Deleting folder no longer causes asp.net application to restart in asp.net 4 -

in asp.net 2, deleting folder cause application restart. today found behavior no longer existed in asp.net 4? can't find info this. can tell me if true? if yes, that's awesome! hate application restart behavior in asp.net 2. can seek this:

debug next code in asp.net webforms (.net 3.5) , you'll grab threadabortexception. when debug in asp.net webforms (.net 4), won't grab exception; fine. think reason why got threadabortexception deleted directory in thread. application restarted, , thread got aborted. (environment: win8, vs2012, iis express)

protected void page_load(object sender, eventargs e) { var thread = new thread(() => { var folderpath = path.combine(appdomain.currentdomain.basedirectory, "app_data\\test"); var filepath = path.combine(folderpath, "test.txt"); if (directory.exists(folderpath)) { directory.delete(folderpath, true); } directory.createdirectory(folderpath); system.io.file.writealltext(filepath, "hello"); seek { var loop = 100; while (loop > 0) { thread.sleep(100); loop++; } } grab (exception ex) { var msg = ex.message; } }); thread.start(); response.write("running"); }

as fas i can see there not difference between 3.0 , 4.0, next action cause app restart:
