2. Verify that your machine where powershell is available , latest version of .Net Framework is installed.

3.  Verify that in powershell you have "Send-MailMessage" available .

(in powershell window type  :---- Get-Command Send-MailMessage )

4.   Export your gmail/ any other email account contacts as csv  . Say it has name of contact column as "name"  and email as "email"

Possible Reasons / Solutions : 

1.  uninstall  FluentNHibernate  ,  NHibernate ,  Iesi.Collections . install FluentNHibernate   , it will automatically install correct version of NHibernate and Iesi.Collections required . Check if your app.config / web.config have wrong versions of dll's referred , may be under runtime .

2. Generally  in nhiberante mappings you define id field for the table like :

Id(x => x.somecolumn).GeneratedBy.Assigned().Not.Nullable();   // reflection to determine column name so its ok to skip .column here

//or

Id(x => x.SomeColumn).GeneratedBy.Assigned().Column("\"SomeColumn\"").Not.Nullable();

//In the above two cases , your own code is responsible to maintain unique id . So used //Assigned

//or

Id(x => x.SomeColumn).GeneratedBy.Assigned().Column("some_column").Not.Nullable();

//snake_case  so ok to skip  \"

//or

Id(x => x.Id).GeneratedBy.Sequence("\"My_Id_seq\"").Column("\"Id\"");

// in the above case you have a Sequence to generate unique ids / primary key  in db

or else

The idea is after GeneratedBy  make sure you have chosen right option as per your table  e.g.

• Assigned :   lets the application to assign an identifier to the object before Save()  is called. ( with or without Params configuration )


• Foreign  :  uses the identifier of another associated object. Usually used in conjunction  with a one-to-one primary key association.


• HiLo :   uses a hi/lo algorithm to efficiently generate identifiers of any integral type, given a table and column (by default hibernate_unique_key and next_hi respectively) as a source of hi values. The hi/lo algorithm generates identifiers that are unique only for a particular database. Do not use this generator with a user-supplied connection. requires a "special" database table to hold the next available "hi" value


• Identity  :   supports identity columns in DB2, MySQL, MS SQL Server and Sybase. The identifier returned by the database is converted to the property type using Convert.ChangeType. Any integral property type is thus supported.


• Increment :   generates identifiers of any integral type that are unique only when no other process is inserting data into the same table. Do not use in a cluster.


• Sequence :  uses a sequence in DB2, PostgreSQL, Oracle or a generator in Firebird. The identifier returned by the database is converted to the property type using Convert.ChangeType. Any integral property type is thus supported.

See FluentNHibernate.Mapping.IdentityGenerationStrategyBuilder  for more possible options.

This is what happened when I changed my password for Git Repository ( with Visual Studio Tools for Git http://visualstudiogallery.msdn.microsoft.com/abafc7d6-dcaa-40f4-8a5e-d6724bdb980c )

Solution :

1. Close all Visual Studio instances


2. Go to Control Panel > Credential Manager


3. Delete the entries related to your repository.(Link )


4. Now whenever you will try to connect to server using Visual studio , it will ask for credentials and recreate these entries in Credential manager.

Should I Pay money to Google Adsense ? Prove using Powershell

Last week I  finalized a new hosting plan . It offers me $100 worth of code for Google adsense and similar programs.  This was the 1st time I saw Google adsense with angle of an advertiser . (Probably when I last time renewed my hosting  also , I got these codes , but never used it . Was not even aware of what it is at that moment )

1st question which comes to me , do they make us fool !!! Does this $ 100 really worth something .  After all brainstorming  my conclusion is : if you are selling a product , invest only in a program  which charges you as per actual product sale .  Never invest in Google adsense and similar programs , who just take responsibility of taking user to your door on web , if they don't promise / convert in to actual sale , don't pay them .

Well, I am not saying something in air . I have valid points to prove it , if you agree with below mentioned , you must admit what I said above :

Muliple Get, Put, Post, Delete under Web API calls to same Controller from Angular JS

In the example mentioned below , you could define multiple PUT to same Web API controller
