Product Description

Microsoft .NET is a software development framework.

Software Pattern Summary

Platforms Supported by Software Pattern

Microsoft .NET runs on Windows only.  So this pattern supports Windows only.

Identification & Versioning

All patterns trigger on all Windows hosts.

Microsoft .NET Framework

Powershell

We get a list of versions of Microsoft .NET Framework installed on the system from the following PowerShell command: RuntimeInformation.FrameworkDescription

Registry

We get a list of Microsoft .NET Framework versions installed on the system from the following registry keys (this follows the advice in Microsoft documentation):

• HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\NET Framework Setup\NDP\\v4\\Full\\Release (covers versions 4.5 to 4.8)
• HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\NET Framework Setup\NDP\\v4\\Full\\Version (covers version 4.0)
• HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\NET Framework Setup\NDP\\<version_dir>\\Install (for each version 1.1, 2.0, 3.0, 3.5)
• HKEY_LOCAL_MACHINE\Software\Microsoft\Active Setup\Installed Components\{78705f0d-e8db-4b2d-8193-982bdda15ecd}\Version (covers version 1.0).

For versions between 1.1 and 4.0, we will only create a RuntimeEnvironment node if there is a matching Microsoft .NET package with the same version.  If a version is uninstalled the old registry key may remain, but the old package version is less likely to.

Package

The pattern with create RuntimeEnvironment for every version that has a package name that starts “Microsoft .NET Framework”.

Microsoft .NET Core

The pattern creates a RuntimeEnvironment node for every .NET Core version listed in command %programfiles%\dotnet\dotnet.exe --info (%programfiles% is a system environment variable).

The pattern also created a RuntimeEnvironment node for every version that has a package name that starts “Microsoft .NET Core Runtime”.

Microsoft .NET Common Language Runtime

The pattern creates a RuntimeEnvironment node for every .NET Core version listed in powershell command $PSVersionTable.CLRVersion.

Application Model Produced by Software Pattern

Architecture

The pattern creates RuntimeEnvironment nodes for the following types:

• Microsoft .NET Framework is a proprietary software framework developed by Microsoft that runs primarily on Microsoft Windows (see wikipedia)
• Microsoft .NET Core “is a free and open-source, managed computer software framework for Windows, Linux, and macOS operating systems. It is a cross-platform successor to .NET Framework” (see more details in Wikipedia).
• Microsoft .NET Common Language Runtime - each version of .NET Framework contains the common language runtime (CLR) (see Microsoft documentation).

SI Depth

The pattern creates a RuntimeEnvironment node for every version of every time it finds.  It adds the architecture to the key if applicable.

Relationship Creation

The pattern creates a dependency relationship from the CLR RE to the Framework RE on the same host (the CLR RE in the dependant).

A relationship will only be created if these version conditions match. More details are provided in the Microsoft document documentation.
