You can enable App and API Protection for .NET services with the following setup options:

If your .NET service already has APM tracing set up and running, then skip to service configuration.
If your .NET service doesn't have APM tracing set up, you can easily enable App and API Protection with Datadog's Automatic Installation.
Otherwise, continue reading the manual setup instructions below.

Overview

App and API Protection leverages the Datadog .NET library to monitor and secure your .NET service. The library integrates seamlessly with your existing application without requiring code changes.

For detailed compatibility information, including supported DOTNET versions, frameworks, and deployment environments, see .NET Compatibility Requirements.

This guide explains how to set up App and API Protection (AAP) for .NET applications. The setup involves:

Installing the Datadog Agent.
Enabling App and API Protection monitoring.
Running your .NET application with the Datadog Agent.
Verifying the setup.

Prerequisites

Kubernetes cluster
.NET application containerized with Docker
kubectl configured to access your cluster
Helm (recommended for Agent installation)
Your Datadog API key
Datadog .NET tracing library (see version requirements)

1. Installing the Datadog Agent

Install the Datadog Agent by following the setup instructions for Kubernetes.

2. Enabling App and API Protection monitoring

Automatically enabling App and API Protection through Remote Configuration

You can enable remote configuration on your services dashboard. Simply check the box for the service you want to enable App and API Protection for under "Activate on your APM services".

Manually enabling App and API Protection monitoring

Ensure your Dockerfile includes the Datadog .NET library:

# Download and install Datadog .NET Tracer
ENV DD_TRACE_VERSION=3.20.0
RUN curl -sSL https://github.com/DataDog/dd-trace-dotnet/releases/download/v${DD_TRACE_VERSION}/datadog-dotnet-apm-${DD_TRACE_VERSION}.linux-x64.tar.gz \
    | tar -xz -C /opt/datadog

# Set environment variables for Datadog automatic instrumentation
ENV CORECLR_ENABLE_PROFILING=1 \
    CORECLR_PROFILER="{846F5F1C-F9AE-4B07-969E-05C26BC060D8}" \
    CORECLR_PROFILER_PATH=/opt/datadog/Datadog.Trace.ClrProfiler.Native.so \
    DD_DOTNET_TRACER_HOME=/opt/datadog \

APM Tracing Enabled

Update your Kubernetes deployment to include the required environment variables:

apiVersion: apps/v1
kind: Deployment
metadata:
  name: your-dotnet-app
spec:
  template:
    spec:
      containers:
      - name: your-dotnet-app
        image: your-dotnet-app-image
        env:
        - name: DD_APPSEC_ENABLED
          value: "true"
        - name: DD_SERVICE
          value: "<MY_SERVICE>"
        - name: DD_ENV
          value: "<MY_ENV>"

APM Tracing Disabled

To disable APM tracing while keeping App and API Protection enabled, you must set the APM tracing variable to false.

Update your Kubernetes deployment to include the required environment variables:

apiVersion: apps/v1
kind: Deployment
metadata:
  name: your-dotnet-app
spec:
  template:
    spec:
      containers:
      - name: your-dotnet-app
        image: your-dotnet-app-image
        env:
        - name: DD_APPSEC_ENABLED
          value: "true"
        - name: DD_APM_TRACING_ENABLED
          value: "false"
        - name: DD_SERVICE
          value: "<MY_SERVICE>"
        - name: DD_ENV
          value: "<MY_ENV>"
