A quick overview of C# 10.0 desktop application templates

One of the areas where Microsoft has made big changes in C# 10.0 is in the ability to run applications just about anywhere given the proper pre-requisites. Consequently, it’s important for a developer to know which templates are available and which platforms they support.

The following table makes it easier for you to find a particular template for desktop development. Note that this list assumes that you’re working with C# and not some of the other languages that Visual Studio 2022 supports.

Project Type Supported Environments Description
Blank App (Universal Windows) Windows, Xbox, UWP, Desktop Allows creation of applications using the new Universal Windows Platform (UWP) approach. The template doesn’t provide any underlying application files.
Empty Project (.NET Framework) Windows, Desktop Allows creation of Windows Forms applications. The template doesn’t provide any underlying application files. Note that this template uses older versions of the .NET Framework.
NUnit Test Project Linux, macOS, Windows, Desktop, Web Provides the means to test your applications no matter where they might reside. The same testing process works on both the Web and on the Desktop.
Shared Project Windows, Desktop Allows the creation of code that spans multiple projects. The goal is to allow building of the code differently based on the project in which it resides. You can learn more about this template type at https://docs.microsoft.com/visualstudio/extensibility/migration/update-visual-studio-extension.
Windows Application Packaging Project Windows, UWP, Desktop Creates an application package that is contained in a .msix file. The goal of this project is to create an application you can distribute through the Microsoft Store.
Windows Forms App Windows, Desktop Creates a traditional Windows Forms application for use in the desktop environment. This template lets you use the newer .NET Framework 5.0 and above features.
Windows Forms App (.NET Framework) Windows, Desktop Creates a traditional Windows Forms application for use in the desktop environment. Note that this project uses older versions of the .NET Framework.
Windows Forms Class Library Windows, Desktop, Library Allows development of reusable code modules for Windows Forms applications.
Windows Forms Control Library Windows, Desktop, Library Makes it possible to create custom or user controls for use in Windows Forms applications. This template lets you use the newer .NET Framework 5.0 and above features.
Windows Forms Control Library (.NET Framework) Windows, Desktop, Library Makes it possible to create custom or user controls for use in Windows Forms applications. Note that this template uses older versions of the .NET Framework.
Windows Service (.NET Framework) Windows, Desktop, Service Provides the means for creating an application that runs in the background as a service. Service setups are accessed through the Services MMC, rather than directly through a user interface. Note that this template uses older versions of the .NET Framework.
WPF App (.NET Framework) Windows, Desktop Uses the newer Windows Presentation Foundation (WPF) approach to creating applications. Note that this template uses older versions of the .NET Framework.
WPF Application Windows, Desktop Uses the newer Windows Presentation Foundation (WPF) approach to creating applications. This template lets you use the newer .NET Framework 5.0 and above features.
WPF Browser App (.NET Framework) Windows, Desktop Allows creation of a browser-like application for the desktop using the WPF approach. Note that this template uses older versions of the .NET Framework.
WPF Class Library Windows, Desktop, Library Allows development of reusable code modules for WPF applications.
WPF Custom Control Library Widows, Desktop, Library Makes it possible to create custom controls for use in a WPF application. This template lets you use the newer .NET Framework 5.0 and above features.
WPF Custom Control Library (.NET Framework) Windows, Desktop, Library Makes it possible to create custom controls for use in a WPF application. Note that this template uses older versions of the .NET Framework.
WPF User Control Library Windows, Desktop, Library Makes it possible to create user controls for use in a WPF application. This template lets you use the newer .NET Framework 5.0 and above features.
WPF User Control Library (.NET Framework) Windows, Desktop, Library Makes it possible to create user controls for use in a WPF application. Note that this template uses older versions of the .NET Framework.

 

C# 10.0 keyword listing

All programming languages rely on keywords — words that are reserved and that you can’t use for your personal needs. Knowing the keywords makes it possible for you to choose other words for your code. For example, you couldn’t create a variable named “while” because it’s a C# keyword. The following table contains the C# keywords.

abstract as base bool break
Byte case catch char checked
class const continue decimal default
delegate do double else enum
event explicit extern false finally
fixed float for foreach goto
if implicit in int interface
internal is lock long namespace
new null object operator out
override params private protected public
readonly ref return sbyte sealed
short sizeof stackalloc static string
struct switch this throw true
try typeof uint ulong unchecked
unsafe ushort using virtual void
volatile while
