RSCG_Static

Roslyn Source Code Generator - transform static classes into instances and interfaces

More, there is a MakeNew static method created to can have DI.

Just put a function like this ( example for System.DateTime)

        public Type GenerateInterfaceFromDate()=>typeof(DateTime);

and the properties of the classes will be generated into interfaces and you can write:

//for DI, register
//ISystem_DateTime  with transient for new clsSystem_DateTime()
Console.WriteLine("Hello World!");
ISystem_DateTime dateStatic = recSystem_DateTime.MakeNew();//static
ISystem_DateTime dateVar = new clsSystem_DateTime(); //variable = real 

Console.WriteLine(dateStatic.Now.Second);
Console.WriteLine(dateVar.Now.Second);
await Task.Delay(10 * 1000);
Console.WriteLine(dateStatic.Now.Second);
Console.WriteLine(dateVar.Now.Second);
