I am worry about the implementation here, does it only work for one level? I mean $it/Product? Do we work: $it/Address/City

It should support $it/Address/City
I will add tests to validate that.

translatedNode = leftBinary + binaryOperator + rightBinary; [](start = 20, length = 59)
If it's not a difference source, we should return the existing string "translateNode".

| string translatedNode = this.TranslateNode(filterClause.Expression); | ||

can we refactor the implementation here?
- separate the whole into methods
- Use the traverse, for example: https://github.com/OData/WebApi/blob/master/src/Microsoft.AspNet.OData.Shared/Query/Expressions/FilterBinder.cs#L184

Alternatively,
BinaryOperatorNode binaryNode;
// ... other variable declarations
if ((binaryNode = node as BinaryOperatorNode) != null)
{
// ...
}
// else if ...I however don't know if the cost of doing all 5 explicit conversions using the as operator regardless is significant. In this case it might not matter since the most common scenario is handled by the else block and all the explicit conversions will have been done either way.

Let me hear the opinions of others on this.

I had the same thought -- we want to limit the number of casts.
Can we switch on QueryNode.Kind (or QueryNode.InternalKind)?

IsDifferentSource(filterClauseRangeVariable, leftRangeVariableNode) [](start = 49, length = 67)
So this logic is assuming that, if the range variable is a different source, the range variable must be $it, right? In which case, $this would work because it's the same type as the filterClauseRangeVariable so it will just fall through? How would this logic change when if we supported $root?
Minimally, we need to document these assumptions and add tests (if they don't already exist) for these different cases.

This logic only needs to execute if the sources are different, so it would be better to move it within your if statement.

all of this logic should be moved inside the conditional and only executed in the case that we are inserting the $it.

could simplify to:
return filterClauseRangeVariable.NavigationSource != rangeVariableReferenceNode.NavigationSource;
| Uri queryUri = new Uri("People?$expand=MyDog($filter=endswith($it/Name,'abcd'))", UriKind.Relative); | ||
| Uri actualUri = UriBuilder(queryUri, ODataUrlKeyDelimiter.Parentheses, settings); | ||
| Assert.Equal("http://gobbledygook/People?$expand=" + Uri.EscapeDataString("MyDog($filter=endswith($it/Name,'abcd'))"), actualUri.OriginalString); | ||
| } |

do we have variants of each of these that don't use $it, and instead assume the range variable of the filter clause?

A few comments, otherwise looks good. |
