unknown6656-logo-1024.png missing. has invalid path.

wpfpslib.csproj has a link to "C:\Users\unknown6656\Pictures\unknown6656\unknown6656-logo-1024.png". This logo file doesn't seem to exist any where in the repo.

that is true :/
You can either remove the line from the csproj file or provide your own png as a logo and change the file path.
