litedb setup failed
Setup failed: The process cannot access the file 'C:\grandnode2-main\src\Web\Grand.Web\App_Data\database.db' because it is being used by another process.
@Taraweesh, just kill your visual studio and try again also ensure you don't have the app terminal running for GrandNode. Check for Multiple Application Instances of GrandNode. The file may have been locked by filesystem or some vs process. As last resort, Restarting the machine should resolve the issue.
Another approach if you like find the process using the file and kill the process.
Assuming, you are on windows. Use tools like Handle or Process Explorer from Sysinternals to identify which process is locking the file: Download and open Process Explorer. Press Ctrl+F and search for database.db. It will show the process locking the file. You can end the process from there.
