I updated a library project method,

```
public static void EatFruit(string a, string b)

```

to 

```
public static void EatFruit(string a, string b, bool IsEatFruit = false)

```

Now there are hundred of projects using this library, Do I need to update references of library dll in all projects and solutions ?

I updated the server and they all are failing by this error,

> 
> Method not found void EatFruit(System.String, System.String)'.
