1.    Finally, we will change the code to update the webpart output, without re-deploying.

2.    Go back into your code and change the output line; for example, what is listed below.

Listing 4

writer.Write(@"Hi there, " + this.Context.User.Identity.Name + 
    @" (this output has been changed and recompiled.)");

3.    Press <Control><Shift><B> to rebuild your assembly.

4.    Go back to your web page and press refresh.

5.    Without having to re-deploy, your Web Part's output has been updated.

6.    This now becomes a fast way to iterate through the process of building, deploying, testing, updating and testing again your code.
