FromQuery Error: InvalidOperationException: No public static bool GenericFilter.TryParse(string, out GenericFilter) method found for filter.

I'm Currently trying out AutoFilterer and it works well with using FromBody but not with FromQuery

Below are the full error message generated, i'm sticking to using FromBody for not just wanted to report the issue.

It seems it's an AspNetCore binding error. Your value might have some special characters or something that can break the binding

I thought so initially, below is the sample filter used.

// Sample filter
public class GenericFilter : PaginationFilterBase{ }

// Sample DTO
public class SampleDto : FilterBase {
public Guid Id { get; set; }
public string Name { get; set; }
}

I understand the problem but nothing to do in autofilterer library. Autofilterer generates only LINQ expressions and it doesn't know about your aspnetcore application or how to bind object properties.

There is no aspnetcore dependency of autofilterer. https://github.com/enisn/AutoFilterer/blob/5e55bbf819bc1640ba2286d8fc7c8fc10a8dfdf1/src/AutoFilterer/AutoFilterer.csproj#L5-L22

You may ask your question at dotnet/aspnetcore repositroy

I was able to use fine on dotnet 7 with the new AsParameters which is better for minimal API

Here

group.MapGet("/", async ([FromServices] CategoryService sv, [AsParameters] CategoryFilter filter) => await sv.GetAllAsync(filter))
            .WithName($"GetAll{name}")
            .WithOpenApi();

Might be similar with https://github.com/dotnet/aspnetcore/issues/40752
