Log file name created by the ObjectContext.CreateDatabase method has changed to match SQL Server specifications

Change Description

When the xref:System.Data.Objects.ObjectContext.CreateDatabase?displayProperty=name method is called either directly or by using Code First with the SqlClient provider and an AttachDBFilename value in the connection string, it creates a log file named filename_log.ldf instead of filename.ldf (where filename is the name of the file specified by the AttachDBFilename value). This change improves debugging by providing a log file named according to SQL Server specifications.

• Quirked
• Build-time break

Recommended Action

If the log file name is important for an app, the app should be updated to expect the standard _log.ldf file name format.

Affected APIs

• M:System.Data.Objects.ObjectContext.CreateDatabase
