问题 I am using Entity Framework 4 in a desktop application with SQL Compact. I want to use a private installation of SQL Compact with my application, so that my installer can install SQL Compact without giving the user a second installation to do.

This is really just me shooting the breeze and trying to figure this out. I don\'t plan to

问题 when I tried to create a new SQL Server Compact file from Visual Studio -> Add New Item, I don\'t see the \'Local Database\' option any more which was actually the way to add SQL Server Compact Database. Now, if it is really discontinued from Microsoft, then, what is the recommended Embedded Database technology from Microsoft for Desktop Applications ? I tried SQLite but deployment is headache for SQLite because, the user may not have correct version of Visual C++ distributable installed in

问题 I have following C# code in a console application. Whenever I debug the application and run the query1 (which inserts a new value into the database) and then run query2 (which displays all the entries in the database), I can see the new entry I inserted clearly. However, when I close the application and check the table in the database (in Visual Studio), it is gone.
