After leaving Visual Studio one night in debug mode stopped on one line, I could no longer run the web application locally because of an error in IIS Express .
I tried to stop IIS Express and reopen Visual Studio, but it did not work.
As this post of a blog:
The code error
0x80070020meansERROR_SHARING_VIOLATION, which in the case ofIIS Express(orIIS) means that the port thatIISis trying to listen to is being used by another process. >
To find out which application is using the port, just run the command netstat on cmd with the following syntax: netstat -ao | findstr número_da_porta_que_está_pesquisando
The
aparameter is responsible for displaying all connections and ports heard. Theoparameter is responsible for displaying the process ID associated with the connection.
Running the above command:
C:\Users\Daniel>netstat -ao | findstr 49286
TCP [::1]:49286 Daniel:49286 ESTABLISHED 4280
After finding the process ID, which is displayed in the last column of the command return, just search its name using tasklist :
C:\Users\Daniel>tasklist /FI "PID eq 4280"
Image Name PID Session Name Session# Mem Usage
========================= ======== ================ =========== ============
firefox.exe 4280 Console 1 601.012 K
Or you can join kill process with taskkill :
C:\Users\Daniel>taskkill /PID 4280
