See the following table to select the correct download.
| OS | Development Environment | .NET Core SDK |
|---|---|---|
| Windows | Visual Studio 2017 | 2.1.524 |
| macOS | Visual Studio for Mac | Visual Studio for Mac .NET Core Support |
Note: This is not a security release hence this update won't be immediately available through Visual Studio. However, this is expected to show up in Visual Studio's January servicing release.
Notable Changes
.NET Core 2.1.28 release carries only non-security fixes.
Behavioral change in Asp.Net 2.1 Installers
Asp.Net 2.1.28 will now install side-by-side with Asp.Net 2.1.6 or earlier. It will still remove previously installed versions of Asp.Net that are 2.1.7 or newer. Users runnning the 2.1.28 Asp.Net Installer or 2.1.28 Hosting Bundle should manually uninstall any local versions of the Asp.Net runtime that are 2.1.6 or earlier.
