CqlSharp 0.40.0

CqlSharp is a high performance, asynchronous Cassandra CQL binary protocol client implementing the ADO.NET data provider interfaces.

     It's main features are:
     * The API implements the ADO.NET interfaces. If you are familiar with SqlConnection, SqlCommand, and SqlReader, you should be able to use CqlSharp with no difficulty.
     * CqlSharp is an implementation of the (new) CQL Binary Protocol and therefore requires Cassandra 1.2 and up
     * CqlSharp supports all the binary protocol v2 features: batching, paging, bound query variables, result schema caching, check-and-set (CAS) statements, and sasl-authentication
     * Implements binary protocol v3: more queries per connection, timestamp property, UDT and Tuple types, larger collections
     * Supports fast mapping of objects to query parameters, or query results to objects. Mapping is tunable by decorating your classes via Table and Column attributes.
     * Query tracing, timeouts and cancellation is supported
     * The API is predominately [asynchronous](https://msdn.microsoft.com/en-us/library/vstudio/hh191443.aspx), heavily relying on the System.Threading.Tasks namespace. Synchronous alternatives are available for convenience.
     * Configuration is done through connection strings. The simultaneous use of multiple Cassandra clusters is supported.
     * Extensive logging, including support for custom logger implementations

Release Notes

## Version 0.40.0 - Cql Binary Protocol v3 and new type system
     * Implements binary protocol v3: more queries per connection, timestamp property, UDT and Tuple types, larger collections.
     * Rewrite of type system, CqlType is no longer an enum but a class with subclasses for every Cassandra type.
     * Previous CqlType enum is now called CqlTypeCode.
     * Primitive Cql types can be accessed through CqlType.* static properties. Others can be constructed from .NET class, type string, or TypeCode + parameter via the CqlType.CreateType overloads.
     * CqlParameter no longer accepts different CqlTypeCodes, but requires a single CqlType
     * Added high performance and extremely flexible type conversion that prevents boxing, and even converts collection types (e.g. hashset{int} to list{long})
     * Removed explicit references to collection key and value types. They are not used separate from the corresponding CqlTypes anymore
     * CqlDataReader.GetDataTypeName(int i) now returns full string representation of the Cassandra type (e.g. map{varchar, int=""})
     * CqlDataReader.GetFieldCqlType added that returns the CqlType used for the given field
     * Removed a lot of boxing/unboxing of primitive types during serialization/deserialization
     * Implemented DbDataReader.GetFieldValue{T}(int i)
     * Supports User Defined Types. Annotate your class with CqlUserType and CqlColumn to have it correctly mapped to a Cassandra User Defined Type
     * Guesses protocol version from release_version shortening connection setup times for older clusters
     ## Version 0.39.0 - Performance of sync operations
     * Many changes to have synchronous API really execute synchronously, it is no longer a sync-over-async wrapper
     * Improved exception generation in case of query cancellation or timeout
     * Logging cancelled queries
     * Fix: Adding LocalOne consistency level
