What is early binding and late binding? How is it used in CRM?

Introduction: 

     In this article, we will explore the concepts of early binding and late binding and their significance in the context of CRM (Customer Relationship Management). Both approaches have their advantages and use cases, which can impact the development and performance of your CRM system. So, let's dive in and understand how early and late binding are utilized in CRM.

Early Binding: 

   Early binding refers to the process of resolving object types and method calls during compile-time. In CRM, early binding involves creating and using strongly-typed classes for CRM entities. These classes are generated from the CRM metadata, and their properties and methods directly correspond to the CRM entity attributes and actions.

Benefits of Early Binding in CRM: 

a. Type Safety: Early binding provides compile-time type checking, reducing the likelihood of runtime errors related to data types and method calls. 

b. IntelliSense Support: Developers can leverage IntelliSense to explore available attributes and methods for CRM entities, improving productivity and code accuracy. 

c. Improved Performance: Early binding can be more efficient as the compiler already knows the types at compile-time, reducing the overhead of type resolution at runtime. 

d. Easier Debugging: Compile-time errors are easier to debug compared to runtime errors, resulting in a smoother development process.

 var account = new Account();
// set attribute values
    // string primary name
    account.Name = "Contoso";
    // Boolean (Two option)
    account.CreditOnHold = false;
    // DateTime
    account.LastOnHoldTime = new DateTime(2017, 1, 1);
    // Double
    account.Address1_Latitude = 47.642311;
    account.Address1_Longitude = -122.136841;
    // Int
    account.NumberOfEmployees = 500;
    // Money
    account.Revenue = new Money(new decimal(5000000.00));
    // Picklist (Option set)
    account.AccountCategoryCode = new OptionSetValue(1); //Preferred customer

//Create the account
Guid accountid = svc.Create(account);

Late Binding: 

Late binding, on the other hand, occurs during runtime, where objects and method calls are resolved dynamically using reflection or other runtime mechanisms. In CRM, late binding is achieved using the generic Entity class and attribute names represented as strings.

Benefits of Late Binding in CRM: 

a. Flexibility: Late binding allows dynamic handling of entities, making it easier to work with multiple CRM entities without explicitly defining their types at compile-time.

 b. Reduced Dependency: Late binding can help minimize dependencies on specific CRM entity classes, allowing for more adaptable and generic code. 

c. Runtime Entity Resolution: This approach enables the creation and modification of CRM entities that are not known at compile-time. 

d. Seamless Upgrades: Late binding can be advantageous when dealing with CRM solutions that may change or get upgraded over time, as it adapts dynamically to new entities.

//Use Entity class specifying the entity logical name
var account = new Entity("account");

// set attribute values
    // string primary name
    account["name"] = "Contoso";            
    // Boolean (Two option)
    account["creditonhold"] = false;
    // DateTime
    account["lastonholdtime"] = new DateTime(2017, 1, 1);
    // Double
    account["address1_latitude"] = 47.642311;
    account["address1_longitude"] = -122.136841;
    // Int
    account["numberofemployees"] = 500;
    // Money
    account["revenue"] = new Money(new decimal(5000000.00));
    // Picklist (Option set)
    account["accountcategorycode"] = new OptionSetValue(1); //Preferred customer
                
//Create the account
Guid accountid = svc.Create(account);

Implementation in CRM: 

a. Early Binding: 

    To use early binding in CRM, developers generate strongly-typed classes using the CrmSvcUtil tool, which creates classes based on the CRM metadata. These classes can then be included in the CRM solution, and developers can easily access CRM entities and perform operations using these classes.

b. Late Binding: 

For late binding in CRM, developers can utilize the generic Entity class provided by the CRM SDK. This class allows dynamic handling of CRM entities by specifying attribute names as strings during runtime, enabling entity creation, retrieval, and manipulation without the need for pre-generated classes.

Conclusion: 

In summary, both early binding and late binding have their merits and are utilized differently in CRM development. Early binding offers improved performance, type safety, and IntelliSense support, making it ideal for scenarios with known entities and a desire for robustness. On the other hand, late binding provides flexibility and adaptability, making it suitable for situations where entities might change or are not known in advance.

Selecting the appropriate binding approach depends on your CRM project requirements and development preferences. We hope this article has clarified the concepts and uses of early and late binding in CRM, empowering you to make informed decisions for your CRM implementation.
