Debugging Uno Platform Solution templates

The uno platform project contains multiple types of templates:

• dotnet new templates
• Visual Studio (2022/2026) Extensions templates (vsix)

Some of the templates are reusing the same sources. For example the full solution template is defined in the vsix project, and building the dotnet new template creates a transformed version of the vsix template.

dotnet new templates

dotnet new new templates use the dotnet/templating engine, and are located in the src/SolutionTemplate/Uno.ProjectTemplates.Dotnet folder.

To make modifications to those templates and test the result:

• In Visual Studio, open the solution using the Uno.UI-SolutionTemplates.slnf filter
• Right click on the Uno.ProjectTemplates.Dotnet project, select Pack
• This will create a Uno.ProjectTemplates.Dotnet.255.255.255.255.nupkg file
• Install this file using dotnet new -i C:\[your_path]\bin\Debug\Uno.ProjectTemplates.Dotnet.255.255.255.255.nupkg
• In another temporary folder, create a new application using the updated templates with dotnet new unoapp -o MyTestUnoApp01

Ensure that the application runs properly by building it in Visual Studio and running it on all targets.

Once you're done with debugging the templates, you can go back to the official templates with:

dotnet new -i Uno.ProjectTemplates.Dotnet
