Last month Microsoft announced the release of TypeScript 0.9.5, which the company seems to feel is getting pretty close to a version 1.0 release, despite the inclusion of some breaking changes that's still happening with every release. The 0.9.5 release fixes several different bugs and memory issues, and incorporates feedback from the community that's quickly growing around TypeScript.
Despite the inclusion of TypeScript version 0.9.1.1 in a release candidate version of Visual Studio 2013, the final Visual Studio RTM version didn't include the latest version of TypeScript. If you read between the lines of various Microsoft TypeScript blog posts, they were clearly hoping to include version 1.0, but it just didn't happen.
In what's one of the odder ways that Microsoft has come up with to install a technology in Visual Studio, you can get the latest version of TypeScript by creating a new project and selecting the Install the Latest TypeScript for Visual Studio project template, as shown in Figure 1. With the availability of NuGet, Visual Studio extensions, and the Web Platform Installer in Visual Studio, it's a bit of a strange way to install TypeScript. One of these days I'll have to ask Someone Who Knows why they chose this route. Anyway, the template opens a web page that lets you download the latest version of TypeScript for Visual Studio 2012 and 2013, and then you'll need to run the installer to get the full benefit of TypeScript goodness. Just be aware that the installation will install TypeScript for both Visual Studio 2012 and 2013 if they are both installed on your machine.
As you can see in Figure 1, you also have a project template that makes it easy to create an HTML page that uses TypeScript. Although there's nothing too fancy in the project template, it's a handy way to get a feel for using and playing with some of TypeScript's features, as it creates a .ts TypeScript file with some simple code that sets up a timer to continuously display the current time on an HTML page.
As of a couple of months ago, the company was expecting that with the 0.9.5 release it would have the version 1.0 specification completed. I've not been able to find such a spec on the web yet; the link to the spec on the main TypeScript homepage is still version 0.9.5, dated 18 November 2013. The specification is fairly interesting to scan, providing a lot of good background about the language features, generally written in readable English, unlike so many jargon-dense web specifications.
