Dynamics 365 (CRM) Get Primary Field name and Primary Id field name of an given entity

Hello World,

When you get to a scenario where you are writing a generic logic to be shared in few plugin steps and you are not sure about the entity you will get to process, but you need to know the schema names of primary field and id of the given entity. So pathetic right :)

Here is my solution. Use metadata.

using Microsoft.Xrm.Sdk;
using Microsoft.Xrm.Sdk.Messages;
using Microsoft.Xrm.Sdk.Metadata;
using Microsoft.Xrm.Sdk.Query;


//Create RetrieveEntityRequest
  RetrieveEntityRequest retrievesEntityRequest = new RetrieveEntityRequest
    {
         EntityFilters = EntityFilters.Entity,
         LogicalName = primaryEntityName
    };

//Execute Request
  RetrieveEntityResponse retrieveEntityResponse = (RetrieveEntityResponse) service.Execute(retrievesEntityRequest);
  var idFieldName = retrieveEntityResponse.EntityMetadata.PrimaryIdAttribute;

  var primaryFieldName = retrieveEntityResponse.EntityMetadata.PrimaryNameAttribute;

Need to discuss about getting entity relationships too. Next post for sure.
