Daniel, I trayed to clone and built DWSIM app, however I was getting a lot of errors when "build" the solution. Please find a screenshot attached. Seems like something is happening with DWSIM.Thermodynamics specifically with Eto.Forms.Controls.Scintilla just to mention one. Please let me know if I am doing something wrong. I want to take the opportunity to say thank you for your endless effort making this software open source. Regards, Andres Abril
