Install

You can install LinqSharp through NuGet：

Package Manager

Install-Package LinqSharp
Install-Package LinqSharp.EFCore

.NET CLI

dotnet add package LinqSharp
dotnet add package LinqSharp.EFCore

Try using the sample database

Northwnd, an early sample database shipped with SQL Server, describes a simple "enterprise sales network" scenario.

The database includes a network of employees, orders, and suppliers.

The NuGet version of Northwnd is a SQLite database (Code First).

Repository：https://github.com/zmjack/Northwnd

You can install Northwnd through NuGet：

Install-Package Northwnd

dotnet add package Northwnd

Then, you can try LinqSharp:

using (var context = NorthwndContext.UseSqliteResource())
{
    ...
}

For example:

using (var sqlite = NorthwndContext.UseSqliteResource())
{
    var query = sqlite.Shippers.Where(x => x.CompanyName == "Speedy Express");
    var sql = query.ToSql();
}

The variable sql is:

SELECT "x"."ShipperID", "x"."CompanyName", "x"."Phone"
FROM "Shippers" AS "x"
WHERE "x"."CompanyName" = 'Speedy Express';
