when this type is registered as an EF provider either using an entry in the application's config file
or through code-based registration in .
The services resolved are:
Requests for are resolved to a Singleton instance of
to create connections to SQL Express by default.
Requests for for the invariant name "System.Data.SqlClient"
for any server name are resolved to a delegate that returns a

parameter and targeted for the version of the database corresponding to the provider manifest token.

A DDL script that creates schema objects based on the contents of the StoreItemCollection parameter
and targeted for the version of the database corresponding to the provider manifest token.
Create the database and the database objects.
If initial catalog is not specified, but AttachDBFilename is specified, we generate a random database name based on the AttachDBFilename.
Note: this causes pollution of the db, as when the connection string is later used, the mdf will get attached under a different name.
However if we try to replicate the name under which it would be attached, the following scenario would fail:
The file does not exist, but registered with database.
The user calls: If (DatabaseExists) DeleteDatabase
CreateDatabase
For further details on the behavior when AttachDBFilename is specified see Dev10# 188936
Connection to a non-existent database that needs to be created and populated with the store objects indicated with the storeItemCollection parameter.
Execution timeout for any commands needed to create the database.
The collection of all store items based on which the script should be created.
Determines whether the database for the given connection exists.
There are three cases:
1. Initial Catalog = X, AttachDBFilename = null: (SELECT Count(*) FROM sys.databases WHERE [name]= X) > 0
2. Initial Catalog = X, AttachDBFilename = F: if (SELECT Count(*) FROM sys.databases WHERE [name]= X) > 0 then true,
if not, try to open the connection and then return (SELECT Count(*) FROM sys.databases WHERE [name]= X) > 0
3. Initial Catalog = null, AttachDBFilename = F: Try to open the connection. If that succeeds the result is true, otherwise
if the there are no databases corresponding to the given file return false, otherwise throw.
Note: We open the connection to cover the scenario when the mdf exists, but is not attached.
Given that opening the connection would auto-attach it, it would not be appropriate to return false in this case.
Also note that checking for the existence of the file does not work for a remote server. (Dev11 #290487)
For further details on the behavior when AttachDBFilename is specified see Dev10# 188936
Connection to a database whose existence is checked by this method.
Execution timeout for any commands needed to determine the existence of the database.
The collection of all store items from the model. This parameter is no longer used for determining database existence.

Determines whether the database for the given connection exists.

2. Initial Catalog = X, AttachDBFilename = F: if (SELECT Count(*) FROM sys.databases WHERE [name]= X) > 0 then true,
if not, try to open the connection and then return (SELECT Count(*) FROM sys.databases WHERE [name]= X) > 0
3. Initial Catalog = null, AttachDBFilename = F: Try to open the connection. If that succeeds the result is true, otherwise
if the there are no databases corresponding to the given file return false, otherwise throw.

Execution timeout for any commands needed to determine the existence of the database.
The collection of all store items from the model. This parameter is no longer used for determining database existence.
True if the provider can deduce the database only based on the connection.
Delete the database for the given connection.
There are three cases:
1. If Initial Catalog is specified (X) drop database X
2. Else if AttachDBFilename is specified (F) drop all the databases corresponding to F
if none throw
3. If niether the catalog not the file name is specified - throw
Note that directly deleting the files does not work for a remote server. However, even for not attached
databases the current logic would work assuming the user does: if (DatabaseExists) DeleteDatabase

The Singleton instance of the SqlProviderServices type.
Set to the full name of the Microsoft.SqlServer.Types assembly to override the default selection
Get or sets a value indicating whether parameter values are truncated to
the scale (number of decimal places) defined for their corresponding columns when they are sent
to the database. A value of true indicates that objects
created for columns will have their
properties set, which will cause the parameter values to be truncated. If set to false
then the properties will not be set, avoiding the truncation
behavior of and allowing SQL Server to round values if necessary.
The default value is true to prevent breaking existing applications that depend on this
behavior.
Gets or sets a value indicating whether to use the SCOPE_IDENTITY() function to retrieve values
generated by the database for numeric columns during an INSERT operation. The default value of
true is recommended and can provide better performance if all numeric values are generated
using IDENTITY columns. If set to false, an OUTPUT clause will be used instead. An OUTPUT
clause makes it possible to retrieve values generated by sequences or other means.
Gets or sets a value indicating whether the ROW_NUMBER() function is used in sort expression
passed to the ORDER BY clause when OFFSET is present in query. The default value of true
is recommended to obtain query results that are stable for paging operations. The value of
false can be used for compatibility with previous versions of EF and will cause the sort
expression to be passed unmodified to the ORDER BY clause, which can lead to unstable results
if the ordering is ambiguous.
This flag only applies to SQL Server 2012 or later. This flag does not affect queries that have
already been translated to SQL and cached, therefore applications that need to set the value to
false for compatibility should do so before executing any queries.
An implementation of to provide support for geospatial types when using
Entity Framework with Microsoft SQL Server.
