NHibernate Fluent Configuration

In this post you saw how use NH2.1.0 configuration in different ways. This post is about the fluent-interface based configuration of NH3.0.0 (well… perhaps it is not the final implementation but only closer to it). Another programmatic configuration based on lambda usage is coming.

Minimal

var cfg = new Configuration();
cfg.SessionFactory()
   .Proxy.Through<ByteCode.LinFu.ProxyFactoryFactory>()
   .Integrate
       .Using<MsSql2005Dialect>()
       .Connected
           .Using(new SqlConnectionStringBuilder
                      {
                          DataSource = "(local)",
                          InitialCatalog = "nhibernate",
                          IntegratedSecurity = true
                      });

To configure the connection-string I’m using the DbConnectionStringBuilder of a specific DataProvider (in this case System.Data.SqlClient.SqlConnectionStringBuilder; your DataProvider should have its own implementation).

Pretty Complete

var cfg = new Configuration();
cfg.SessionFactory().Named("SomeName")
   .Caching
       .Through<HashtableCacheProvider>()
       .PrefixingRegionsWith("xyz")
       .Queries
           .Through<StandardQueryCache>()
       .UsingMinimalPuts()
       .WithDefaultExpiration(15)
   .GeneratingCollections
       .Through<DefaultCollectionTypeFactory>()
   .Proxy
       .DisableValidation()
       .Through<ProxyFactoryFactory>()
   .ParsingHqlThrough<ClassicQueryTranslatorFactory>()
   .Mapping
       .UsingDefaultCatalog("MyCatalog")
       .UsingDefaultSchema("MySche")
   .Integrate
       .Using<MsSql2000Dialect>()
       .AutoQuoteKeywords()
       .BatchingQueries
           .Through<SqlClientBatchingBatcherFactory>()
           .Each(15)
       .Connected
           .Through<DebugConnectionProvider>()
           .By<SqlClientDriver>()
           .Releasing(ConnectionReleaseMode.AfterTransaction)
           .With(IsolationLevel.ReadCommitted)
           .Using("The connection string")
       .CreateCommands
           .AutoCommentingSql()
           .ConvertingExceptionsThrough<SQLStateConverter>()
           .Preparing()
           .WithTimeout(10)
           .WithMaximumDepthOfOuterJoinFetching(11)
           .WithHqlToSqlSubstitutions("true 1, false 0, yes 'Y', no 'N'")
       .Schema
           .Validating()
;
