Incorrect registry path of StylusLogic

[LickBag]

Description

In the file StylusLogic.cs , Line 74 :
private const string WispRootKey = @"Software\Microsoft\Wisp\";

In the file StylusLogic.cs , Line 79 :
private const string WispPenSystemEventParametersKey = WispRootKey + @"Software\Microsoft\Wisp\Pen\SysEventParameters";

Then, the WispPenSystemEventParametersKey value actually is @"Software\Microsoft\Wisp\Software\Microsoft\Wisp\Pen\SysEventParameters";
Maybe the path is wrong, I think the correct WispPenSystemEventParametersKey value should be WispRootKey + @"Pen\SysEventParameters"
You can open the Registry Editor to verify it

Can you please help us understand which scenario is currently breaking because of the above ?

@LickBag Good catch. Thank you. It must be Pen\SysEventParameters.

wpf/src/Microsoft.DotNet.Wpf/src/PresentationCore/System/Windows/Input/Stylus/Common/StylusLogic.cs

Lines 66 to 84 in 42f7d5d

	/// <summary>
	/// The key to assert access to for WISP data
	/// </summary>
	private const string WispKeyAssert = @"HKEY_CURRENT_USER\" + WispRootKey;
	/// <summary>
	/// The root of all WISP registry entries
	/// </summary>
	private const string WispRootKey = @"Software\Microsoft\Wisp\";
	/// <summary>
	/// The event parameters for WISP pen input
	/// </summary>
	private const string WispPenSystemEventParametersKey = WispRootKey + @"Software\Microsoft\Wisp\Pen\SysEventParameters";
	/// <summary>
	/// The WISP touch paramaters
	/// </summary>
	private const string WispTouchConfigKey = WispRootKey + @"Software\Microsoft\Wisp\Touch";

The code remains unchanged from its first open source status: #720

Update:

I can sure that this issues is brought by .NET Framework. I use ILSpy to view the C:\Windows\Microsoft.NET\Framework\v4.0.30319\WPF\PresentationCore.dll file. And I can find the wrong path:

@pranav-gupta-msft I think @LickBag has expressed the problem very clearly. As you can see:

wpf/src/Microsoft.DotNet.Wpf/src/PresentationCore/System/Windows/Input/Stylus/Common/StylusLogic.cs

Lines 66 to 84 in 42f7d5d

	/// <summary>
	/// The key to assert access to for WISP data
	/// </summary>
	private const string WispKeyAssert = @"HKEY_CURRENT_USER\" + WispRootKey;
	/// <summary>
	/// The root of all WISP registry entries
	/// </summary>
	private const string WispRootKey = @"Software\Microsoft\Wisp\";
	/// <summary>
	/// The event parameters for WISP pen input
	/// </summary>
	private const string WispPenSystemEventParametersKey = WispRootKey + @"Software\Microsoft\Wisp\Pen\SysEventParameters";
	/// <summary>
	/// The WISP touch paramaters
	/// </summary>
	private const string WispTouchConfigKey = WispRootKey + @"Software\Microsoft\Wisp\Touch";

The private const string WispPenSystemEventParametersKey = WispRootKey + @"Software\Microsoft\Wisp\Pen\SysEventParameters"; will be :

Software\Microsoft\Wisp\Software\Microsoft\Wisp\Pen\SysEventParameters

There are some keys (Software\Microsoft\Wisp) that are repeated.
