What is the difference between NHibernate and fluent NHibernate?

What is the difference between NHibernate and fluent NHibernate?

Fluent NHibernate offers an alternative to NHibernate’s standard XML mapping files. Rather than writing XML documents, you write mappings in strongly typed C# code. This allows for easy refactoring, improved readability and more concise code.

How to use Fluent NHibernate?

Basic Setup of Fluent NHibernate

1. Step 1: Create the Database and Table.
2. Step 2: Create a Console App (.
3. Step 3: Create Your Entities/Classes.
4. Step 4: Create the Mapping (Entities to DB Tables)
5. Step 5: Create the NHibernate Configuration.
6. Step 6: Read and Write to the DB Table.

Is NHibernate better than Entity Framework?

Entity Framework Core uses fluent (code-based) configuration and fluent or attribute-based mappings. Custom conventions are very powerful in NHibernate, EF Core still doesn’t have them, and this is something that NHibernate is better at, right now. Both of them need mappings, in any form.

Why we use NHibernate in. net?

NHibernate is Designed to serve as a persistence layer exclusively for the . Net framework based on Object-Relational Mapping Technique. A tool that creates a “virtual representation” of database objects within the code. Used to solve the problem of impedance mismatch between Class and relational databases and tables.

Is NHibernate free?

NHibernate is an object–relational mapping (ORM) solution for the Microsoft . NET platform. NHibernate is free and open-source software that is distributed under the GNU Lesser General Public License. NHibernate is a port of Hibernate.

What is the difference between NHibernate and Entity Framework?

Entity framework used code-based (fluent) configuration or attribute-based (fluent) mapping. NHibernate uses XML and Fluent configuration and mapping. NHibernate Attributes is used to provide attribute mapping. NHibernate provides custom conventions and EF doesn’t provide them.

How do I use NHibernate Profiler?

The method of doing so is:

1. Add a reference to the following dll’s: HibernatingRhinos.
2. To log to a file that can be loaded later into the NHibernate Profiler, create a log4net.
3. In the application startup, call: log4net.Config.XmlConfigurator.Configure(new FileInfo(“/path/to/log4net.config”));

What are POCO classes?

POCO Entities (Plain Old CLR Object) A POCO entity is a class that doesn’t depend on any framework-specific base class. It is like any other normal . NET CLR class, which is why it is called “Plain Old CLR Objects”. POCO entities are supported in both EF 6 and EF Core.

How do I get SQL query from NHibernate?

Capture NHibernate generated SQL Query real-time / at runtime

1. Create a class to store the NHibernate generated SQL Query.
2. Create an Interceptor class that implements the IInterceptor interface.
3. Implement the OnPrepareStatement method and set the NHibernate generated SQL Query created in step 1.

What are CLR classes?

CLR is Common Language Runtime not a class. The Common Language Runtime (CLR) is the virtual machine component of Microsoft’s . NET framework and is responsible for managing the execution of . NET programs.

What POCO means?

plain old class object
In software engineering, a plain old CLR object, or plain old class object (POCO) is a simple object created in the . NET Common Language Runtime (CLR) that is unencumbered by inheritance or attributes. In essence, a POCO does not have any dependency on an external framework.

How is fluent NHibernate used in Visual Studio?

Fluent NHibernate uses the fluent pattern and it is based on conventions to create the mappings and it gives you the power of the visual studio tools (such as intellisense) to improve the way you map your entities. Add the reference of the Fluent NHibernate from Nuget on your project and add a class CustomerMap.cs:

What do you need to know about fluentnhibernate?

Provides NHibernate persistance support for a Sharp Architecture application, providing NHibernate session managment and initialisation, and implementations of core SharpArch data access interfaces. Contains core Ucommerce assemblies alongside all dependencies.

Which is the base class for mapping in NHibernate?

The CustomerMap class inhirits from ClassMap that is the base class for mapping and contains all methods necessary to create the map of your T entity. The method Table define the table name you are mapping.
