How to automatically create (e.g. singleton with C # using CodeDOM / T4 / PostSharp / whatever?

I am looking for a way to automatically create (e.g.) singleton, for example:

[SingletonPatternAttribute]
public class Logger {
    public void Log (string txt) { /* do logging... */ }
}

as an attempt to eliminate the template.

Does anyone know how to do this? I know that there are CodeDOM, Reflection.Emit, T4and so on. Also - there is (most noticeably) PostSharp, but I would be very glad to see a real solution for the aforementioned task.

I can do code generation in the constructor, for example, but the compilation time is obviously much better.

Edit:

The problem here is not singleton, but in generator / meta programming in C#- how to create code / exclude the boiler stove in the best way - what specific examples are there?
