 These demos have a relative path reference to VideoGrabberNET.dll declared here in the .csproj:

 <Reference Include="VideoGrabberNET">
   <HintPath>..\..\..\..\DLL\NET_Framework_4.8\VideoGrabberNET.dll</HintPath>
 </Reference>

 If compiling raises an error:

 - either edit the .csproj and specify the full path to VideoGrabberNET.dll
 - either open the demo project, go to "References":
   . remove the VideoGrabberNET.dll reference in error, 
   . add a new reference, 
   .  browse and select the location of VideoGrabberNET.dll.
   
 If this does not help please send an email to support@datastead.com 
 and let us know the error reported and the version of Visual Studio used.
