2.0.4

Primary changes:

• remove the System.Data.SqlClient dependency, allowing consumers to use System.Data.SqlClient or Microsoft.Data.SqlClient (or neither, or both) as they choose
• this means that some users may need to re-add one of the above as a <PackageReference> for their project to build, if they were previously relying on Dapper to provide System.Data.SqlClient
• the AsTableValuedParameter(this IEnumerable<SqlDataRecord>) extension method is now AsTableValuedParameter<T>(this IEnumerable<T>) where T : IDataRecord; this is a breaking change but should be code-compatible and just requires a rebuild
• unify the target platform at NetStandard2.0 (and .NET Framework 4.6.2 for the EF DB geometry/geography types)
• fix bug with Identity not enforcing type identity of multi-mapped types

Other changes merged:

• fix #1242, #1280, #1282 - fix value-tuple mapping
• fix #1295 - add ExecuteReaderAsync overload to expose DbDataReader
• fix #569 - handing of IN and similar clauses in some scenarios
• fix #1256 - make Dispose() polymorphic in "rainbow"
• fix #1257 - make the .Connection available in "rainbow"

• improve performance of descriptor API

1.60.5

1.60.1

• Fix #1196 - versioning fix only (#1198) - assembly version is now locked at 1.60.0 to resolve some mismatch issues with .NET Core assembly loading/binding.

1.50.7

• Fix #1190 - incorrect unmanaged pointer when processing parameters that are a boxed struct (rare error relating to GC)
• Fix #1111 - make SqlMapper.Parse consistent with QueryImpl
• Fix #111- - improve error message for invalid literal types
• Fix #1149 - improve error messages in "contrib"
• Improved detection of empty table-valued-parameters

1.50.5

• Fixes empty result set hanging with QueryAsync
• DapperRow now implements IReadOnlyDictionary<string, object>
• Improved error messages for Async when the provided IDbConnection is not a DbConnection
• Contrib: GetAll now handles nullable types

1.50.4

1.50.2

• Fix issue #569 (in expansions using ODBC pseudo-positional arguments)

1.50.1

• Change to how string_split is used for InListStringSplitCount

1.50.0

• No changes; stable release

1.50.0-rc3

• Updated for .Net Core RTM package dependencies

1.50.0-rc2b

• New InListStringSplitCount global setting; if set (non-negative), in @foo expansions (of at least the specified size) of primitive types (int, tinyint, smallint, bigint) are implemented via the SQL Server 2016 (compat level 130) STRING_SPLIT function
• Fix for incorrect conversions in GridReader (#254)

1.50.0-rc2 / 1.50.0-rc2a

• Packaging for .NET Core rc2

1.50-beta9

• Fix for PadListExpansions to work correctly with not in scenarios; now uses last non-null value instead of null; if none available, don't pad
• Fix problems with single-result/single-row not being supported by all providers (basically: sqlite, #466)

• Add support for C# 6 get-only properties (#473)
• Add support for various xml types (#427)

1.50-beta8

• Addition of GetRowParser<T> extension method on IDataReader API - allows manual construction of discriminated unions, etc
• Addition of Settings.PadListExpansions - reduces query-plan saturation by padding list expansions with null values (opt-in, because on some DB configurations this could change the meaning) (note: bad choice of null revised in 1.50-beta9)
• Addition of Settings.ApplyNullValues - assigns (rather than ignores) null values when possible
• Fix for #461 - ensure type-handlers work for constructor-based initialization
• Fix for #455 - make the LookupDbType method available again

1.50-beta7

• Addition of GetRowParser(Type) (and refactor the backing store for readers to suit)
• Column hash should consider type, not just name

• Fix for proxy-generator (issue #361)

1.50-beta4

• Add QueryFirstOrDefault / ReadFirstOrDefault methods that optimize the single-row scenario

• Core CLR now targets rc1 / 23516
• Various Core CLR fixes
• Code cleanup and C# 6 usage (assorted)

1.37

• Reuse StringBuilder instances when possible (list parameters in particular)

1.36

• Fix Issue #192 (expanded parameter naming glitch) and Issue #178 (execute reader now wraps the command/reader pair, to extend the command lifetime; note that the underlying command/reader are available by casting to IWrappedDataReader)

1.35

• Fix Issue #151 (Execute should work with ExpandoObject etc); Fix Issue #182 (better support for db-type when using object values);
• Output expressions / callbacks in dynamic args (via Derek); arbitrary number of types in multi-mapping (via James Holwell);
