Getting “The connection does not support MultipleActiveResultSets” in a ForEach with async-await

Question

I have the following code using Dapper.SimpleCRUD :

var test = new FallEnvironmentalCondition[] {
    new FallEnvironmentalCondition {Id=40,FallId=3,Environm         


        

Answer 1

You need to add attribute MultipleActiveResultSets in connection string and set it to true to allow multiple active result sets.

 "Data Source=MSSQL1;" & _  
    "Initial Catalog=AdventureWorks;Integrated Security=SSPI;" & _  
    "MultipleActiveResultSets=True"
