They are required updates to use .NET Core 3.1 Preview 3. Visual Studio 16.4 includes .NET Core 3.1, so just updating Visual Studio to 16.4 Preview 5 will give you the latest version of both products.<\/p>\n<p>Details:<\/p>\n<ul>\n<li><a href=\"https:\/\/github.com\/dotnet\/core\/tree\/master\/release-notes\/3.1\">.NET Core 3.1 release notes<\/a><\/li>\n<li><a href=\"https:\/\/github.com\/dotnet\/core\/releases\/tag\/v3.1.0-preview3\">GitHub release<\/a><\/li>\n<li><a href=\"https:\/\/github.com\/dotnet\/core\/issues\/3809\">GitHub issue for Preview 3<\/a><\/li>\n<\/ul>\n<h2>Go Live<\/h2>\n<p>This release is supported in production and you can call Microsoft support with issues.<\/p>\n<p>The <a href=\"https:\/\/dotnet.microsoft.com\/\">dotnet.microsoft.com<\/a> site (see version in footer) has been running .NET Core 3.1 in production since Preview 1 without issue and will be updated to Preview 3 shortly. We are confident about the quality of the release.<\/p>\n<h2>Closing<\/h2>\n<p>The primary goal of .NET Core 3.1 is to polish the features and scenarios we delivered in .NET Core 3.0. .NET Core 3.1 will be a <a href=\"https:\/\/dotnet.microsoft.com\/platform\/support\/policy\/dotnet-core\">long term support (LTS)<\/a> release, supported for at least 3 years.<\/p>\n<p>The initial download numbers for .NET Core 3.0 are even higher than we expected. We guess that 80-90% (or even higher) of the .NET Core ecosystem will move to .NET Core 3.1 within the first 6 months of the release. We are encouraging everyone to move to the 3.1 release as soon as they can, given that it has a lot of improvements (largely via 3.0) and is the newest LTS release.<\/p>\n<p>Please install and test .NET Core 3.1 Preview 3 and give us feedback.<\/p>\n<p>If you missed it, check out the <a href=\"https:\/\/devblogs.microsoft.com\/dotnet\/announcing-net-core-3-0\/\">.NET Core 3.0 announcement<\/a> from earlier this year.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Today, we&#8217;re announcing .NET Core 3.1 Preview 3. .NET Core 3.1 is a small and short release focused on key improvements in Blazor and Windows desktop, the two big additions in .NET Core 3.0..
