I ended up fixing it this way:
protected void SetBuildTargets(Func<string[]> tasksAction)
{
foreach(var task in tasksAction())
BuildTasks.Add(task);
}
[Meta]
public static Expression tasks(params ReferenceExpression[] expressions)
{
var blockExpression = new BlockExpression();
var arrayExpression = new ArrayLiteralExpression();
for (var i = 0; i < expressions.Length; i++)
arrayExpression.Items.Add(new
StringLiteralExpression(expressions[i].Name));
blockExpression.Body.Add(new ReturnStatement(arrayExpression));
return new MethodInvocationExpression(
new ReferenceExpression("SetBuildTargets"),
blockExpression
);
}
