Requires IIS (Internet Information Services) to be installed

This package was approved as a trusted package on 7/9/2019.

.NET Core is a general purpose development platform maintained by Microsoft and the .NET community on GitHub. It is cross-platform, supporting Windows, macOS and Linux, and can be used in device, cloud, and embedded/IoT scenarios.

This package installs the ASP.NET Core Module for IIS, enabling running of ASP.NET Core applications. IIS must be enabled prior to installing this package. ASP.NET Core does not use any managed IIS modules, so no ASP.NET IIS features need to be enabled.

The native installer is instructed to skip installing the .NET Core Runtime (OPT_INSTALL_LTS_REDIST=0 OPT_INSTALL_FTS_REDIST=0). The package dotnetcore-runtime should be used to install the runtime when hosting "portable" ASP.NET Core applications (which use the machine-wide runtime). Hosting of "self-contained" ASP.NET Core applications does not require the runtime to be installed, because those applications include the desired runtime as part of their binaries.

The package supports the following parameters (--package-parameters, --params):

  • Quiet - suppress display of native installer progress window (may be needed on Server Core)
  • IgnoreMissingIIS - allow package installation even if IIS is not present (probably useless, as the native installer will not install anything)

Example: cinst -y --params="Quiet IgnoreMissingIIS" dotnetcore-windowshosting

To install Microsoft .NET Core - Windows Server Hosting, run the following command from the command line or from PowerShell:

C:\> choco install dotnetcore-windowshosting --version 2.2.6

To upgrade Microsoft .NET Core - Windows Server Hosting, run the following command from the command line or from PowerShell:

Virus Scan Results

In cases where actual malware is found, the packages are subject to removal. Software sometimes has false positives. Moderators do not necessarily validate the safety of the underlying software, only that a package retrieves software from the official distribution point and/or validate embedded software against official distribution point (where distribution rights allow redistribution).

Chocolatey Pro provides runtime protection from possible malware.
