Key Features of .NET Aspire 9

1. Simplified Installation and Upgrades

.NET Aspire 9 makes it very easy to get started. You can now install the new .NET Aspire SDK directly into app host projects. You do not need a separate .NET workload to install it.

Developers can also access updated project templates as individual NuGet packages. To do this, simply enter the following command:

dotnet new install Aspire.ProjectTemplates::9.0.0

dotnet new install Aspire.ProjectTemplates::9.0.0 –force

Then, we can have the latest .NET Aspire templates.

This modular approach ensures that you always have access to the latest tools without unnecessary dependencies.
