by Bruce Arnold .

Csig1703

Welcome to the CSIG, a Special Interest Group of the ACGNJ. This is an exciting time for the C Language programming since Microsoft now has several different language compilers that include: C++, and C-Sharp. These are all capable of creating Windows (tm) programs. (Some are FREE!) During the meeting there will be time for Random Access Questions as well as other discussions.

Here's a brief synopsis of the coming meeting:

The Microsoft Web Site has a new section on Visual Studio 2017. WHAT'S NEW This was just released the 2nd week of March 2017. As in the past, I will be using the free version which in this case is called "Visual Studio Community 2017". Shown below is a view of the C# project creation screen for a Windows Forms user interface. Also, as in the past, Microsoft has left out the Windows Forms Template for C++. In the comming months we will discuss workarounds for this issue. During tonight's meeting, we will discuss some of the interesting items on the web site as well as show some of the Microsoft videos. This new development system also allows coding in Apple, Linux, and Android operating systems. And of course there will be time for Random Access and questions.

VS2017

There are a number of ways to refer to Microsoft's latest compilers and code. Here's what Wikipedia says: The Common Language Infrastructure (CLI) is an open specification developed by Microsoft that describes the executable code and runtime environment that form the core of the Microsoft .NET Framework. The specification defines an environment that allows multiple high-level languages to be used on different computer platforms without being rewritten for specific architectures.

Microsoft .Net Framework 4.5
