Install And Prerequisites

Install is intentionally small.

Install package

bash.sh

dotnet add package Tessera

Most public apps only need this package to start.

Optional project bootstrap

bash.sh

dotnet new console -n MyApp -f net10.0
cd MyApp
dotnet add package Tessera

Environment requirements

• .NET 10 SDK (from global.json)
• terminal with reliable ANSI/CSI support
  • Ghostty
  • iTerm2
  • Windows Terminal
  • macOS Terminal

Advanced runtime lane

Tessera.Core namespaces are the low-level runtime layer, shipped inside the same Tessera package. Most beginner apps stay in the primary Tessera namespaces.

Default namespaces to import

Most app code should start with:

csharp.cs

using Tessera;
using Tessera.Controls;
using Tessera.Layout;

Add using Tessera.Styles; when theme, color, or style work starts to matter.

Next step

• starting from empty folder: Quickstart (New App)
• integrating into an existing project: Quickstart (Existing App)
• then continue to Your First App and Starter Examples
