.NET 5 Preview 5 is now available and is ready for evaluation! .NET 5 will be a current release.

Get started

To get started with ASP.NET Core in .NET 5.0 Preview5 install the .NET 5.0 SDK.

If you’re on Windows using Visual Studio, we recommend installing Visual Studio 2019 16.6.

If you’re on macOS, we recommend installing the latest preview of Visual Studio 2019 for Mac 8.7.

Upgrade an existing project

To upgrade an existing ASP.NET Core 5.0 preview4 app to ASP.NET Core 5.0 preview5:

  • Update all Microsoft.AspNetCore.* package references to 5.0.0-preview.5.*.
  • Update all Microsoft.Extensions.* package references to 5.0.0-preview.5.*.

See the full list of breaking changes in ASP.NET Core 5.0.

That’s it! You should now be all set to use .NET 5 Preview 5.

What’s new?

Reloadable endpoints via configuration for Kestrel

Kestrel now has the ability to observe changes to configuration passed to KestrelServerOptions.Configure and unbind from existing endpoints and bind to new endpoints without requiring you to restart your application.

See the release notes for additional details and known issues.

    Hi there! Does the ASP.NET Core team has any dates or any time limits for fixing asynchronous deserializing IAsyncEnumerable (#1570)? Will the support of it be added to the .NET 5 release? Or later? Will it be available for Core 3.x?
