Using Directory.Delete() and Directory.CreateDirectory() to overwrite a folder

Question

In my WebApi action method, I want to create/over-write a folder using this code:

string myDir = \"...\";
if(Directory.Exists(myDir)) 
{
    Dir

Sounds like race condition to me. Not sure why - you did not provide enough details - but what you can do is to wrap everything in lock() statement and see if the problem is gone. For sure this is not production-ready solution, it is only a quick way to check. If it's indeed a race condition - you need to rethink your approach of rewriting folders. May be create "GUID" folder and when done - update DB with the most recent GUID to point to the most recent folder?..
