Unable to write a value of type StrongGrid.Models.MailPersonalization => The IJsonTypeInfoResolver returned a JsonTypeInfo instance whose JsonSerializerOptions setting does not match the provided argument about stronggrid HOT 7 CLOSED

Thanks for reporting this and for the additional information. I'll look into it this weekend and report back what I find.

I still can't explain why this problem is occurring, but I can confirm that I am able to reproduce it when I create a new .net7 console app and reference the latest StrongGrid package from NuGet (which, by the way, targets .net5 and .net6). Is the problem related to some quirk when referencing a .net6 library from a .net7 project?

Maybe this is an argument in favor of expediting #463?

So far, I already faced (and fixed) one serialization problem caused by a change introduced in .net7 (explanation here, I fixed it here). This might be another similar situation.

I'm continuing my research...

I found the culprit and I know how to fix the issue, but I still can't explain why this problem occurs only when our library targets .net6 and it's used in a .net7 application.

An update should be available on NuGet tomorrow.

FWIW, this little bit in Program.cs reproduces the problem. It seems to be the MailPersonalization.CustomArguments that is the issue - comment that stuff out and it'll work without an error:

using StrongGrid;
using StrongGrid.Models;
using MailAddress = StrongGrid.Models.MailAddress;

const string sendGridKey = "your sendgrid key";

Console.WriteLine("Sending email...");

var client = new Client(sendGridKey);
var personalization = new MailPersonalization
{
    To = new[] { new MailAddress("[email protected]", "Ken Smith") },
    CustomArguments = new KeyValuePair<string, string>[]
    {
        new ("PolicyNumber", "some policy number"),
        new ("PolicyHolder", "some email address"),
    },
};

var contents = new List<MailContent>
{
    new("text/plain", "Hello plain world!"),
};

var result = await client.Mail.SendAsync(new List<MailPersonalization> { personalization },
    "Test Subject",
    contents,
    new MailAddress("[email protected]", "Ken Smith"),
    new List<MailAddress> { new("[email protected]", "Ken Smith") }
);

Console.WriteLine($"Sent email: {result}");
Console.ReadLine();
