/// <summary>
/// Calculates the credit score based on the SSN and name.
/// </summary>
/// <remarks>
/// This depends on a custom entity called Loan Application and customizations to Contact.
///
/// Loan Application requires the following properties:
/// <list>
/// <item>Schema Name: new_loanapplication</item>
/// <item>Attribute: new_loanapplicationid as the primary key</item>
/// <item>Attribute: new_creditscore of type int with min of 0 and max of 1000 (if it is to be updated)</item>
/// <item>Attribute: new_loanamount of type money with default min/max</item>
/// <item>Customize the form to include the attribute new_loanapplicantid</item>
/// </list>
///
/// Contact Requires the following customizations
/// <list>
/// <item>Attribute: new_ssn as nvarchar with max length of 15</item>
/// <item>One-To-Many Relationship with these properties:
/// <list>
/// <item>Relationship Definition Schema Name: new_loanapplicant</item>
/// <item>Relationship Definition Related Entity Name: Loan Application</item>
/// <item>Relationship Atttribute Schema Name: new_loanapplicantid</item>
/// <item>Relationship Behavior Type: Referential</item>
/// </list>
/// </item>
/// </list>
///
/// The activity takes, as input, a EntityReference to the Loan Application and a boolean indicating whether new_creditscore should be updated to the credit score.
/// </remarks>
/// <exception cref=">ArgumentNullException">Thrown when LoanApplication is null</exception>
/// <exception cref=">ArgumentException">Thrown when LoanApplication is not a EntityReference to a LoanApplication entity</exception>
