    copied!<p>You could supply the connection string as a constructor argument when binding the <code>SqlProductRepository</code> to the <code>IProductRepository</code> interface.</p> <pre><code>public class LinqToSqlModule : NinjectModule { public override void Load() { Bind&lt;IProductRepository&gt;().To&lt;SqlProductRepository&gt;() .WithConstructorArgument(connectionString, "connectionstring"); } } </code></pre> <p>I would suggest a slightly different approach. First of all, you might want to create a binding for the <code>DataContext</code> class in the kernel. You could do so by using a provider class to create your <code>DataContext</code> passing the connection string as an argument to its constructor. Then you bind the <code>DataContext</code> to the <code>DataContextProvider</code>.</p> <pre><code>public class DataContextProvider : Provider&lt;DataContext&gt; { protected override DataContext CreateInstance(IContext context) { string connectionString = "connectionstring"; return new DataContext(connectionString); } } public class LinqToSqlModule : NinjectModule { public override void Load() { Bind&lt;DataContext&gt;().ToProvider&lt;DataContextProvider&gt;(); Bind&lt;IProductRepository&gt;().To&lt;SqlProductRepository&gt;(); } } </code></pre> <p>Next modify the constructor of <code>SqlProductRepository</code> class to accept a <code>DataContext</code> object instead.</p> <pre><code>public class SqlProductRepository : IProductRepository { private readonly DataContext context; public ProductRepository(DataContext context) { this.context = context; } public IQueryable&lt;Product&gt; Products { get { return context.GetTable&lt;Product&gt;(); } } } </code></pre> <p>By the way you don't have to decorate your constructor with the <code>Inject</code> attribute. Ninject will select the constructor with the most parameters by default.</p>
