Quick Interview Answer

Query syntax is the SQL-like C# syntax that uses keywords such as from, where, orderby, select, group, and join. The compiler translates supported query expressions into calls to standard LINQ methods.

Detailed Explanation

Query syntax can be especially readable for complex joins or grouping, but it does not provide a fundamentally different execution engine from the equivalent method syntax.

Code Example

var result =
    from product in products
    where product.Price > 100
    orderby product.Name
    select product;
