public class RequiredIfAttribute : ValidationAttribute { private readonly string _condition; public RequiredIfAttribute(string condition) { _condition = condition; } protected override ValidationResult IsValid(object value, ValidationContext validationContext) { Delegate conditionFunction = CreateExpression( validationContext.ObjectType, _condition); bool conditionMet = (bool) conditionFunction.DynamicInvoke( validationContext.ObjectInstance); if (conditionMet) { if (value == null) { return new ValidationResult(FormatErrorMessage(null)); } } return null; } private Delegate CreateExpression(Type objectType, string expression) { // TODO - add caching LambdaExpression lambdaExpression = System.Linq.Dynamic.DynamicExpression.ParseLambda( objectType, typeof (bool), expression); Delegate func = lambdaExpression.Compile(); return func; } }these code we need "DynamicQuery" dll when we install core-shared libary we get the build errors in mobile projects

Does the Abp parameter validation component call the
IsValidmethod of theRequiredIfAttributeclass?Does
DynamicQueryhave no nuget packages? It is not recommended to use DLLs to manage project dependencies.
