Aspire Toolkit Overview
What It Is
The Aspire toolkit helps you manage full-stack apps while you build them. You can organize, run, and watch all parts of your app on your own computer. This includes the frontend, backend, databases, and services. The toolkit puts everything you need in one place. You can build, test, and check distributed systems without extra setup or needing the cloud.
When you use the Aspire toolkit, you get three main things:
Orchestration: You can put many projects together in one solution. You use C# code to show how your app fits and how services connect. This makes it simple to handle big systems.
Components: These are blocks you can use again. They can be your code or things like databases and APIs from others. Components have default settings, work with dependency injection, and let you see data and find services.
Tooling: The toolkit gives you templates to start new projects fast. You also get defaults like OpenTelemetry, health checks, and a dashboard to watch your app. If you use JetBrains Rider, there is a plugin for better use.
The Aspire toolkit is special because it helps you work on your own computer. You do not need to write YAML files or move your app to a new platform. You just use one command to start your whole stack, no matter what language or framework you use.
Why It Matters
Building modern apps is hard. You have to handle microservices, databases, and cloud services. This can be too much sometimes. The Aspire toolkit makes local orchestration easy and steady.
Here is why the Aspire toolkit is good for your work:
You can start your whole app with one command. This saves time and stops mistakes.
The toolkit gives you a dashboard. You can see logs, health checks, and traces in one spot. This helps you fix problems faster.
Aspire toolkit lets you use different resources. You can use local containers, cloud services, or fake ones if you want.
Observability is built in. The toolkit collects logs, metrics, and traces with OpenTelemetry. You can see how your system is doing.
Health checks happen by themselves. Every service and dependency gets a health check and status.
The toolkit is easy to change and add to. You can put in new components or use tools like Kubernetes, Dapr, or AI workflows.
Aspire toolkit helps you work faster. You spend less time setting up and more time making features. Teams say they build faster, have fewer bugs, and new people learn quicker.
Tip: Aspire toolkit lets you build and run your whole app on your computer. This is like your real environment and helps stop surprises when you launch.
You can use the Aspire toolkit for many things. It is good for handling microservices, making cloud-native apps, helping developer platforms, and quick testing. Companies see real gains, like faster building, lower cloud bills, and better app speed.

Built-In Dashboard
Aspire toolkit gives you a strong dashboard to watch and manage your app. You can see logs, traces, and metrics as they happen. The dashboard lets you start, stop, and restart resources with one click. You can use different input types like text, numbers, or dropdowns. The dashboard helps you keep secrets and settings safe. It has an AI helper powered by GitHub Copilot. This helps you debug and learn about your app. Other tools need extra dashboards, but Aspire’s dashboard is built in. It is made for developers. You get theme choices, keyboard shortcuts, and interactive controls in one spot.
Dev-First Experience
Aspire toolkit is made for developers. You get project templates and tools for Visual Studio and the dotnet CLI. You can start new projects fast and handle many services at once. The toolkit sets up telemetry, health checks, and service defaults for you. You do not need to write extra code or change how you deploy. Aspire automates service discovery, environment variables, and container setup. You can use it with new or old projects. The toolkit supports cloud-native apps that can grow and recover easily. OpenTelemetry gives you deep insights into your app’s performance. Health checks and resiliency features are on by default, but you can change them if you want.
Note: Aspire toolkit lets you focus on building features. It takes care of orchestration, monitoring, and configuration for your whole stack.
Integrations

Getting Started
Installation
You can put Aspire on most new devices. The steps are easy. You do not need the cloud or YAML files. You just need the right operating system and a browser. The table below lists what you need to install Aspire:
You need fast internet and sound turned on. Netbooks and Windows Mobile do not work with Aspire. Most people finish installing in 20 to 60 minutes if they skip updates. If you get updates while installing, it can take a few hours.
Configuration
Aspire lets you set things up in many ways. You can use command line arguments, environment variables, or JSON files. You can set limits for logs, traces, and metrics with environment variables. You can also use shared files for all your projects. Aspire lets you set up with code, so it is quick and the same every time.
You can change Aspire projects with JSON files like
appsettings.Base.json
, environment variables, and command line arguments. Shared files help keep all services working together. Extension methods let you set base paths and pick the order for loading files.
For example, you can set telemetry limits with environment variables in Docker:
docker run --rm -it -p 18888:18888 -p 4317:18889 -d --name aspire-dashboard \
-e DASHBOARD__TELEMETRYLIMITS__MAXLOGCOUNT='1000' \
-e DASHBOARD__TELEMETRYLIMITS__MAXTRACECOUNT='1000' \
-e DASHBOARD__TELEMETRYLIMITS__MAXMETRICSCOUNT='1000' \
mcr.microsoft.com/dotnet/aspire-dashboard:9.4
You can also use JSON files to set these limits.
