ASP.Net

History

• 2002: .net 1.0 webforms. ASPX pages with controls (absolutely positioned in this first version)
• 2005: .net 2.0 webforms. Master pages, GridView, themes. The first usable version.
  There was a large amount of cruft added. Asp Ajax (2007) had UpdatePanels, which were sorta ok before jquery. Some real ugly stuff like SqlDataSource, Dynamic Data
• 2009: MVC 1, but the first usable MVC, with Razor views, was MVC3 (2011). MVC 5 arrived in 2013.
• 2012: WebApi 1 broke from the old WCF RESTful services (ugh). It got usable with WebApi 2 in 2013, which was OWIN based (and a different pipeline to MVC 5) and had Cors, IHttpActionResult and attribute routing.
• 2016: .net Core with Asp Core 1 (previously known as MVC 6). Middleware-based (similar to OWIN), MVC/Razor and WebApi integrated, and cross platform. There are some missing pieces: back-compatibility (esp. in netstandard 1), and corporate bits like WsFed support for ADFS. These are mostly in place by Core 3.0/3.1
• 2021: .net 4.8 is the last framework version, .net 6 is the Core version.

Nuget vs jQuery

jQuery v2+ (2013) is not compatible with IE 6-8. Most corporate environments should be on Windows 7 with IE11 (2013), but WinXP users are stuck on IE8. In packages.config you can limit jQuery to the last IE8 comaptible version.
