For developers working on .NET Core and other development servers, encountering port conflicts can be a common issue. Recently, I came accross with the default port (5000) used for local development server and the Intel(R) Graphics Command Center server.

Understanding the Issue: The Intel(R) Graphics Command Center server, specifically the OneApp.IGCC.WinService.exe executable, by default, utilizes port 5000. However, this port is commonly used for development servers in the .NET Core ecosystem and other software development environments. When both the Intel(R) Graphics Command Center server and a development server attempt to bind to port 5000 simultaneously, a conflict arises. ...
