Getting this exception "The type initializer for 'Npgsql.PoolManager' threw an exception." only on window 7.



public string ValidateDefaultInstancePostgreSqlServer()
{
string found = "0";

try

using (NpgsqlConnection postGresConnection = new NpgsqlConnection())

postGresConnection.ConnectionString = "Server=localhost;Port=5432;Database=postgres;User Id=postgres;Password=postgre123;Pooling=true;MinPoolSize=1;MaxPoolSize=100;Command Timeout=600;Timeout=600;";
using (NpgsqlCommand checkDBCommand = postGresConnection.CreateCommand())

postGresConnection.Open();

          I resolved my issue by updating System.ValueTuple.dll with the latest version. The issue came out to be the incompatibility between the Npgsql.dll and System.ValueTuple.dll.



          I think, if we have added references from nuget, the issue would not have came in first place.
          but strange it came only on window 7 or 32 bit machine.
