.NET Core 3.0 Hits Release Candidate Phase

Microsoft has announced the release of .NET Core 3.0 Release Candidate (RC1), a near-final version of its portable software platform. The software giant expects to deliver the final version of .NET Core 3 next week at its .NET Conf virtual event.

“We’ve focused on polishing .NET Core 3.0 for a final release,” Microsoft’s Richard Lander explains. “We are now getting very, very close.”

If you’ve been following .NET Core 3 development, you know that Microsoft didn’t originally plan to ship an RC version; instead, the earlier Preview 9 release was expected to be the last major milestone before the final version. But Microsoft added the RC1 release to sync up with Visual Studio 2019 16.3 Preview 4 and Visual Studio for Mac 8.3, both of which were just released as well.

“It is critical that the .NET Core SDK version that is part of any Visual Studio release includes the same toolset in order to deliver a compatible experience in all scenarios,” Lander noted, adding that the team should have seen this coming.

Regardless, .NET Core 3.0 RC1 is fully supported by Microsoft and can be used in production. Microsoft originally announced .NET Core 3.0 this past May at Build 2019, and the biggest change is support for Windows Presentation Foundation (WPF), Windows Forms, and Universal Windows Platform (UWP) applications on Windows. Microsoft also revealed at the time that its next release, .NET 5.0, will be based on .NET Core and will replace the legacy .NET platform. (This seems similar to when NT 5.0 “became” Windows and was renamed to Windows 2000.)

      <blockquote><em><a href="#466849">In reply to MartinusV2:</a></em></blockquote><p>I thought the WPF designer was included in the latest version… It was just the Winforms designer that was missing. </p>

      <blockquote><em><a href="#466849">In reply to MartinusV2:</a></em></blockquote><p>Designers for Windows Forms will be available later in .NET Core 3.1 at the final of this year. </p>

    <p>.NET Core 3.0 also includes the first official release of Blazor, a C#/.NET SPA framework that can run either client-side (through WebAssembly magic) or server-side (in a shadow DOM that syncs with the browser through SignalR). This hasn't really gained the attention it deserves: just imagine writing a fully dynamic web application without a single line of JavaScript…</p>

      <blockquote><em><a href="#467516">In reply to dontbeevil:</a></em></blockquote><p><br></p><p>UWP is Microsoft's current UI platform. MS wants WinForms and WPF to die instead. However, it looks the developers aren't ditching WinForms/WPF in favour of UWP. So MS has to keep supporting it. It is MS's fault for changing the UI platform so frequently and in a very backward-unfriendly way. I admit it's usually very annoying to use an UWP app on a desktop PC.</p>

          <blockquote><em><a href="#467631">In reply to saint4eva:</a></em></blockquote><p>The UWP story always reminds me of when .NET was introduced to replace COM. The VB6 fans (including myself) fought it hard. We are writing Enterprise LOBs with UWP now, for the Desktop. </p>

    <p>so looks like once again I was banned, as usual no notifications and no breaking rules:</p><p><br></p><p>I simply pointed out what's written in this article: "and the biggest change is support for Windows Presentation Foundation (WPF), Windows Forms, and Universal Windows Platform (UWP) applications on Windows"</p><p><br></p><p>but of course paul didn't appreciate it, as he's continuing for some reasons his personal war against UWP, at least on twitter there is enough people that start to understand this</p><p><br></p>

        <blockquote><em><a href="#469407">In reply to chocolate starfish:</a></em></blockquote><p>You and Paul should stop banning and deleting people's comments. It is very bad and not a good behaviour at all. People have their own opinions also</p>

    <p>What parts of UWP are being supported now anyway? I can't actually find any details about .Net Core 3 supporting any UWP/WinRT features beyond what was already available. And I thought better UWP support wasn't coming till next year.</p>
