The API Server requires Microsoft Hosting Bundle 2.1 installed without the runtime program. The API Server installer installs the ASP.NET Core Hosting Bundle 2.1.30 if a newer 2.1.x version isn't already installed.
Note: Support for ASP.NET Core 2.1 on .NET
Framework matches the ASP.NET Support policy for other package-based ASP.NET frameworks.
The complete list of packages covered by this policy can be seen in ASP.NET Core 2.1 Supported Packages.
The .NET Framework and Hosting Bundle is a Microsoft product. For additional installation and configuration procedures, see the Microsoft documentation.
