Different exception handling for ObjectContext.CreateDatabase and DbProviderServices.CreateDatabase methods

Scope

Minor

Version Introduced

4.5

Source Analyzer Status

Available

Change Description

Beginning in .NET 4.5, if database creation fails, CreateDatabase methods will attempt to drop the empty database. If that operation succeeds, the original xref:System.Data.SqlClient.SqlException?displayProperty=name will be propagated (instead of the xref:System.InvalidOperationException?displayProperty=name that was always thrown in .NET 4.0)

• Quirked
• Build-time break

Recommended Action

When catching an xref:System.InvalidOperationException?displayProperty=name while executing xref:System.Data.Objects.ObjectContext.CreateDatabase or xref:System.Data.Common.DbProviderServices.CreateDatabase(System.Data.Common.DbConnection,System.Nullable{System.Int32},System.Data.Metadata.Edm.StoreItemCollection), SQLExceptions should now also be caught.

Affected APIs

• M:System.Data.Objects.ObjectContext.CreateDatabase
• M:System.Data.Common.DbProviderServices.CreateDatabase(System.Data.Common.DbConnection,System.Nullable{System.Int32},System.Data.Metadata.Edm.StoreItemCollection)
