models.MyDemoModel -dc MyDemoDbContext -outDir Controllers -namespace My.Namespace.Controllers

Some helpful calls

Show available generators (-p... -h):

dotnet-aspnet-codegenerator -p "C:\MyProject\MyProject.csproj" -h

Show available options of the “controller” generator (-p... controller -h):

dotnet-aspnet-codegenerator -p "C:\MyProject\MyProject.csproj" controller -h

Generate controllers for many models in a loop

This is how you would generate REST controllers for all models in a given path from a PowerShell:

Get-ChildItem "C:\MyProject\Models" -Filter *.cs | 
Foreach-Object {
    $scaffoldCmd = 
    'dotnet-aspnet-codegenerator ' + 
    '-p "C:\MyProject\MyProject.csproj" ' +
    'controller ' + 
    '-name ' + $_.BaseName + 'Controller ' +
    '-api ' + 
    '-m My.Namespace.Models.' + $_.BaseName + ' ' +
    '-dc MyDemoDbContext ' +
    '-outDir Controllers ' +
    '-namespace My.Namespace.Controllers'

    # List commands for testing:
    $scaffoldCmd

    # Excute commands (uncomment this line):
    #iex $scaffoldCmd
}
