  About Us
The C#/VB.Net SIG (Special Interest Group) is a non-profit, volunteer based organization aimed at helping all levels of computer users, ranging from hobbyists to consultants. The objective of the SIG is to provide a forum for sharing information and networking with those who work with C# and Visual Basic.Net. We invite programming professionals, as well as hobbyists, to join us every month.

Aside from the monthly meetings, we also communicate regularly via e-mail getting input on how to resolve various coding problems. The meetings are a great place to network and meet with others in the software industry.  The group meets once a month, typically every 4th Monday, to discuss various topics related to C# and VB.Net.  Meetings are free of charge and open to the public. 

Our group is affiliated with the GCPCUG (Greater Cleveland PC Users' Group), a non-profit, volunteer based organization with the purpose of serving as an acknowledged source of computer technology information.  We are also a member of INETA (International .NET Association), a non-profit, independent organization, chartered with supporting all user groups interested in the Microsoft .Net platform.   In addition, the Cleveland C#/VB.Net Special Interest Group is affiliated with the Microsoft's Mindshare (MSDN User Group Network).

Topic: "Custom Middleware with OWIN and Katana in ASP.NET vNext" By Ondrej Balas

Date: Monday, June 22, 2015, 6:30 PM - 8:30 PM

Description: OWIN and Katana are at the core of ASP.NET vNext, giving developers full control over the ASP.NET pipeline. In this session I will explain exactly what OWIN and Katana are and how they empower you to quickly and easily reconfigure an entire web application. Now in full control, you can do everything from injecting custom code (middleware) right into your pipeline to running your web applications without IIS.
