JetBrains has produced the first Release Candidate (2017.1) of Rider, their .NET-focused multiplatform IDE. Rider's 2017.1 latest features focus on performance, WebStorm functionality, private authentication for Nuget feeds, and of course more bug fixes.
Windows users should see a faster Rider startup fime as JetBrains has shaved approximately 5-10 seconds off the previous time. Editing F# code should also run faster as several editor freezes have been removed.
NuGet users should benefit from fixes in several areas. First, NuGet restore is only executed when needed, whereas previously it was called on every solution load. When restoring packages, the local cache is checked first. When a project toolset is changed, Rider will run NuGet restore to ensure the correct dependencies are present and referenced properly.
Another addition to NuGet support lies with the addition of credential support for users of private or in-house NuGet feeds. This means a NuGet feed that requires a username and password can be used with Rider as that information can be entered and stored within Rider's password store.
JetBrains states that for the best results, WebStorm should be used to edit common web file types like JavaScript, TypeScript, CSS and HTML. That said, Rider does have some inherited functionality from WebStorm to be make editing Web.config files user-friendly. This functionality extends to other .config files (e.g. App.config) and MSBuild files too.
When an application is launched from Rider, it is now possible to redirect console output to an external console rather than have it displayed from within the IDE. This is configurable and applies when the application is launched in the IDE's Run/Debug mode.
Rider RC1 is available for download on Mac, Windows, and Linux systems.
