Roslyn from command line('cmd'), Windows 10 scenario example:
( Note: No need Visual Studio installed, but only the .NET core )
Open 'cmd' and create folder "dotnet-csharp-tools":
D:>mkdir "dotnet-csharp-tools"
Navigate to folder "dotnet-csharp-tools":
D:>cd "dotnet-csharp-tools"
In folder "dotnet-csharp-tools" download 'nuget.exe' latest version from:
https://www.nuget.org/downloads
Check name of the last version of 'Microsoft.CodeDom.Providers.DotNetCompilerPlatform' from:
https://www.nuget.org/packages/Microsoft.CodeDom.Providers.DotNetCompilerPlatform/
For example: 'Microsoft.CodeDom.Providers.DotNetCompilerPlatform -Version 3.6.0'
From 'cmd'(opened folder "dotnet-csharp-tools"), run command:
D:\dotnet-csharp-tools>nuget install Microsoft.CodeDom.Providers.DotNetCompilerPlatform -Version 3.6.0
From 'cmd' navigate to 'D:\dotnet-csharp-tools\Microsoft.CodeDom.Providers.DotNetCompilerPlatform.3.6.0\tools\Roslyn472'(warning : folder name 'Roslyn472' may be different, if is other version)
D:\dotnet-csharp-tools>cd Microsoft.CodeDom.Providers.DotNetCompilerPlatform.3.6.0\tools\Roslyn472
From 'File explorer' find 'csc.exe'(in the current folder 'Roslyn472').
Make copy of 'csc.exe' with name 'csc-roslyn.exe'(name can be whatever).
For 'Windows 10', open:
'Edit system environment variables' -> 'System variables' ->
'path' -> 'Edit' -> 'New' ->
D:\dotnet-csharp-tools\Microsoft.CodeDom.Providers.DotNetCompilerPlatform.3.6.0\tools\Roslyn472
Close and open again 'cmd'(the command prompt).
This 'cmd' restart needed, because 'system environment variables' are edited.
Check if 'csc-roslyn' is recognized by 'cmd' by run command:
csc-roslyn
Create folder 'D:\csharp-projects'(folder name can be whatever)
and create in 'D:\csharp-projects' C# source files, for example:
Vehicle.cs
class Vehicle
{
private string name = "unknown";
private int producedYear = -1;
public Vehicle(string name, int producedYear)
{
this.Name = name;
this.ProducedYear = producedYear;
}
public string Name
{
get { return this.name; }
set { this.name = value; }
}
public int ProducedYear
{
get { return this.producedYear; }
set { this.producedYear = value; }
}
}
Car.cs
class Car : Vehicle
{
private string maker = "unknown";
public Car(string name, int age, string maker)
: base(name, age)
{
this.Maker = maker;
}
public string Maker
{
get { return this.maker; }
set { this.maker = value; }
}
public override string ToString()
{
return $"{this.Name}, {this.ProducedYear}, {this.Maker}";
}
}
Autoservice.cs
using System;
class Autoservice
{
public static void Main()
{
Car car1 = new Car("Ford Taunus", 1971, "Ford");
Car car2 = new Car("Opel Ascona", 1978, "Opel");
Car car3 = new Car("Saab 900", 1984, "Saab");
Console.WriteLine(car1);
Console.WriteLine(car2);
Console.WriteLine(car3);
}
}
Open 'D:\csharp-projects' from 'cmd'(the command prompt) and run command:
csc-roslyn /target:exe /out:Autoservice.exe Vehicle.cs Car.cs Autoservice.cs
Run from 'cmd':
Autoservice.exe
Result should be:
Ford Taunus, 1971, Ford
Opel Ascona, 1978, Opel
Saab 900, 1984, Saab
