As of 2/1/2020,  we will start deprecating all .Net 4.5 (multi-file) SDKs.  Our Visual Studio SDK will be like our C SDK, which means no more individual device SDK, instead a single combined SDK with documentation of all the device API calls. We will offer builds compiled for .Net 6.5.1, .Net Standard 2.0, .Net Standard 2.1 and .NetCore 3.1, allowing it to work across multiple platforms. While all API functions/callbacks are the same as the deprecated .Net 4.5 version, internally there has been a complete re-write of all communication drivers (USB, IP, Serial).  This should provide a new level of robustness.
