Example code for .NET Core

idata — Mon, 08 Oct 2018 14:57:05 GMT

I've been searching high and low for example code using .NET Core but haven't been able to find anything, is there anyone that have an example to share or could point me in the right direction?

Whilst there are no examples specifically for .NET Core, the RealSense SDK 2.0 does have .NET Framework compatibility in the 'csharp' category of wrapper. The main page for this wrapper has a C# example program, and links to several tutorial programs.

I believe that this is the first question that has been asked on this forum about .NET Core, so I'll post Microsoft's definition here for the benefit of other readers. .NET Core is "a cross-platform version of .NET for building websites, services, and console apps", whilst .NET Framework is "a Windows-only version of .NET for building any type of app that runs on Windows".

I do have have semi working code for the .NET core but have run into issues trying to use a PointCloud. I'm getting a nasty missing DLL exception using the Points.CopyTo and was looking to find out if any one else had run into the same problem and perhaps how to solve it. The exception only occurs on my linuxplatform (Ubuntu 16.04), on windows it works as intended.

The best place to seek an answer to this question is likely to be on the RealSense GitHub site, where the RealSense engineers and developers reside. You can post your question there by going to the link below and clicking the 'New Issue' button.
