|
ChangeConflictException | Thrown when an update fails because database values have been updated since the client last read them. |
|
ChangeSet | Provides a container to hold changes. |
|
CompiledQuery | Provides for compilation and caching of queries for reuse. |
|
DataContext | The data context is an object representing the database, a proxy, containing Table objects that represent the tables in the database. |
|
DataLoadOptions | Provides for immediate loading and filtering of related data. |
|
DBConvert | Infrastructure. Used internally to convert one type to another. |
|
DuplicateKeyException | Thrown when an attempt is made to add an object to the identity cache by using a key that is already being used. |

|
Link<T> | Used to enable deferred loading of individual properties (similar to EntityRef<TEntity>). |
|
ModifiedMemberInfo | Holds values of members that have been modified in LINQ to SQL applications. |
| Interface | Description | |
|---|---|---|
|
ITable | Used for weakly typed query scenarios. |
|

| Enumeration | Description | |
|---|---|---|
|
ChangeAction | Describes the type of change the entity will undergo when changes are submitted to the database. |
