Actionable insights to solve .NET errors.

**Documentation:** [https://docs.sentry.io/platforms/dotnet/](https://docs.sentry.io/platforms/dotnet/)

## Features

### .NET Error Monitoring with Complete Stack Traces

See .NET stack trace details like filename and line number so you never have to guess. Filter and group .NET exceptions intuitively to eliminate noise. Monitor errors at scale without impacting throughput in production.

### Performance Monitoring Across Services

Quickly identify .NET performance issues before they become downtime with [performance monitoring](/product/tracing/). View the entire end-to-end distributed trace to see the exact, poor-performing API call and surface any related errors.

### Fill In The Blanks

Expose the important events that led to each .NET exception: debug logs, network requests, database queries, past errors.

### See the Full Picture of Any Exception

With Sentry's exceptional exception handling in .NET, you can triage quickly based on specific parameters like HTTP request, workflow stage, and hostname for each issue. Set custom tags to recreate the error environment relevant to your app, business concerns, and users.

### Your Logs, Next to the Trace

Route Serilog, NLog, log4net, or Microsoft.Extensions.Logging output into Sentry and query it beside your [traces](/product/tracing/) and exceptions. The logging you already have becomes searchable context on the request that failed.

## FAQ

**What is the difference between Sentry and traditional logging?**

Traditional logging provides you with a trail of events. Some of those events are errors, but many times they're simply informational. Sentry is fundamentally different because we focus on exceptions, or in other words, we capture application crashes. We discuss in more detail [here](/vs/logging/) and on our [blog](https://blog.sentry.io/lets-get-ready-to-monitor/).

**How do I connect issues to git commits?**

When Spring Boot is configured to generate Git information every event triggered by Sentry will have a release field set to the current Git commit ID that will enable Monitor Release Health Sentry feature. More details [here](https://docs.sentry.io/platforms/java/guides/spring-boot/#using-git-commit-id-as-the-release).

**How much does Sentry cost?**

You can get started for free. Pricing depends on the number of monthly events, transactions, and attachments that you send Sentry. For more details, visit our [pricing page](/pricing/).

**Which .NET frameworks does Sentry support?**

The Sentry .NET SDK covers [ASP.NET Core](/for/aspnetcore/) and [ASP.NET](/for/aspnet/), [MAUI](/for/dotnet-maui/), Blazor (both Interactive SSR and WebAssembly), Entity Framework, WPF, Windows Forms, WinUI and Xamarin, and runs on Windows, macOS, Linux, Android and iOS.

It integrates with Serilog, NLog, log4net and Microsoft.Extensions.Logging, and supports AWS Lambda, Azure Functions and Google Cloud Functions for serverless workloads.

**Can I send logs to Sentry?**

Yes. Sentry Logs lets you send, view, and query structured logs from your application alongside your errors and traces. Because logs sit next to the error and the trace that produced them, you get the granular context — retries, API failures, internal state — that spans and stack traces alone can miss, without switching tools.

**What is Seer, Sentry's AI debugging agent?**

Seer is Sentry's AI debugging agent. It reads the full context Sentry already has — the error, its stack trace, the surrounding trace, logs, and profiles — to find the root cause of an issue and propose a fix. Seer can open a pull request with that fix, hand the work to an external coding agent, or review your PRs before they ship.
