MakeInterface

Creates an interface of a class using source generator

Add the attribute to the class you want to generate the interface for

[GenerateInterface]
public class MyClass
{
	public string MyProperty { get; set; }
	public void MyMethod() { }
}

The generated interface will then be generated as IMyClass.g.cs

public interface IMyClass
{
	string MyProperty { get; set; }
	void MyMethod();
}

You can then implement the interface in your class

public class MyClass : IMyClass
{
	public string MyProperty { get; set; }
	public void MyMethod() { }
}

Install the NuGet package MakeInterface

You can either create the attribute yourself or use the one provided in the package MakeInterface.Contracts
