- Added additional convenience methods to the `MaterializationContext` to retreive loading table info for models mapped via annotations (ModelType; vs only ordinal or string name).
- Added support to cancel the materialization process via new `MaterializationContext.CancelMaterializationProcess()` method; allows passive cancelling without the need to throw an exception to safely stop the process.
- Fixed small configuration initialization bugs when manually setting the `IsFullTextIndexHandlingEnabled` flag.
- Fixed small bug where default configuration was not being used as the fallback.

Prior Relese Notes:
- Improve configuration of Timeouts and add support for Default DB Schema Loader timeout setting.
- v2.0 provides a simplified and easier to access API as Extension Methods of the SqlTransaction class; this is a breaking change for Sql Bulk Insert/Update/etc, but shoudl be easy to migrate to!
- v2.0 release also includes the NEW MaterializeData Helpers to make it significantly easier to implement highly efficient loading and publishing of materialized data via Sql Server much easier via an easy C# API.
- The concept of Materializing data is to enable easy aysnc (background) bulk loading of data with, no impact to Live tables, until the data is switched out extremely quickly accomplishing a refresh of Live data in milliseconds.
- The all new APIs include (but not limited to): ExecuteMaterializeDataProcessAsync(), ClearTablesAsync(), CloneTablesAsync(), DropTablesAsync(), RemoveFullTextIndexAsync(), & GetTableSchemaDefinition().
- v2.0 Now includes support for Model mapping attributes for Class and Properties with support for RepoDb ([Map]), Linq2Sql ([Table]/[Column]), and Dapper ([Table]/[Column]); and others that use the same Attribute notations.
- Add improved reliability now with use of LazyCacheHelpers for the in-memory caching of DB Schema Loaders; this now fixes an edge case issue where an Exception could be cached and re-initialization was never attempted.
- Added support to now clear the DB Schema cache via SqlBulkHelpersSchemaLoaderCache.ClearCache() to enable dynamic re-initialization when needed (vs applicaiton restart).
- Add improved support for use of SqlBulkHelpersDbSchemaCache with new SqlConnection factory func to greatly simplifying its use with optimized deferral of Sql Connection creation (if and only when needed) without having to implement the full Interface.
- Merge PR to enable support Fully Qualified Table Names - Thanks to @simelis
- Migrated the library to use `Microsoft.Data.SqlClient` vs legacy `System.Data.SqlClient` which is no longer being updated with most improvements, especially performance and edge case bugs. From v1.1 onward we will only use `Microsoft.Data.SqlClient`.
- Added support to optimize Identity value updates with native performance (no reflection) by implementing ISqlBulkHelperIdentitySetter on the model classes.
- Fix to correctly support fully qualified table names with schema.
- Ensure BulkCopy also uses timeout parameter.
- Add Overloads for easier initialization of SqlMergeMatchQualifierExpression class.
- Breaking change; removed internal Default static references so that I can eliminate any dependency on Configuration framework for better support in .Net Core; New Caching helper and simple constructor with Sql Connection String replace this.
- Added support to specify SqlCommand Timeout Seconds when initializing the Sql Bulk Helper class, instead of relying on the connection wide setting from the Connection string.
- Added support for custom match qualifiers to be specified even if bulk inserting/updating data with Identity columns.  This addresses some edge use cases whereby data syncing may be taking place and Identities are used to differentiate data from multiple sources, but the actual merge matches needs to occur on unique fields of the source system.
- Simplified initialization and constructors to provide easier use -- especially if SqlConnection/SqlTransaction already exists and ConnectionString is not available.  It's still recommended to use ISqlBulkHelpersConnectionProvider however, this may not be congruent with existin code bases so now the use of existing Sql Connection & Transaction is encapsulated.
- Provided in-memory cache implementation to help manage caching of Schema DB Loaders for performance.
- Improved pattern for Schema DB Loader management and encourage use of new Caching class; previously its possible that this was being re-loaded multiple times unnecessarily due to relying on internal behavior instead of managing it as a static/singleton.
- Added more Integration Tests for Constructors and Connections, as well as the new DB Schema Loader caching implementation.
- Fixed bug in dynamic initialization of SqlBulkHelpersConnectionProvider and SqlBulkHelpersDBSchemaLoader when not using the Default instances that automtically load the connection string from the application configuration setting.
