NuGet 3 Nearing Completion

CTP 1 of the Microsoft development platform package manager introduces a new package source, speeds up performance and adds a debugger console.

Microsoft is nearing general availability of its NuGet 3.0, a package manager for its development platform tools that's part of the Visual Studio Extensions Gallery. Before that happens, the company is offering the first of a series of community technology previews (CTPs). This first CTP release introduces a new package source and speeds up performance. It also introduces a new debugger console.

The new package source is called "nuget.org (3.0.0-ctp1) preview," and, according to the blog post announcing the CTP 1, performance has been sped up a bit. The speed improvement is attributed in part to client requests being directed to Microsoft's content delivery network (CDN) to get data from storage, therefore bypassing the "v2 OData v2 endpoint on the server."

The blog also said some "under the hood changes" had to be made in order for development to progress on version 3. One such change was "drastic refactoring of the dependency resolver" to get it to resolve dependencies independent of the packaging process. The other was the interception and translation of API v2 requests (via a JSON intercept resource) to API v3 requests when a server implements API v3. The problem being solved here is that in the absence of an API v3 client (still under development), any request ends up appearing as if it were API v3 request, so "every single request the client makes ends up going against our API v3 Search Service and JSON-LD resources."

The other change is a new Package Manager Debug Console, included in the Visual Studio extension. As noted in the blog, Microsoft used the console to peer into the inner workings of the API v2-to-API v3 intercept process and its results.

Note that this version will work with Visual Studio versions 2013 and Visual Studio "14" only, for now: "We have always had a single extension that targets both of those versions, whereas we have a separate extension for Visual Studio 2013 and Visual Studio "14." NuGet 3.0 is now using some libraries that require .NET 4.5, and that would rule out updates for Visual Studio 2010."

NuGet 3.0 CTP 1 for Visual Studio 2013 can be downloaded here; for Visual Studio 14, it's here. Upon general availability in September, NuGet 3.0 will be available via the Visual Studio Extensions Gallery.
