Correct return type for validation errors

I need to implement validation in my web api controller. In my class I have a method like this:

public MyEntity Post(MyEntity entity)
{
   // ...
}

In POST and PUT methods I usually return the created/updated object.

In this tutoral they are returning a HttpResponseMessage so that they can do something like this:

if (ModelState.IsValid)
{
    // Do something with the product (not shown).

    return new HttpResponseMessage(HttpStatusCode.OK);
}
else
{
    return Request.CreateErrorResponse(HttpStatusCode.BadRequest, ModelState);
}

Is there a way to use a similar approach returning the saved entity?

You should use HttpRequestMessageExtensions.CreateResponse method. For example:

if (ModelState.IsValid)
{
    // Do something with the product (not shown).

    return Request.CreateResponse<MyEntity>(HttpStatusCode.OK, entity);
}
