Overview

This rule identifies incomplete member declarations where a type name can't be resolved in the current context. It's an internal IDE diagnostic that enables code fixes such as Add using, Fully Qualify, and Generate Type.

Note

This rule is not configurable and is primarily an internal diagnostic used to drive IDE code-fix features. You might encounter it as part of IDE functionality, but it isn't intended as a user-facing quality or style rule.

A common scenario is when you start typing a member declaration but the type referenced hasn't been imported. For example, if you type public DateTime without a variable name and without a using System; directive, this rule fires on DateTime to enable the Add using code fix.

Example

// Code that triggers IDE1007.
// 'DateTime' is unresolved because 'using System;' is missing.

class MyClass
{
    public DateTime // incomplete member — 'DateTime' is unresolved
}

Adding the missing using directive or fully qualifying the type resolves the issue:

using System;

class MyClass
{
    public DateTime MyDate { get; set; }
}
