.NET system requirements

Before installing the .NET agent, confirm you can meet the following requirements:

You have administrative access to a server, and the server is supported by Contrast.
There is a deployed application to be analyzed, and the web application technology is supported by Contrast.
The web server has network connectivity with Contrast.
The server meets the minimum requirements (stated below).
.NET Framework: IIS can be restarted.

Requirement	Recommended	Minimum	Notes
CPU	at least 4	2
Memory	at least 8 GB	4 GB	Agents running in Assess roughly double the memory requirements of analyzed applications. Applications should use less than half of the available memory when an agent isn't installed.
Windows operating system	Windows Server (LTSC) (x86, x64): 2012 R2, 2016, 2019, 2022 (.NET Core only) Windows Server (SAC) (x64): 1809, 1903 Windows workstation (x86, x64): 7, 8/8.1, 10	N/A	On 64-bit systems, you can use the agent to analyze both 32-bit and 64-bit web applications. Not supported: macOS Windows on ARM
Linux operating system	Ubuntu: 18.04 and later (x64, ARM64) Debian: 10 and later (x64, ARM64) openSUSE: 15 and later (x64) Alpine: 3.13 and later (x64, ARM64) CentOS: 7 (x64) CentOS Stream 8 (x64) Red Hat Enterprise Linux: 7 and later (x64)	N/A	Not supported: Red Hat Enterprise Linux 6
Processor architecture	32-bit x86 processors 64-bit x86 processors 64-bit ARM processors	N/A	Windows on ARM processors is not supported.
Server container	Windows: Kestrel and IISHttpServer Linux: Kestrel	N/A
Hosting container	Windows: Self-hosted, IIS, IIS Express Linux: Self-hosted	N/A

.NET Framework system requirement notes

The .NET Framework agent uses the CLR Profiling API to perform data and code flow analysis (for example, detect SQL-injection, XSS, weak cryptography) as well as to detect libraries and technologies used by analyzed applications.
The Contrast agent can exist alongside other .NET Profiler agents, such as performance or APM tools with the agent.dotnet.enable_chaining configuration setting enabled.
For servers on earlier versions use the Legacy .NET Framework agent.
