## Metadata{% #metadata %}

**ID:** `csharp-best-practices/variable-names`

**Language:** C#

**Severity:** Warning

**Category:** Code Style

## Description{% #description %}

Avoid using language keywords to declare variables. While being authorized by the compiler, it makes the code harder to understand.

## Non-Compliant Code Examples{% #non-compliant-code-examples %}

```csharp
using System.Net;

class MyClass {
    public static void routine()
    {
        bool await = false;
        bool async = true;
    }
}
```

## Compliant Code Examples{% #compliant-code-examples %}

```csharp
using System.Net;

class MyClass {
    public static void routine()
    {
        // Safe: using descriptive variable names instead of keywords
        bool shouldAwait = false;
        bool isAsync = true;
    }
}
