MicroLite.Extensions.WebApi 6.6.0

The OData query parsing library which was spun out of the MicroLite WebApi extension has undergone quite a few changes and some of those have been incorporated into the MicroLite WebApi extension.

The main difference is that the OData query support has been split out into a separate library so if you want to use WebApi controllers but don’t use OData, you no longer have a dependency on the Net.Http.WebApi.OData library. Starting with version 6.6.0 of the MicroLite WebApi extension, there are now 2 packages available:

What do I need to do?

“I use the WebApi extension and want OData 4.0!”

  1. PM> Install-Package MicroLite.Extensions.WebApi.OData -Version 6.6.0

“I use the WebApi extension and don’t use OData query support”

  1. PM> Install-Package MicroLite.Extensions.WebApi -Version 6.6.0
  2. PM> Uninstall-Package Net.Http.WebApi.OData

Query Option Changes
$inlinecount=allpages has been replaced by $count=true.

The JSON response for paged results ($count=true) has changed as follows:

  1. data.__count is now data['@odata.count']
  2. data.results is now data.value

Function Changes
The substringof function has been replaced by contains in the $filter query option so substringof('Alfreds', CompanyName) would become contains(CompanyName, 'Alfreds')

Data Type Changes:
The DateTime type has been removed, there is a new Date type for dates only which is a literal and doesn’t need a type prefix or quotes $filter=DateOfBirth eq 1974-08-19. To specify date and time, use DateTimeOffset literal instead which also no longer requires a type prefix or quotes $filter=Created gt 2002-10-15T17:34:23Z don’t forget the timezone!.

The Guid type no longer requires a prefix or quotes TransactionId eq guid'0D01B09B-38CD-4C53-AA04-181371087A00' becomes TransactionId eq 0D01B09B-38CD-4C53-AA04-181371087A00

The library now requires the entity model to be defined, see the Wiki for further details.

MicroLite.Extensions.Mvc 6.3.0

MicroLite.Extensions.Mvc 6.3.0 has been released on NuGet.

The main changes in this release are:

  1. .NET 4.5 only build targeting ASP.NET MVC 5.2.3
  2. MicroLiteSessionAttribute has been removed, it is strongly recommended that you use an IOC container to manage dependencies.

This does mean that the release is not necessarily a “drop-in” update if you were previously using an older version of .NET or ASP.NET MVC.

To see the full set of changes, please refer to the Github release page

MicroLite.Extensions.WebApi 6.5.0

MicroLite.Extensions.WebApi 6.5.0 has been released on NuGet.

The main changes in this release are:

  1. .NET 4.5 only build targeting ASP.NET WebApi 5.2.3 and Net.Http.WebApi.OData 3.4.0
  2. MicroLiteSessionAttribute has been removed, it is strongly recommended that you use an IOC container to manage dependencies.

This does mean that the release is not necessarily a “drop-in” update if you were previously using an older version of .NET or ASP.NET WebApi.

Logging Extension Updates

The logging extensions for MicroLite have been updated as follows and are available on nuget.org.

log4net

The log4net extension has been updated to target log4net 2.0.5 or later and a .NET 4.6 compiled build has been added.

NLog

The NLog extension has been updated to target NLog 4.4.0 or later and a .NET 4.6 compiled build has been added.

Serilog

The Serilog extension has been updated to target Serilog 2.3.0 or later, a .NET 4.6 compiled build has been added and the .NET 4.0 build has been removed.

MicroLite 6.3.1

MicroLite 6.3.1 has been released and it is strongly recommended that anyone using 6.3.0 upgrades immediately.

A defect has been identified in 6.3.0 whereby the Identifier value of a newly inserted record isn’t set on the object. This was inadvertently introduced when the Listener code was refactored in 6.3.0 so it only affects that version which has now been hidden on nuget.org.

Upgrading to MicroLite 6.3

MicroLite 6.3.0 has been released on NuGet, the main changes in this release are detailed below.

New Convention Mappings

There are now 2 new helper convention mappings:

  1. ConventionMappingSettings.LowercaseWithUnderscores – Maps a Pascal Cased property name to an underscore separated lower cased column e.g. a property called ‘CreditCard’ would map to a column called ‘credit_card’
  2. ConventionMappingSettings.UppercaseWithUnderscores – Maps a Pascal Cased property name to an underscore separated upper cased column e.g. a property called ‘CreditCard’ would map to a column called ‘CREDIT_CARD’

DateTime mapping

The default mapping for System.DateTime is now System.Data.DbType.DateTime2. If you need to change it back to System.Data.DbType.DateTime do the following:

// In startup code (before calling Configure.Fluently()...):

// Reset the DbType mapping for DateTime:
TypeConverter.RegisterTypeMapping(typeof(DateTime), DbType.DateTime);
TypeConverter.RegisterTypeMapping(typeof(DateTime?), DbType.DateTime);

XDocument mapping

The default mapping for System.Xml.Linq.XDocument is now System.Data.DbType.Xml. If you need to change it back to System.Data.DbType.String do the following:

// In startup code (before calling Configure.Fluently()...):

// Reset the DbType mapping for XDocument:
TypeConverter.RegisterTypeMapping(typeof(XDocument), DbType.String);

Upgrading to MicroLite 6.2

MicroLite 6.2.0 has been released on NuGet.

The 2 main changes in this release are:

  • The session re-uses the same command during its lifecycle so multiple operations via a session are more efficient – especially multiple operations of the same type (e.g. multiple inserts).
  • Improved the handling of TimeSpan – beware that this is a breaking change (see below)

Prior to MicroLite 6.2, MicroLite was able to map a TimeSpan to a MS SQL Time column – however it turns out there are a number of problems with the Time type:

  1. It has a maximum value of 24:00:00 since it is actually designed to represent the time of day
  2. It cannot be used in some aggregate functions such as SUM and AVERAGE which makes summarising data diffucult

In order to mitigate these issues, MicroLite 6.2 now maps TimeSpan to a BIGINT by persisting the tick count of the TimeSpan – this has the added benefit of also enabling TimeSpan to be used by any database supported by MicroLite.

If you are updating to MicroLite 6.2 and you are currently using TimeSpan -> TIME you have 2 options:

1) – Update your database schema to use a BIGINT (add a new column, populate it by casting the time as the tick count, remove the old column).

2) – Configure MicroLite 6.2 to behave like MicroLite 6.1:

// In startup code (before calling Configure.Fluently()...):

// 1. Remove the new TimeSpanTypeConverter:
var timeSpanTypeConverter = TypeConverter.Converters.OfType<TimeSpanTypeConverter>().Single();
TypeConverter.Converters.Remove(timeSpanTypeConverter);

// 2. Reset the DbType mapping for TimeSpan:
TypeConverter.RegisterTypeMapping(typeof(TimeSpan), System.Data.DbType.Time);
TypeConverter.RegisterTypeMapping(typeof(TimeSpan?), System.Data.DbType.Time);
