Dynamics CRM 2016 – Custom plugin development using CRM Development Tool Kit

This time we are going through a process of building a custom plug-in for Microsoft Dynamics CRM and its deployment on development server.  I assume that you already downloaded and setup Development Tool Kit. And make sure CRM templates are imported in Visual Studio.

Start with creating a solution using Dynamics CRM. Navigate to Settings >> Customization >> Solution. Create a new Solution “AccountPlugin” and choose any name based on project and company requirement. In case, you are going to develop plugin for any existing solution skip this steps.

PluginSolution

Save CRM solution and publish.

PublishSolution_2

In Visual Studio, Create new project using Dynamics CRM 2013 Package template. If templates are not available, make sure that you already imported development tool kit templates in Visual Studio.

Dynamics CRM package is selected instead of Dynamics CRM 2013 plugin because it will make our process easy for plugin registration and deployment using tool kit.

ConnectionTOCRM_3

You will be asked to connect CRM live before Visual Studio setup package solution. CRM connection screen pops up. You can also open it from Tool >> CRM connection.

Connection To CRM

Fill out required details and connect development Dynamics CRM server.

URL: CRM URL.

User Name: Domain Administrator

Password:   Domain Administrator Password

Browse all organizations and select appropriate organization and solution to hook plugin.

ConnectionTOCRM_3

After a successful connection with CRM server, CRM package solution will be created in Visual Studio. Next step is to add a CRM plugin library project in solution. More plug-in projects can be added in one solution.

add plugin solution

Now Visual Studio solution is set up and ready for plugin development. Some important file and DLLs are added in projects which are required. Let me elaborate important of these files.

RegisterFile.crmregistration is xml file contains details of all added plugins and workflows and register those in Dynamics CRM when package is deployed. Its auto created file using CRM Development Tool Kit.

Microsoft.Crm.Sdk.Proxy and Microsoft.Xrm.Sdk are two very important DLLs referenced in plugin project. These DLLs contain core classes of Microsoft dynamics CRM which are used for plugin operations.

Next step is to create strong name key for plugin project. Right click on project and select properties and create new Strong Name key (SNK). SNK is system oriented and when you move this development code on another machine, SNK needs to create again.

SNLKey_11

Open CRM explorer from View>>CRM explorer and expend entities. Right click on Account entity and select create plugin. It’s popping up Create Plug-in window.

Let’s go through Create Plug-in form attributes. First one “Project” is default set to “AccountPlugin” as it’s related to a single plugin project, in case we have more than one plugin projects. It will be enabled for selection.

Next is “Primary entity” is about to entity for which plugin is being created and it “Account” entity.

Next one is “Message” is about to CRM action, it’s associated with.

AccountActionMessage_7

Next important attribute is “Pipeline Stage” and it’s specifying execution time of plugin. In this example, we created “PostAccountcreate” plugin. So Pipeline Stage is to determine on which stage of “PostAccountCreate”, this plug-in will fire.

PluginPipelineStage_8

Next one is “Class” to specify class name for plug-in. Next important attribute is “Execution order” to specify order of plugin execution. In case of many plugins are associated with an action stage, it will be used to determine the execution order of this plug-in. Click Ok and plugin will be created.

After successful creation of “AccountPlugin”. Open “RegisterFile.crmregister” file and a new code line is added in xml for created “AccountPlugin” plugin.

Account Plugin Registration_9

“PostAccountCreate” class is added in plug-in project, where custom code will be written for operations required under this plugin. “ExecutePostAccountCreate” method is responsible for plugin operations.

Sample code lines for update Account entity Name attribute:

protected void ExecutePostAccountCreate(LocalPluginContext localContext)

{

if (localContext == null)

{

throw new ArgumentNullException(“localContext”);

}

 

// TODO: Implement your custom Plug-in business logic.

IPluginExecutionContext Context = localContext.PluginExecutionContext;

IOrganizationService service = localContext.OrganizationService;

ITracingService trace = localContext.TracingService;

 

 

Entity entity = null;

EntityReference parentCustomerIdAttribRef = null;

 

// If we have a target

if (Context.InputParameters.Contains(“Target”) && Context.InputParameters[“Target”] is Entity)

{

// Obtain the target entity

entity = (Entity)Context.InputParameters[“Target”];

 

// Only perform this code if this is a create

if (Context.MessageName != “Update”) { return; }

 

// Only perform this code for a certain entity

if (Context.PrimaryEntityName != “account”) { return; }

 

// Only perform this code if this column is included in the collection of attributes

 

else { return; }

}

else { return; }

try

{

 

// update entity attribute with attribute value

entity.Attributes[“name”] = “John”;

 

//Update account entity

service.Update(entity);

}

}

catch (FaultException<OrganizationServiceFault> e)

{ trace.Trace(string.Format(“Exception: {0}”, e.ToString())); }

catch (Exception ex)

{ trace.Trace(string.Format(“Exception: {0}”, ex.ToString())); }

}

}

Sample code lines use to update Account attribute name value as John. So after an account is created in CRM, account name attribute is updated as “john”.

At the end build project and right click on package and select deploy.
