This article explains what is needed to work with ETS6 SDK.
.NET Framework
The .NET Framework 4.8 (or higher) must be installed. This might come along with the setup of the development environment. See Development environment section if this step can be skipped.
Development environment
A development environment that supports development of .NET Framework 4.8 (or higher) DLLs is required. The ETS SDK is compiled against .NET Framework 4.8, so the development environment must at least support this version (e.g. Microsoft Visual Studio 2019 or later).
ETS
Especially for app development, it is recommended to install the latest ETS version. The required DLLs are installed via the ETS setup into the ETS installation directory. We ensure the compatibility of these DLLs with future versions.
SDK
The ETS SDK is distributed as nuget package. You may install this package either on a private company nuget server, or simply on a local directory or network share (see nuget local feeds). Add this nuget package as reference to the C# project.
