20. ❖ Command-line tool support
➢ .NET Core provides the command line, which support all major platforms like
Windows, Mac and Linux.
➢ .NET Core fully supports command line tool which is useful in complete cycle
of development (create new project, add package, build, run etc.)
➢ It is also referred to as a foundational tool because it’s a primary layer on
which other tools like IDE (Integrated Development Environments) build the
application and run it.
Benefits and Features contd.

24. ❖ Flexible deployment
● There can be two types of deployment for .NET Core applications
➢ Framework-dependent deployment (IIS, Apache, Docker)
➢ Self-contained deployment (Exe)
Benefits and Features contd.

25. ❖ Support for Cloud-Based Development
➢ For better security and overall performance, it is better to develop
your enterprise application as cloud-based.
➢ .NET Core functionality is excellent for this.
➢ The framework has been designed to take full advantage of
accessing the Cloud and your applications will be all the better for
it.
Benefits and Features contd.

26. ❖ Performance
➢ The most important feature of ASP.NET Core is probably its higher performance
when compared to other platforms.
➢ When you compile your code, it automatically optimize it in order to increase the
performance.
➢ The best part about this particular benefit is that you do not have to change your
code. With the re-compilation it optimizes the code directly.

properties to declare which UI framework is being used:
For WPF:
<Project Sdk="Microsoft.NET.Sdk.WindowsDesktop">
<PropertyGroup>
<OutputType>WinExe</OutputType>
<TargetFramework>netcoreapp3.0</TargetFramework>
<UseWPF>true</UseWPF>
</PropertyGroup>
</Project>
