How to get the called address with WCF from inside the service method implementation?

I wish did fix the issue. Maybe OperationContext.Current.EndpointDispatcher.EndpointAddress might have the info you're looking for.

Inside my own Angular service, how do you get the return value back to the Controller that called the service?

around this issue The success and error handlers are specific to the promise returned by $http. However, they're similar to .then(function onFulfill(){}, function onReject(){}).
It's up to you if you want to return that promise directly or implement something else.
code :
app.factory('BooksService', function($http,$log,$q) {
  var service = {
    retrieveAllBooks: function() {
      var deferred = $q.defer();
        method: 'GET','https://hugebookstore.org/allbooks'
        headers: {
            "Content-Type": "application/json",
            "Accept": "application/json"
      }).success(function(data, status, headers, config) {
         var allbooks = transformDataIntoBooksArray(data);//this function exists and just takes raw data and turns them into Book objects
         deferred.resolve( allbooks );
      }).error(function(data, status, headers, config) {
        $log.error('here is an error'+data + status + headers + config);
        deferred.reject( new Error( 'here is an error'+data + status + headers + config );
      return deferred.promise;
  return service;
app.factory('BooksService', function($http) {
  return {
    retrieveAllBooks: function() { 
      return $http.get('https://hugebookstore.org/allbooks').
             then(transformDataIntoBooksArray); // Error tracked by Angular already

Defined service method is not called, instead real service's is called

Hope that helps According to your latest update it is clear that the name of dependency is used wrong in the test. It must be InStudentsService instead of service. When using $inject property of controller constructor only that name matters, not the formal parameter name in function. That makes minification possible
code :
  inStudentsController = $controller('InStudentsController', {
        InStudentsService: MyInStudentsService 

Python instance of class defined inside a method is still able to use local variables inside the method when called outs

will help you You are accessing a closure; i is closed over by the nested scope of bar.show(). The same would happen to variables used by nested functions without a class.
You can see the closure by introspecting the method; I've altered your code a little to just return the class as it simplifies things:
code :
>>> def foo():
...    i = 1
...    class bar( object ):
...       def show( self ):
...          print i
...    return bar
>>> c = foo()()
>>> c
<__main__.bar object at 0x104c7ac90>
>>> c.show
<bound method bar.show of <__main__.bar object at 0x104c7ac90>>
>>> c.show.__func__
<function show at 0x10535c758>
>>> c.show.__func__.__closure__
(<cell at 0x1132a0440: int object at 0x100502818>,)
>>> c.show.__func__.__closure__[0].cell_contents
>>> foo.__code__.co_cellvars
>>> import dis
>>> dis.dis(foo)

TransactionScope does not rollback inside wcf service method, does roll back if called directly

will be helpful for those in need You tagged your post with the DevArt and DotConnect tags... I wonder if this is a bug in the DevArt providers rather than something inherent to WCF / Entity Framework / System.Transactions. You could test the theory by seeing if it happens with a ObjectContext that is using the built-in SQL Server Provider (or even Oracle's own EF provider that was recently released) and see if the issue still occurs. That is the only thing I can think of since the code seems 100% correct.
