Sample requires installation of .NET Framework devpack 4.6.1 (not supported) and throws exception on launch.

Visual Studio 2022 displays a modal when you first open the UserSync solution asking if you want to update the code to the latest framework or launch a browser to download the 4.6.1 framework. If you launch the browser, .NET Framework 4.6.1 does not show in the "supported" list. You can do it by changing the URL for 4.6.2, the supported version.

After installing 4.6.1 and relaunching Visual Studio, there is no modal.

After build and Run, I get the following exception immediately on launch:
"Could not load file or assembly 'Microsoft.Owin, Version=4.1.1.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)"

Open the UserSync solution in Visual Studio 2022 and reproduce the framework prompt, build, and launch failure. Inspect the solution's framework and Microsoft.Owin assembly references to identify the version mismatch. Done means the sample builds and launches without the unsupported framework prompt or the Microsoft.Owin exception.
