i think the error its not accurate, u can check

in this cod i cant serialaize object: string jsonString = JsonSerializer.Serialize(Obj); the error is :
No overload for method 'Serialize' takes 1 arguments

im verry sorry i ask again i send the correct checksum but in server side get 0

how can i check content of soap requset from xamarin to web service online?

i do not have access to web service code,i can only ask the number of checksum and compare with my check sum in app side code

i created sample list only for my test

My connection to the database is only pre-defined from the procedure

yes its my qustion but this simulate data to solve my problem

i've done this before ,but dosent fire sqldependency
i useed 2 query first one is simple for check notify and second one for display some message but dosent work on display real time alarm only show after refresh page

System.Data.Entity.Infrastructure.UnintentionalCodeFirstException: 'The context is being used in Code First mode with code that was generated from an EDMX file for either Database First or Model First development. This will not work correctly. To fix this problem do not remove the line of code that throws this exception. If you wish to use Database First or Model First, then make sure that the Entity Framework connection string is included in the app.config or web.config of the start-up project. If you are creating your own DbConnection, then make sure that it is an EntityConnection and not some other type of DbConnection, and that you pass it to one of the base DbContext constructors that take a DbConnection. To learn more about Code First, Database First, and Model First see the Entity Framework documentation here: http://go.microsoft.com/fwlink/?LinkId=394715'

why, and which way is better?
