When developing debugging, the running ASPX page has the following problems:
asp.net Development Server failed to start listening on port 2083.
Error message:
Typically, each socket address (Protocol/network address/port) is allowed to be used only once.
After the study found that the original:
All unmanaged resource programs must be able to control the release of resources, such as database connections, socket connections, etc. should be displayed after use, if it is a long connection, you should ensure that all the connections that are occupied are closed when the program exits.
The bound port is not freed, it will need to wait for a while, or call close to shut down the UDP socket when the program exits.
I looked at the task manager process and found the last page of the development server that caused me to end the process:
Then run again, everything OK.
