The following array collection expression with spread operator fails on .Net SDK version 8.0.204 but works on SDK version 8.0.104.

VsCode Version: 1.89.0

OS: Windows 10

Dotnet version: .Net 8

C# Language Version: 12

Code that raises the exception

Type[] types = [
        .. Assembly.GetAssembly(typeof(Application.DependencyInjection))!
                   .GetTypes(),
        .. Assembly.GetAssembly(typeof(Infrastructure.DependencyInjection))!
                   .GetTypes()
    ];

Full Exception

Exception has occurred: CLR/System.ArrayTypeMismatchException
Exception thrown: 'System.ArrayTypeMismatchException' in System.Private.CoreLib.dll: 'Attempted to access an element as a type incompatible with the array.'
   at System.ThrowHelper.ThrowArrayTypeMismatchException()
   at System.Span`1..ctor(T[] array)
   at Webmonitor.Infrastructure.Data.Dapper.DapperMappingRegistration.RegisterDapperMappers() in C:MahbuburProjectsWM 4NextGenAPIWebmonitor.InfrastructureDataDapperDapperMappingRegistration.cs:line 21

Full code

public static void RegisterDapperMappers()
{
    Type[] types = [
        .. Assembly.GetAssembly(typeof(Application.DependencyInjection))!
                   .GetTypes(),
        .. Assembly.GetAssembly(typeof(Infrastructure.DependencyInjection))!
                   .GetTypes()
    ];

    var typesWithColumnAttributes = types
        .Where(t => t.GetProperties().Any(p => p.GetCustomAttribute<ColumnAttribute>() is not null))
        .Where(t => !t.IsInterface && !t.IsAbstract);

    foreach (var type in typesWithColumnAttributes)
    {
        SqlMapper.SetTypeMap(type, new DapperCustomAtrributeMapper(type));
    }
}

Removing the collection expression works.

Type[] types = Assembly
            .GetAssembly(typeof(Webmonitor.Application.DependencyInjection))!
            .GetTypes()
            .Concat(Assembly.GetAssembly(typeof(Webmonitor.Infrastructure.DependencyInjection))!.GetTypes())
            .ToArray();

Going back to older .net sdk version 8.104 works too.
