Automatically implemented properties

Introduction

Automatically implemented properties make property declaration more concise, where no other logic is required in property accessors. The compiler creates a private and anonymous storage field that can only be accessed by the property's get and set accessors.

Generating automatically implemented properties

In order to allow the declaration of properties using simplified syntax, you must first specify version 3.x of the language in the C# Developer "Général" parameter set (as shown below).

The "SDK Version" parameter set to version 3.x

This new feature of the C#3.0 language can subsequently be activated or deactivated using the "Authorize automatically implemented properties" parameter in the "Code generation" set.

The "Authorize automatically implemented properties" parameter

To obtain the property declaration with simplified syntax, you must not define any associated code notes (CsGetCode/CsSetCode), as if you do, a normal property will be generated.

The generator will automatically apply the "private" modifier (by default) to the get or set accessor according to which access mode has been selected, as shown in the table below.

Access mode / Modifiers	None	Read	Write	ReadWrite
get	Error	Warning	CsPropertyVisibilityGet or private	Warning or Error
set	Error	CsPropertyVisibilitySet or private	Warning	Warning or Error

Note: You can change the default modifier of get and set accessors using the corresponding "CsPropertyVisibilityGet" and "CsPropertyVisibilitySet" tagged values.
