Question

I have 2 extension methods that convert a MongoDB document to an entity/object.

public static ProductTemplate Convert(this Document document)
{
    return null;
}

public static Product Convert(this Document document)
{
    return null;
}

This gives an expected ambiguous call error so I was wondering how I could fix this?

Friendly greetings,

Functions can’t be overloaded by return type. You will have to rename your functions to maybe:

ConvertToProductTemplate()
and
ConvertToProduct()

or turn them into one function which returns a common base class or interface. (But then the caller will have to do a cast when they get your result)
