Hello,

I am running this bit of code from an MVC controller. The method has the UnitOfWork attribute and is virtual,

This is the bit of code where the exception is thrown

var roles = await _roleManager.Roles.Where(r => r.IsDefault).ToListAsync();

This is the exception that is being thrown

System.Reflection.AmbiguousMatchException occurred HResult=-2147475171 Message=Ambiguous match found.

    Hi,

    You might have two Id fields in one of your entities.

    If it is not the case, can you share a bit more part of your controller code. And which versions of ABP do you use ?

    @ismcagdas What would define an Id field? If it is just a field named "Id" then i can't think of any that would have duplicates.

    Here is a bit of the controller code

    [HttpPost]
        [UnitOfWork]
        public virtual async Task<ActionResult> CreateUser(CreateUserViewModel model)
        {
            try
            {
                CheckModelState();

                // Validation code removed 

                // Switch to the tenant
                if (tenant != null)
                {
                    _unitOfWorkManager.Current.EnableFilter(AbpDataFilters.MayHaveTenant);
                    _unitOfWorkManager.Current.SetTenantId(tenant.Id);
                }

                // Add default roles
                user.Roles = new List<UserRole>();
                var roles = await _roleManager.Roles.Where(r => r.IsDefault).ToListAsync();

                if (roles.Any())
                {
                    foreach (var defaultRole in roles)
                    {
                        user.Roles.Add(new UserRole { RoleId = defaultRole.Id });
                    }
                }                

                // Save User
                CheckErrors(await _userManager.CreateAsync(user));
                await _unitOfWorkManager.Current.SaveChangesAsync();


            }
            catch (UserFriendlyException ex)
            {
                ViewBag.ErrorMessage = ex.Message;

                return View("CreateUser", model);
            }
        }

    I've removed some validation code at the top as this works. Just on another note as well, if i comment out the code that throws the exception, then another slice of code also throws the same exception

    CheckErrors(await _userManager.CreateAsync(user));

    Thanks
