Public methodCreatePropertyGroupFinds or creates a property group with the given information.
Public methodEquals(Object)Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public methodGetEnumeratorRetrieves the enumeration interface for the collection.
Public methodGetHashCodeServes as a hash function for a particular type. (Inherited from Object.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Public methodGroupFinds the property group with the given name.
Protected methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Public methodToStringReturns a string that represents the current object. (Inherited from Object.)

Public Extension MethodAsParallelEnables parallelization of a query. (Defined by ParallelEnumerable.)
Public Extension MethodAsQueryableConverts an IEnumerable to an IQueryable. (Defined by Queryable.)
Public Extension MethodCast<TResult>Converts the elements of an IEnumerable to the specified type. (Defined by Enumerable.)
Public Extension MethodOfType<TResult>Filters the elements of an IEnumerable based on a specified type. (Defined by Enumerable.)

The following sample shows how to use SharedPropertyGroupManager to create and mange shared properties.

using System;
using System.EnterpriseServices;
using System.Reflection;

[assembly: ApplicationName("ReceiptNumberGenerator")] 
[assembly: ApplicationActivation(ActivationOption.Library)] 

public class ReceiptNumberGeneratorClass
    // Generates a new receipt number based on the receipt number
    // stored by the Shared Property Manager (SPM)
    public int GetNextReceiptNumber() 
        bool groupExists,propertyExists;
        int nextReceiptNumber = 0;
        PropertyLockMode lockMode = PropertyLockMode.SetGet;
        PropertyReleaseMode releaseMode = PropertyReleaseMode.Standard;

        // Create a shared property group manager.
        SharedPropertyGroupManager groupManager = new SharedPropertyGroupManager();
        // Create a shared property group.
        SharedPropertyGroup group = groupManager.CreatePropertyGroup("Receipts",
                                   ref lockMode, ref releaseMode, out groupExists);
        // Create a shared property.
        SharedProperty ReceiptNumber;
        ReceiptNumber = group.CreateProperty("ReceiptNumber",out propertyExists);
        // Retrieve the value from shared property, and increment the shared 
        // property value.
        nextReceiptNumber = (int) ReceiptNumber.Value;
        ReceiptNumber.Value = nextReceiptNumber + 1;
        // Return nextReceiptNumber
        return nextReceiptNumber;
