plugin crm dynamics 2015

Question

I'm trying to create a simple plugin and register it to my MSDN CRM - solution. I have Microsoft CRM SDK and the Microsoft Solution Manager to help me with this.

The CRM solution manager provides a base plugin for this when I create a project, but lacks any logic (ofc).

Where in this base plugins Execution method below do I put the logic? If possible?

 /// <summary>
    /// Executes the plug-in.
    /// </summary>
    /// <param name="serviceProvider">The service provider.</param>
    /// <remarks>
    /// For improved performance, Microsoft Dynamics CRM caches plug-in instances. 
    /// The plug-in's Execute method should be written to be stateless as the constructor 
    /// is not called for every invocation of the plug-in. Also, multiple system threads 
    /// could execute the plug-in at the same time. All per invocation state information 
    /// is stored in the context. This means that you should not use global variables in plug-ins.
    /// </remarks>
    public void Execute(IServiceProvider serviceProvider)
    {
        if (serviceProvider == null)
        {
            throw new ArgumentNullException("serviceProvider");
        }

        // Construct the Local plug-in context.
        LocalPluginContext localcontext = new LocalPluginContext(serviceProvider);

        localcontext.Trace(string.Format(CultureInfo.InvariantCulture, "Entered {0}.Execute()", this.ChildClassName));

        try
        {
            // Iterate over all of the expected registered events to ensure that the plugin
            // has been invoked by an expected event
            // For any given plug-in event at an instance in time, we would expect at most 1 result to match.
            Action<LocalPluginContext> entityAction =
                (from a in this.RegisteredEvents
                 where (
                 a.Item1 == localcontext.PluginExecutionContext.Stage &&
                 a.Item2 == localcontext.PluginExecutionContext.MessageName &&
                 (string.IsNullOrWhiteSpace(a.Item3) ? true : a.Item3 == localcontext.PluginExecutionContext.PrimaryEntityName)
                 )
                 select a.Item4).FirstOrDefault();

            if (entityAction != null)
            {
                localcontext.Trace(string.Format(
                    CultureInfo.InvariantCulture,
                    "{0} is firing for Entity: {1}, Message: {2}",
                    this.ChildClassName,
                    localcontext.PluginExecutionContext.PrimaryEntityName,
                    localcontext.PluginExecutionContext.MessageName));

                entityAction.Invoke(localcontext);

                // now exit - if the derived plug-in has incorrectly registered overlapping event registrations,
                // guard against multiple executions.
                return;
            }
        }
        catch (FaultException<OrganizationServiceFault> e)
        {
            localcontext.Trace(string.Format(CultureInfo.InvariantCulture, "Exception: {0}", e.ToString()));

            // Handle the exception.
            throw;
        }
        finally
        {
            localcontext.Trace(string.Format(CultureInfo.InvariantCulture, "Exiting {0}.Execute()", this.ChildClassName));
        }
    }

You can strip the code to only this:

public void Execute(IServiceProvider serviceProvider)
{
    LocalPluginContext localcontext = new LocalPluginContext(serviceProvider);

    localcontext.Trace(string.Format(CultureInfo.InvariantCulture, "Entered {0}.Execute()", this.ChildClassName));

    try
    {

    }
    catch (FaultException<OrganizationServiceFault> e)
    {
        localcontext.Trace(string.Format(CultureInfo.InvariantCulture, "Exception: {0}", e.ToString()));

        // Handle the exception.
        throw;
    }
    finally
    {
        localcontext.Trace(string.Format(CultureInfo.InvariantCulture, "Exiting {0}.Execute()", this.ChildClassName));
    }
}

and add your code to the try block.

The IServiceProvider provides you the IPluginExecutionContext and IOrganizationServiceFactory instances you need to a. get the context your plugin is executing in and b. get access to the organization service interface.
