Use `var` instead of explicit type declarations when the type is clear from the context.

Good:
```
var name = "John";
```

Bad:
```
string name = "John";
```

Do not use underscores in front of private fields.

Good:
```
private readonly string name;
```

Bad:
```
private readonly string _name;
```
