Microsoft on Tuesday released fixes for 58 newly discovered security flaws spanning as many as 11 products and services as part of its final Patch Tuesday of 2020, effectively bringing their CVE total to 1,250 for the year.
All of these tools are shipped as part of Visual Studio but are not installed in the same way as you would install them manually. They are all located in the Visual Studio install directory and are used by some of the new features such as the Task Runner Explorer and the new ASP.NET 5 project system.
In Visual Studio 2013, there were a handful of templates that supported developing ASP.NET projects with various frameworks and data structures. Some of those project templates from the Visual Studio 2012 era have been removed from the Visual Studio 2015 install and added to the Visual Studio Extension gallery as the ASP.NET Project Templates extension for Visual Studio 2015.
