Microsoft's .NET Framework has gained significant traction since its introduction in 2002, with a large user base including notable organizations. The rise of the .NET Core runtime has expanded its reach to cross-platform development. Datadog APM now supports both .NET Framework and .NET Core applications, providing deeper visibility into these environments. This addition brings .NET into line with other supported frameworks and languages in APM. Datadog's .NET client automatically instruments various data stores, web frameworks, and databases, making it easy to integrate and monitor .NET applications without code changes. The platform offers features such as the Service Map, service overview dashboards, App Analytics, Watchdog, and flame graphs to analyze and understand application performance in real-time. These tools help identify dependencies between services, optimize application performance, investigate issues, and provide customer-level visibility. Datadog's integration with cloud services like Azure and AWS enables monitoring of both .NET applications and infrastructure in one place, making it easier to connect the dots across environments.
