Important

  • .NET Core 2.2 is not supported after the .NET core agent version 1.5.20. If you are using .NET Core 2.2, you'll need to use .NET Core agent version 1.5.20 or lower until you can upgrade your application’s .NET Core runtime.

  • As of .NET core agent version 1.9.9, we no longer support .NET Core 2.1. If you are using .NET Core 2.1, you'll need to use .NET Core agent version 1.9.9 or lower until you can upgrade your application’s .NET Core runtime.

  • As of .NET core agent version 4.8.0, Contrast no longer supports .NET Core 3.1, 5.0, and 7.0. If you are using .NET Core 3.1, 5.0, and 7.0, you'll need to use .NET Core agent version 4.8.0 or lower until you can upgrade your application’s .NET Core runtime.

Note

The .NET Core agent does not support applications that do not reference System.Runtime and ASPNET Core. The agent also does not support trimmed self-contained deployments and executables, because the compiler can potentially trim assemblies that the agent depends on.
