Early Binding v/s Late Binding in Dynamics 365 Custom code

While writing custom code using dot net for dynamics 365 CE we can write code either using early-binding or late binding. There are many advantages and disadvantages in both lets look both and decide which one you can use.

Late Binding

In late binding we do not need to do entity class generation process. The entity, column names are validated in runtime. Its bit faster in performance. The below image gives you advantages and dis-advantages of late binding with example.

Early Binding

In Early binding we do need to do entity class generation process. The entity, column names are validated in compile time. Its bit slower in performance. The below image gives you advantages and dis-advantages of late binding with example.

Now which one you can use. Use below image differentiation to decide.

Watch the video below to learn how to generate early bind classes using SVCUtil tool and also how to generate selected entity class instead of all entity.

Generate code for all entities

CrmSvcUtil.exe /url:https://newdevsoft.api.crm.dynamics.com/XRMServices/2011/Organization.svc /out:C:\Users\Admin\Documents\EarlyBound.cs /username:”sanjay@softchief21.onmicrosoft.com” /password:”pass” /namespace:earlybound /serviceContextName:ServiceContext

For Selected Entities

CrmSvcUtil.exe /url:https://newdevsoft.api.crm.dynamics.com/XRMServices/2011/Organization.svc /out:C:\Users\Admin\Documents\EarlyBoundfilter.cs /username:”sanjay@softchief21.onmicrosoft.com” /password:”Dream@123″   /namespace:earlybound /codewriterfilter:SvcUtilFilter.CodeWriterFilter,SvcUtilFilter
