When i call method then first time write data on port but second time get error:-Access to the port 'COM1' is denied. When I comment this line. Communication between Windows service and WCF service. UMDF comport driver problem. Hello Experts, I'm a newbie with WCF Service in.NET, but want to implement a Business requirement.Currently, we have a Windows Desktop Application written in C#2.0, which deals with Read/Write data over Serial Port from a device.
Usually, the factory of barcode scanner would provide the API for developers, you could develop your application by referring the API document.
