-The body of an expression lambda can consist of a method call. However, when creating [expression trees](../../advanced-topics/expression-trees/index.md) evaluated by a query provider, limit method calls to those methods recognized by the query provider. Otherwise, the query provider can't replicate the method's function.
+The body of an expression lambda can consist of a method call. However, when creating [expression trees](../../advanced-topics/expression-trees/index.md) evaluated by a query provider, you should limit method calls to those methods that the query provider can handle. Different query providers have varying capabilities—for example, many SQL-based providers can translate methods like <xref:System.String.StartsWith%2A?displayProperty=nameWithType> into appropriate SQL expressions such as `LIKE`. If a query provider doesn't recognize a method call, it can't translate or execute the expression.
