Hello, AbdelrahmanMostaf.
Make sure the files (Saraff.Twain.WebSample.dll, Saraff.Twain.dll and Saraff.Tiff.dll) can be obtained by GET request. Make sure that the version of the Saraff.Twain.dll and Saraff.Tiff.dll assemblies match those specified in the Saraff.Twain.WebSample.dll assembly.

Hello, Manooo.
Source files (or binary files) should be taken from sites related projects (Saraff.Tiff.NET, Saraff.AxHost.NET, Saraff.Twain.NET). It is necessary to use the latest versions of files.
It is assumed that you are familiar with the TWAIN, as well as possess the skills development of web applications.
You can review the documentation of Saraff.Twain.NET.
An Saraff.Twain.WebSamples can only run in IE, because it is based on ActiveX.
