Entity frameworks notes

if you get such error while serialize your entity ".......System.Data.Entity.DynamicProxies is not expected."
after creating your entity context (generated class derived from DbContext) the next line:

 base.Configuration.ProxyCreationEnabled = false;

to solve the error of
DataContractJsonSerializer  "reference tracking is disabled" 
i remove some of my association i created to avoid back reference

To get the SQL query that generated by db entity use:
var sql = ((System.Data.Entity.Infrastructure.DbQuery<tbl_artists>)query).ToString();
if its object:
var sql = ((System.Data.Objects.ObjectQuery)result).ToTraceString();

IIS Express - access from android while debugging

i am working on end to end project , need to build the android UI and the web services.
while building the webservice via .NET i wanted to test them via my device connected to my usb.

i noticed i failed to access the IISEXpress ,only localhost works.
i couldn't use localhost  on my url , i get an error.
one of the solution is to use my ip (in the local domain 10.0.0.5),
but i get access error HTTP/1.1 400 Bad Request 
i follow this link
http://stackoverflow.com/questions/5433786/configure-iis-express-for-external-access-to-vs2010-project/5438322#5438322

and this
http://stackoverflow.com/questions/7877523/how-to-allow-iisexpress-to-listen-internet

and i decided to change the next file  (win 7)
%userprofile%\documents\iisexpress\config\applicationhost.config

i change the next line - under my project (replace localhost with 10.0.0.5)
 <binding protocol="https" bindingInformation="*:44300:10.0.0.5" />

and my android managed to consume the service 

enjoy
