The ASP.NET Core tag helpers improve on the HTML templated helpers in ASP.NET MVC 5. ASP.NET Core comes with some useful stock tag helpers for common tasks such as creating custom elements or extending existing HTML elements, but their use can be extended to making a framework such as Bootstrap easier to work with. Dino shows how helpers are used, and demonstrates a Bootstrap Modal Tag Helper

Microsoft Security Advisory for .NET Core Denial Of Service Vulnerability

CVE-2018-0765

Microsoft is releasing this security advisory to provide information about a vulnerability in .NET Core and .NET native version 2.0. This advisory also provides guidance on what developers can do to update their applications to remove this vulnerability.

Microsoft is aware of a denial of service vulnerability that exists when .NET Framework and .NET Core improperly process XML documents. An attacker who successfully exploited this vulnerability could cause a denial of service against a .NET Framework, .NET Core, or .NET native application.

The update addresses the vulnerability by correcting how .NET Framework, .NET Core, and .NET native applications handle XML document processing.

If your application is an ASP.NET Core application, developers are also advised to update to ASP.NET Core 2.0.8. 

Design patterns are solutions to recurring problems; guidelines on how to tackle certain problems I have included implementations of some design patterns in C# to help beginners like me get their feet wet.
