We plan to migrate the project to .NET Core cli in the future, but we are waiting for at least the first official "tooling" release of .net core cli. The tooling release is the first release that includes visual studio integration.
You will also need to install the current version of .net core cli. You can find instructions here: https://dotnet.github.io/
Once .Net core is installed and working, follow these instructions:
Launch the software and enable the socket server.
Open a terminal and cd to the freshly extracted coreSaleaeAPI directory.
Run "dotnet restore".
Run "dotnet run".
The sample app will automatically connect to the software and start a capture. Once the capture is finished, the console app will say "Done!" and you can press any key to exit.
That's it! This is a very rough port, and a few changes need to be made off the official GitHub project. Once we are able, we will port the official GitHub project so it can run using both .NET core and the standard .NET framework.
Note: This has only been tested on Windows and Ubuntu 14.04. If you have any problems, please contact Saleae support.
