is a Long-Term Support (LTS) release (supported for three years). It includes performance improvements, native AOT compilation, and enhanced security features. Part 2: Does Citrix Workspace Require .NET Core 8.0 or Later? Short answer: No — Citrix Workspace App itself does not require .NET Core 8.0 or later for its basic operation. The core ICA/HDX client runs as a native Windows process with minimal external dependencies.

However, certain components, add-ons, and integrations that work alongside Citrix Workspace do require .NET runtime dependencies — specifically .NET Framework 4.7.2 or later. But starting with Citrix Workspace App version 2305 and newer, Citrix has been gradually moving some supporting utilities toward .NET 6.0 and now .NET 8.0 . Where .NET 8.0+ appears in a Citrix environment: | Component | .NET Dependency | Notes | |-----------|----------------|-------| | Citrix Workspace App (core) | None | Native C++ client | | Citrix VDA (Virtual Delivery Agent) | .NET Framework 4.7.2+ | Not .NET Core | | Citrix Workspace Environment Management (WEM) Agent | .NET 6.0+ | Starting WEM 2305 | | Citrix Cloud Connector | .NET Framework 4.8 | | | Citrix Director Console | .NET 8.0 (optional) | For modern reporting | | Custom SDKs (StoreFront SDK, Powershell) | .NET 6.0/8.0 | For automation scripts | | Workspace App for Linux (Dependency) | .NET Core runtime | For certain SSO features |

This article provides a deep dive into the relationship between Citrix Workspace and .NET Core 8.0+, clarifying dependencies, installation best practices, troubleshooting common errors, and future-proofing your virtual app and desktop environment.
