I tried time stretching a wave file using .net unsuccessful. I am a new bee and I just need very brief if possible very easy way to accomplish that. There was one but it contains several other things which I do not really need.

If you expect that the stretched (I assume you mean play it in a shorter or longer time) wav does sound similar to the original (e.g. sound), than there is no easy solution in my opinion.

Why? OP did not pose any requirements on how it should sound. (And to sound exactly the same for different amount of time would be theoretically impossible; isn't that obvious?) The problem is quite solvable, why not?

Not enough information to help you. "Unsuccessful" is not an explanation of the problem. You need to show your code, explain the problem...

IMHO: Thatswhy I wrote "sound similar". There are a lot of softwares _trying_ it. E.g. the one I know are for musicians to play a piece of music in (slightly) different pitches.

Stretching without any assumption to quality is easy...but probably the result is not satisfying.

The key in "trying it" is in "it". What "it"? I think I know what do you mean, but as you formulate it, it sounds absurd. Different "pitches" is not just pitches; this is really complex non-linear transform. I see no sign of this stuff on OP's question.
