ExtensibleDbContext Class

Namespace: PTS.EntityLayer.Extensibility

Assembly: PTS.EntityLayer.Extensibility.dll

Constructors

ExtensibleDbContext(DbContextOptions)

Initializes a new instance of the ExtensibleDbContext class.

Declaration

public ExtensibleDbContext(DbContextOptions options)

Parameters

Type	Name	Description
Microsoft.EntityFrameworkCore.DbContextOptions	options	The options for this context.

Methods

Dispose()

Releases the allocated resources for this context and its entity service provider.

Declaration

public override void Dispose()

Overrides

Microsoft.EntityFrameworkCore.DbContext.Dispose()

GetEntityService<TService>()

Get entity service of specified generic type.

Declaration

public TService GetEntityService<TService>()

Returns

Type	Description
TService	A service of specified generic type.

Type Parameters

Name	Description
TService	The type of service to get.

Exceptions

Type	Condition
System.MissingMemberException	Thrown if the specified service was not found.

OnConfiguring(DbContextOptionsBuilder)

Override this method to configure the database (and other options) to be used for this context. This method is called for each instance of the context that is created. The base implementation does nothing.

In situations where an instance of Microsoft.EntityFrameworkCore.DbContextOptions may or may not have been passed to the constructor, you can use Microsoft.EntityFrameworkCore.DbContextOptionsBuilder.IsConfigured to determine if the options have already been set, and skip some or all of the logic in Microsoft.EntityFrameworkCore.DbContext.OnConfiguring(Microsoft.EntityFrameworkCore.DbContextOptionsBuilder).

Declaration

protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder)

Parameters

Type	Name	Description
Microsoft.EntityFrameworkCore.DbContextOptionsBuilder	optionsBuilder	A builder used to create or modify options for this context. Databases (and other extensions) typically define extension methods on this object that allow you to configure the context.

Overrides

Microsoft.EntityFrameworkCore.DbContext.OnConfiguring(Microsoft.EntityFrameworkCore.DbContextOptionsBuilder)

OnEntityModelCreated(ModelBuilder)

Override this method to further configure the model that was discovered by convention from the entity types exposed in properties on your derived context. The resulting model may be cached and re-used for subsequent instances of your derived context.

Declaration

protected virtual void OnEntityModelCreated(ModelBuilder modelBuilder)

Parameters

Type	Name	Description
Microsoft.EntityFrameworkCore.ModelBuilder	modelBuilder	The builder being used to construct the model for this context. Databases (and other extensions) typically define extension methods on this object that allow you to configure aspects of the model that are specific to a given database.

Remarks

If a model is explicitly set on the options for this context (via Microsoft.EntityFrameworkCore.DbContextOptionsBuilder.UseModel(Microsoft.EntityFrameworkCore.Metadata.IModel)) then this method will not be run.

OnModelCreating(ModelBuilder)

Configures the model that was discovered by convention from the entity types exposed in properties in current context type.

Declaration

protected override sealed void OnModelCreating(ModelBuilder modelBuilder)

Parameters

Type	Name	Description
Microsoft.EntityFrameworkCore.ModelBuilder	modelBuilder	The builder being used to construct the model for this context. Databases (and other extensions) typically define extension methods on this object that allow you to configure aspects of the model that are specific to a given database.

Overrides

Microsoft.EntityFrameworkCore.DbContext.OnModelCreating(Microsoft.EntityFrameworkCore.ModelBuilder)

Remarks

If a model is explicitly set on the options for this context (via Microsoft.EntityFrameworkCore.DbContextOptionsBuilder.UseModel(Microsoft.EntityFrameworkCore.Metadata.IModel)) then this method will not be run.
