Expected Behavior

Current Behavior

Trying to load a QR code into a window in my WPF App. It works when in Visual Studio when I use start or start without debugging. Then I encounter an error when I run the .exe file in the release or debug folders. Error is "Could not load file or assembly "QRCoder, Version = 1.6.0.0, culture = neutral, publickeytoken = c4ed5b9ae8358a28 or one of its dependencies. The system cannot find the file specified"

Check the bin folder: Navigate to your project's bin\Debug (or bin\Release) folder after building. Is QRCoder.dll present there? If not, this is the core issue.

Ensure Copy Local is True (if manually referenced): If you added QRCoder as a direct DLL reference (not via NuGet), right-click the QRCoder reference in your project's "References" (or "Dependencies"), go to Properties (F4), and ensure "Copy Local" is set to True.

Verify NuGet Package: If you're using NuGet (which is highly recommended for QRCoder), ensure the QRCoder package is correctly installed in your project. Sometimes, a project might have a reference, but the actual package files are missing or corrupted.

Reinstalling the package can help: Right-click your project -> "Manage NuGet Packages..." -> "Installed" tab. Find QRCoder. If it's there, try clicking "Uninstall" and then reinstalling it from the "Browse" tab.
