Wait for form task error

Hi,
When i used wait for form activity it is showing error System.Exception: Type ‘System.Text.ASCIIEncoding+ASCIIEncodingSealed’ cannot be serialized. Consider marking it with the DataContractAttribute attribute, and marking all of its members you want serialized with the DataMemberAttribute attribute. Alternatively, you can ensure that the type is public and has a parameterless constructor - all public members of the type will then be serialized, and no attributes will be required.Whats the exact problem for i have 3-4 files need to be validated so i used wait for form activity after the for loop but it is throwing error please help me to resolve this problem
Regards,
Sainath

Hello @SainathReddy

  1. Avoid using the problematic type if possible.
  2. If using custom code, mark the type with DataContractAttribute and members with DataMemberAttribute.
  3. Check your custom code or activities for any references to the mentioned type.

Thanks & Cheers!!!
