Version History

1.0.77.0 - November XX, 2011

Updated to SQLite 3.7.9 [c7c6050ef0].
More enhancements to the build and test automation.
Support building the core System.Data.SQLite assemblies using the .NET Framework 4.0 Client Profile. Fix for [566f1ad1e4].
When returning schema information that may be used by the .NET Framework to construct dynamic SQL, use a fake schema name (instead of null) so that the table names will be properly qualified with the catalog name (i.e. the attached database name). Partial fix for [343d392b51].
Add DateTimeKind connection string property to control the DateTimeKind of parsed DateTime values. Partial fix for [343d392b51].
Improve the robustness of the SQLiteLog class when it will be initialized and unloaded multiple times.
Fix the name of the interop assembly for Windows CE. Add unit tests to prevent this type of issue from happening again. Fix for [737ca4ff74].
Formally support the SQL type name BOOLEAN in addition to BOOL. Fix for [544dba0a2f].
Make sure the SQLiteConvert.TypeNameToDbType method is thread-safe. Fix for [84718e79fa].

1.0.76.0 - October 4, 2011

Prevent the domain unload event handler in SQLiteLog from being registered multiple times. Fix for [0d5b1ef362].
Stop allowing non-default application domains to initialize the SQLiteLog class. Fix for [ac47dd230a].

Version History

+ 1.0.77.0 - November XX, 2011 +

Updated to SQLite 3.7.9 [c7c6050ef0].
More enhancements to the build and test automation.
Support building the core System.Data.SQLite assemblies using the .NET Framework 4.0 Client Profile. Fix for [566f1ad1e4].
When returning schema information that may be used by the .NET Framework to construct dynamic SQL, use a fake schema name (instead of null) so that the table names will be properly qualified with the catalog name (i.e. the attached database name). Partial fix for [343d392b51].
Add DateTimeKind connection string property to control the DateTimeKind of parsed DateTime values. Partial fix for [343d392b51].
Improve the robustness of the SQLiteLog class when it will be initialized and unloaded multiple times.
Fix the name of the interop assembly for Windows CE. Add unit tests to prevent this type of issue from happening again. Fix for [737ca4ff74].
Formally support the SQL type name BOOLEAN in addition to BOOL. Fix for [544dba0a2f].
Make sure the SQLiteConvert.TypeNameToDbType method is thread-safe. Fix for [84718e79fa].

1.0.76.0 - October 4, 2011
