Flu.net

A tool that helps you creating your own fluent syntax for .NET Framework applications in a declarative fashion.

It is aimed for infrastructures and other open-source projects use.

Example

To create a simple fluent syntax for DataTables, all we need to do is declare the following interfaces:

[Inherited]
[Scope("DataTable")]
public interface IDataTableSyntax
{
    [UniqueInScope("DataTable")]
    [Alias("PrimaryKey")]
    IDataColumnSyntax<T> WithPrimaryKey<T>(string name);

    IDataColumnSyntax<T> WithColumn<T>(string name);
}

[Scope("DataColumn")]
public interface IDataColumnSyntax<T>
{
    [UniqueInScope("DataColumn")]
    IDataColumnSyntax<T> MakeNullable();

    [UniqueInScope("DataColumn")]
    IDataColumnSyntax<T> WithDefaultValue(T value);

    [UniqueInScope("DataTable")]
    [Alias("PrimaryKey")]
    IDataColumnSyntax<T> MakePrimaryKey();
}

We generate a fluent syntax using Flu.net. The generated fluent syntax ensures we can't call WithPrimaryKey/MakePrimaryKey more than once, and that we that we can't call MakeNullable/WithDefaultValue more than once per a declared DataColumn.
