 On Windows/macOS/Linux, open a terminal in your `csproj` folder and run:
 
 ```shell
-dotnet publish -f net8.0-desktop
+dotnet publish -f net9.0-desktop
 ```
 
 If you wish to do a self-contained publish, run the following instead:
 
 ```shell
-dotnet publish -f net8.0-desktop -r {{RID}} -p:SelfContained=true
+dotnet publish -f net9.0-desktop -r {{RID}} -p:SelfContained=true
 ```
 
 Where `{{RID}}` specifies the chosen OS and Architecture (e.g. win-x64). When targeting Windows, cross-publishing to architectures other than the currently running one is not supported.
