"ExecuteReader" error message or high CPU usage after the connection for database synchronization fails in Sync Framework 2.1. Consider the following scenario:You host your server synchronization logic in Microsoft .NET Framework 4.0-based Windows Communication Foundation (WCF) Services.You configure the PerSession member for the InstanceContextMode enumeration, and then you configure the Multiple member for the ConcurrencyMode enumeration.You enable batching for the sync provider of Sync Framework 2.1.You use Microsoft Sync Framework 2.1 to synchronize the database server with a client.An exception occurs while the change enumeration is still running.In this scenario, the synchronization may enter an infinite loop.
This results in either of the following behaviours:The CPU usage of the computer increases.You receive the following error message:ExecuteReader requires an open and available Connection. The connection's current state is open. This issue occurs because the database provider starts a second thread and uses a producer/consumer model to enumerate changes from the database server.

Changelog for 3.8.32. Base de données intégrée - Wikipedia, l'encyclopédie libre. An embedded database system is a database management system (DBMS) which is tightly integrated with an application software that requires access to stored data, such that the database system is "hidden" from the application’s end-user and requires little or no ongoing maintenance.
It is actually a broad technology category that includes database systems with differing application programming interfaces (SQL as well as proprietary, native APIs),database architectures (client-server and in-process),storage modes (on-disk, in-memory, and combined),database models (relational, object-oriented, entity–attribute–value model, network/CODASYL), andtarget markets. Conception d’applications du Windows Store – Centre de développement Windows. Extending "Windows 8" apps to the cloud with SkyDrive - Building Windows 8. Building on the recent post about signing in to Windows 8 with a Windows Live ID, we wanted to talk a bit about using SkyDrive from within new Windows 8 Metro style apps.
While apps get some amount of "automatic usage" of SkyDrive to roam settings, and the apps themselves roam, we know developers are anxious to make it easy for customers of their applications to have data they create roam easily across devices. SkyDrive is a great way to do this as every Windows Live ID has a free cloud-based drive. This post talks about how developers can build Metro style apps that use SkyDrive storage from within the apps.This is our first post with code--expect more of those! Mike Torres, the group program manager of the SkyDrive Devices and Roaming team, authored this post. --Steven Despite the trend towards multiple devices per person, many people still store all their important files on a single PC or storage device, and don’t have access to them from their other devices.

With the upcoming release of SQL Server 2012 comes a new variant of SQL Express called LocalDB, a feature that is least talked about compared to all the other new features in the SQL 2012 release.
I won’t go in deep detail to explain what LocalDB is, suffice to say, I like to think of it as something in between SQL Compact and SQL Express, a hybrid if you may, combining the ease-of-use of SQL Compact and the power of SQL Express. A SQL Express service that gets started and stopped as needed. To quote from the SQL Express Weblog: At a very high level, LocalDB has the following key properties:LocalDB uses the same sqlservr.exe as the regular SQL Express and other editions of SQL Server. The application is using the same client-side providers (ADO.NET, ODBC, PDO and others) to connect to it and operates on data using the same T-SQL language as provided by SQL Express.LocalDB is installed once on a machine (per major SQL Server version).
