Using Reverse Package Search in ASP.NET Core

Using Reverse Package Search in ASP.NET Core

ASP.NET 5 provides a much more granular way of specifying the dependencies your applications has. This is done in the project.json file, like so:

 "dependencies": {
    "Microsoft.AspNet.IISPlatformHandler": "1.0.0-*",
    "Microsoft.AspNet.Server.Kestrel": "1.0.0-*",
    "Microsoft.AspNet.Diagnostics": "1.0.0-*",
    "Microsoft.Framework.Logging.Console": "1.0.0-*"

But what happens if you can’t remember where some package is located? Maybe you’re building an ASP.NET 5 application and you want to add logging to it. You remember that Logging is located in the AspNet repository on GitHub, so naturally you figure it must be under “Microsoft.AspNet” – but it’s not! Where is it? How can you find it? Reverse Package Search can help.

Perform a search for logging, and you’ll quickly see all packages that include this string.

Note that this doesn’t just match on the package name – you could probably achieve that using the Nuget GUI tool in Visual Studio. Reverse Package Search will also let you search for something that exists within the package, such as a type name (example, ILoggerFactory). Often, you’re looking for a particular type, and don’t know which package it’s ended up in, so this can be quite useful.

Hope this helps!
