+# How to upgrade from .NET 8 to .NET 9
+
+Migrating from .NET 8 to .NET 9 is a generally straightforward process. You may find below some specific adjustments to make to your projects and libraries when upgrading.
+
+To upgrade to .NET 9:
+
+- First, read [What's New in .NET 9](https://learn.microsoft.com/dotnet/core/whats-new/dotnet-9/overview)
+- Install [Visual Studio 17.12 Preview 3](https://visualstudio.microsoft.com/vs/) or later and run [uno.check](xref:UnoCheck.UsingUnoCheck) with the `--pre-major` parameter to install .NET 9.
+- Change all your target framework (TFM) references from `net8.0` to `net9.0`, and `net8.0-*` to `net9.0-*`.
+- Delete your bin and obj folders
+
+## Considerations for WebAssembly
+
+WebAssembly support for .NET 9 has made significant internal changes to use the official .NET SDK. Read the following [documentation for WebAssembly migrations](https://aka.platform.uno/wasm-net9-upgrade).
