The CVB.Net API is an object oriented wrapper for the CVB SDK. It has been designed to harmoniously integrate into the .Net API and makes leveraging the abilities of CVB for complex applications written in one of the .Net/CLR languages easier than the classic C-like API. CVB.Net has been built versus the .Net 4.7.1 runtime and therefore requires Visual Studio 2015 or higher to work with. On platforms other than Windows, the CVB.Net API can be used with .NET Core 3 and above - provided that no Windows-specific elements have been used (like e. g. the registry or elements from WPF).

For GUI integration, Cvb.Net offers WPF integration:

• WPF applications can use the Stemmer.Cvb.Wpf.dll which provides an implementation of a Display written as a native WPF component. That way it gives access to all visual elements and capabilities of WPF. As it has been designed as a Canvas all sort of WPF UI elements can be used with it.

Recommendation: While in principle all Cvb.Net DLLs have been implemented as IL DLLs, the fact that there is currently no hybrid CVB installer (i.e. an installer that simultaneously installs the 32 and the 64 bit build on a 64 bit operating system) makes it necessary to stick with the architecture that has been installed on your system.
This specifically means that with a 64 bit installation one cannot expect an x86 build to run and vice versa and that Any CPU builds should not be used when working with a 32 bit installation on a 64 bit operating system (It is, however, possible to build an AnyCPU IL *.exe and then deploy it to either a 64 bit OS with the 64 bit build installed or a 32 bit OS with the 32 bit build installed).

A good resource to actually get started with CVB.Net is the Getting Started with CVB.Net guide in the CVB forum.
