Depending on the context, “Detect DotNet” typically refers to KopiCloud DetectNET, a lightweight, open-source C# utility designed to identify all installed versions of both legacy .NET Framework and modern .NET Core/Modern .NET on a Windows machine.
Alternatively, if you are looking to detect .NET environments natively, the phrase refers to the broader programmatic, command-line, or system processes used to identify .NET runtimes. 1. KopiCloud DetectNET Tool
Developed by IT professional Guillermo Musumeci, DetectNET was built to solve the frustration of manually checking fragmented registry keys and file folders to see which .NET versions are active.
Unified Detection: Unlike standard tools that only scan legacy framework paths, this tool checks both the modern .NET Core/6/7/8/9/10 eco-systems and old .NET Framework (1.0 to 4.8) installations simultaneously.
No Dependencies: It is compiled as a native executable, meaning it doesn’t require a pre-installed version of .NET just to run and inspect your system.
Open Source: The full code repository is publicly available on the Guillermo Musumeci GitHub Project. 2. Manual Command-Line Detection
If you are looking to detect .NET without a third-party application, you can use built-in terminal utilities: Modern .NET (.NET Core & newer)
Open your Command Prompt or PowerShell and run the following standard commands:
dotnet –version — Outputs the current active .NET SDK version.
dotnet –list-runtimes — Displays all installed .NET runtimes (e.g., ASP.NET Core, Desktop, or Base Runtimes).
dotnet –list-sdks — Shows all installed Software Development Kits. Legacy .NET Framework
Legacy versions (4.x and older) store their versioning data inside the Windows Registry rather than accessible environment paths. To find them via PowerShell (run as Administrator), execute this query: powershell
Get-ChildItem ‘HKLM:\SOFTWARE\Microsoft\NET Framework Setup\NDP’ -Recurse | Get-ItemProperty -Name version -EA 0 | Where { $_.PSChildName -Match ‘^(?!S)\p{L}’} | Select PSChildName, version Use code with caution. 3. Programmatic Detection (For Developers)
If you are writing code and need your app to conditionally change behavior depending on what platform it is executing on, you can test for the existence of specific types that only exist in newer cross-platform runtimes. For example:
public static bool IsRunningOnDotNetCore => Type.GetType(“System.Runtime.Loader.AssemblyLoadContext”) != null; Use code with caution. 4. Alternative Third-Party Integrations
If your inquiry relates to software scanning, dependency management, or build auditing, “Detect DotNet” might pop up in these contexts:
ASoft .NET Version Detector: A popular third-party graphical user interface utility that scans your machine for .NET versions alongside relevant Windows KB updates.
Black Duck (Synopsys Detect): An enterprise Software Composition Analysis (SCA) tool that utilizes a package-manager module known as the NuGet/DotNet detector to map open-source code compliance and vulnerabilities during build cycles.
Are you trying to troubleshoot a specific application that requires a certain version of .NET, or are you looking to bundle a dependency detector inside an application installer you are currently building? Nuget detector –detect.dotnet.path is deprecated
