Minimal Actions - array support in method signatures from querystring binding #32516
Description
Describe the bug
When using the ASPP.NET 6 minimal hosting, querystring binding does not work with arrays/lists
To Reproduce
app.MapGet("/qs/{id:int}", HttpHandlers.GetByQueryString);
public static string GetByQueryString(int id, string name, int[] values)
{
return id + " " + name + string.Join(",", values);
}Adding [FromQuery(Name = "values")] to the method signature does not help either.
Exceptions (if any)
An exception is thrown when sending in a request:
curl http://localhost:5000/qs/123\?name\=dave\&values\=1\&values\=2
Unhandled exception. System.InvalidOperationException: No public static bool Int32[].TryParse(string, out Int32[]) method found for values.
