I use the Syncfusion Essential Wpf library for a PDF utility program. I found some issues in the PDFViewer and Syncfusion acknowledges and fixed those and eventually advised to install the weekly updates via NuGet. I was reluctant to do so because NuGet often meant trouble in the past, and this time again. The installation worked fine but I now had to add a license key in my code (which was not necessary for the regular installations from an exe) and that didn't work. Instead of finding out why, I decided for now to wait for a regular update and remove the NuGet installations via the Package manager in the VS Tools menu which worked. I removed the references and assigned the previous DLL's. But now my program wouldn't start; only in debugging mode I saw the message was Can't load Syncfusion.Shared.Wpf version 23.1460.42.0, which was the version supposed to be removed. But why?
I suspected the GAC (Storing something in the GAC cause comparable trouble as using NuGet) and de-installed syncfusionessentialwpf.exe, checked to remove GAC settings, reinstalled without copying anything into the GAC, copied all the DLL's I used, deleted and recreated the reference. However the problem remained.
Overnight Syncfusion support handed me the solution. In the App.config, I found these lines as they suspected:
This was still pointing to the "42.0" removed version and apparently caused the problem. Removing this section solved my problem.
