Build your first Aspire app

Build your first Aspire app by first choosing the AppHost language you want to work in. The AppHost is the code-first orchestrator for your solution, so this choice lets you stay in a familiar toolchain while deciding whether your walkthrough uses AppHost.cs / apphost.cs or apphost.ts.

[!NOTE] Start with the AppHost language Choose the AppHost language that matches the toolchain you want to use for the orchestration layer. Either AppHost can orchestrate apps in multiple languages.

Before you begin

Before following either quickstart, make sure you've completed the prerequisites and installed the Aspire CLI.
