I have got to say that you guys are the most responsive group when it comes to fixing bugs. Many of the problems I have posted about have specifically been addressed in a subsequent release of your dotConnect for SQLite or Entity Developer products. This one wasn't even a complaint and you fixed it anyway. Thank you! Please keep up the great customer service, you guys are awesome!

...Really like your product, by the way. I had previously used the EFSQLiteProvider example provided by MS, and actually got that working in our system, but was it ever slow!! Installing dotConnect for SQLite was easy, and the speed improvement was obvious.

Frequently Asked Questions

What is dotConnect for SQLite used for?

dotConnect for SQLite is an enhanced data provider for SQLite that builds on ADO.NET technology to present a complete solution for developing SQLite-based database applications. As part of the Devart database application development framework, dotConnect for SQLite offers both high performance native connectivity to the SQLite database and a number of innovative development tools and technologies. It also introduces new approaches for designing application architecture, boosts productivity, and leverages database application implementation.

How to deploy an app written with dotConnect for SQLite?

To deploy applications written with dotConnect for SQLite you should register run-time assemblies Devart.Data.SQLite.dll and Devart.Data.dll at Global Assembly Cache (GAC) for appropriate framework or place them in the folder of your application (Bin folder for web projects). These two assemblies should be available in all applications written with dotConnect for SQLite. Make sure that your project contains the license resource as it is described in Licensing.

Your application should also have access to the sqlite3.dll library. This library can be located either in the application folder or in a system-wide accessible folder. The bitness (32-bit or 64-bit) of the library must correspond to the bitness of your application.

How to install and configure dotConnect for SQLite?

dotConnect for SQLite is provided as a single setup package and contains all required files for Full .NET Framework and documentation. You can easily download it from the Devart website.

To connect to SQLite database in design-time, follow the steps below:

Run an IDE.
Open Toolbox and find SQLiteConnection component in dotConnect for SQLite Data tab.
Double-click the component. Note that new object appears on the designer underneath the form. If this is first time you create SQLiteConnection in this application, it is named sqLiteConnection1.
Click on the sqLiteConnection1 object and press F4 to focus on object's properties.
Set the ConnectionString property to "FailIfMissing=False;". This will allow dotConnect for SQLite to create the needed file. If you already have the database file, you may skip this step.
Specify the path to your database file in the DataSource property. E.g.: D:\TestApplication\database.db.
Note that as you assign values to these properties the ConnectionString property is automatically updated to reflect your settings. Now it contains something like Data Source=D:\TestApplication\database.db;FailIfMissing=False.
