If you can't read my code, try converting it here[^]

foreach (var element in checkedListBoxServices.CheckedItems)
{
    textBox1.Text += ((string)element) + Environment.NewLine;
}

During compilation? Sounds like you added the same class more than once, and that would confuse the compiler. Try renaming your class; if it works after that, you've got a copy of the class "somewhere" in your code.

When you mention "WSBackDataFrameofClass_1" in code, how would the compiler know which of those two classes you meant? Put them in a separate namespace to make them unique, or change on of the names.

The reference file created by WBServices export this definition of those classes but in a prevoius prj that are not wcf(and it work!!!!).

May be we can't expect this in the right order? as they are "Threads!"?

for (int i = 0; i < 4; i++)

    Thread t = new Thread(() => simpleThread(i));

Thread t = new Thread(() => {
