Which Visual Studio version is required to compile the Visual Studio samples?

All of our products, the SMS Component, E-mail Component as well as the SMS Server include a large number of sample applications. Most of which use Visual Studio.

The samples in C#, VB.NET and C++ use Visual Studio 2019.

All .NET samples use .NET framework 4.5.

The VB6 samples are the only exception in that they do use Visual Studio but always version 6.
