Last .NET Core 3.0 Preview Ships 3 Weeks Ahead of Final Release

Microsoft has shipped its last preview of the long-awaited .NET Core 3.0, which will launch in GA later this month during the Sept. 23-25 .NET Conf online event.

.NET Core 3.0 will mark a major milestone in the .NET journey as the company moves off the old, proprietary Windows-only .NET Framework to an open source, cross-platform future.

Today, the company unveiled .NET Core 3.0 Preview 9, described as "less exciting" than previous builds as the dev team focuses on polishing existing features and functionality rather than introducing new stuff.

.NET Core 3.0 code has already been declared production-ready (having powered the Microsoft .NET site for many weeks) and has worked successfully with Visual Studio 2019 16.2, but the Redmond software giant is advising developers to use it with Visual Studio 2019 16.3.

"We know that some folks have been successful using .NET Core 3.0 builds with Visual Studio 2019 16.2 and wonder why 16.3 is required," the company said in a blog post today (Sept. 4). "The short answer is that we only test .NET Core 3.0 with Visual Studio 2019 16.3 and have made many improvements and key fixes that are only in 16.3. The same model applies to Visual Studio for Mac 8.3."

The free .NET Conf virtual event during which .NET Core 3.0 will officially be launched will feature shorter 30-minute sessions this year but will cover twice the number of topics as in previous years.

Microsoft also today released new versions of .NET Core's ASP.NET Core 3.0 component, EF Core and Visual Studio 16.3 Preview 3.

.NET Core 3.0 Preview 9, running on Windows, macOS and Linux, can be downloaded here. The skimpy release notes can be seen here.
