Презентация с семинара "LINQ'остроительство и SharePoint"

1. SharePoint, LINQ иOpen Data Protocol Vitaly Baum Senior SharePoint Developer @ Conteq Активный участник групп разработчиков в Санкт-Петербурге и Москве, подкастер и блоггер http://butaji.ru

2. План выступления LINQ to SharePoint 2010 Open Data Protocol

3. LINQ to SharePoint

4. Преимущества LINQ Строгая типизация Запросы к реляционным данным в строго-типизированной форме Компилятор проверит ошибки в запросах IntelliSense Унифицированный путь получения данных из любого источника

5. LINQ to SharePoint SPMetal Генерирует DataContext SPMetal /web:http://ContosoServer/Marketing /code:MarketingSite.cs

6. LINQ to SharePoint Недостатки Преобразуется в CAML Не все операторы реализованы Двухэтапные запросы Аггрегирующие запросы SPSiteDataQuery

7. Mapping internal partial class OrganisationSiteDataContext : Microsoft.SharePoint.Linq.DataContext{} [ContentType(Name = "Employee")] public partial class Employee { [Column(Name="ID", IsId=true, ReadOnly=true, FieldType="Counter")] public int Id {get; set;} }

8. ICostumMapping public partial class Project : ICustomMapping { [CustomMapping(Columns = new String[] { «Due_x0020_Date», «IsCancelled» })] public void MapFrom(object listItem) { this.DueDate= ((SPListItem)listItem)[“Due_x0020_Date”]; this.IsCancelled = ((SPListItem)listItem)[“IsCancelled”]; } public void MapTo(object listItem) { ((SPListItem)listItem)[“Due_x0020_Date”] = this.DueDate; ((SPListItem)listItem)[“IsCancelled”] = this.IsCancelled; } public void Resolve(RefreshMode mode, object originalListItem, object databaseObject) { } }

9. SPMetal ImtechSPMetalDefinition Extension

10. LINQ to SharePoint Демо
