I want to open a cash drawer in WPF using the .NET 7 framework. Firstly, I created the class library in.Net 4.5, and that reference was used in another class library from the same solution.
Note: Point of service is working fine only in .net framework 4.5, but I need to use it in my project, which is being used in .net framework 7.0.

It is not possible to refer to each other between .Net and .NET Framework projects. Only between .net and .net or between .NET Framework and .NET Framework projects can be used for mutual reference. Which CrashDrawer are you using? PosExplorer Class is a branch of the .NET Framework. You could try to re-create your CashDrawer library and change the target framework to .NET Standard or an appropriate .NET 5+ version.

2023-09-04T09:03:21.51+00:00 @Hui Liu-MSFT I have tried with .NET Framework 7.0 but I am unable to create instance of PosExplorer that's why I am using CashDrawer library with .Net 4.5. If you any idea about how to use PosExplorer class of PointOfService in .NET framework 7.0 please give me solution.
I am using the OPOS driver for cash drawer with RJ11 cable.
Wintec cash drawer

2023-09-04T09:39:50.7133333+00:00 Hi,@Jenish Patel. Based on my research, the
PosExplorerclass should not be available in .NET 7.0. ThePosExplorerclass was part of the .NET Framework's PointOfService namespace. It seems there was no direct equivalent or replacement for the PosExplorer class in the .NET 7 framework, or any previous versions of .NET Core.However, .NET Core and later .NET versions took a different approach to device access, and POS device management was not included in the standard libraries. Instead, developers were encouraged to use platform-specific libraries or third-party libraries for POS device integration.
