## Remarks
<xref:System.Activities.Expressions.LambdaReference%601> is used for lambda expressions specified in code and cannot be serialized to XAML. If an attempt to serialize a workflow that contains a <xref:System.Activities.Expressions.LambdaReference%601> is made, a <xref:System.Activities.Expressions.LambdaSerializationException> is thrown. If the containing workflow requires XAML serialization, use <xref:Microsoft.VisualBasic.Activities.VisualBasicReference%601> or use <xref:System.Activities.Expressions.ExpressionServices> to convert the <xref:System.Activities.Expressions.LambdaReference%601> to a format that can be serialized.
This activity uses the LINQ to Entity provider to evaluate LINQ expressions. Any LINQ expressions used with this activity must be evaluatable by the ADO.Net Entity Data Model. For example, LINQ expressions cannot be used to reference activities, variables, or arguments of the workflow itself.
