run single *.cs script from command line

Question

Is there at last a easy way to execute c# script file from command line?

I saw that discussion on github

and according to this thread i think dotnet run Test.cs should do the job.

But for my testclass which is:

using System; namespace Scripts {     public class Program     {         public static void Main(string[] args)         {             Console.Out.WriteLine("This is the miracle");         }     } } 

it fails

PM> dotnet run .\Test.cs  dotnet.exe : Object reference not set to an instance of an object.At line:1 char:1 

So how could I execute the code in single file using command line in relatively easy manner?

UPD 1: As correctly mentioned by @Lee and @svick dotnet run is for running project. But my initial question was - how to run single file. Maybe some options using roslyn?

I found another solution on Scott Hanselman's blog:

https://www.hanselman.com/blog/CAndNETCoreScriptingWithTheDotnetscriptGlobalTool.aspx

It relies on a .NET CLI tool called dotnet-script, you can find its repository below:

https://github.com/filipw/dotnet-script

To use, it, first install it using dotnet tool install -g dotnet-script

Then you can run dotnet script and use it as a REPL or run dotnet script file.csx to run a file.

To include a NuGet package reference, use #r "nuget: AutoMapper, 6.1.0".
