Started a new Blazor WebAssembly project (Windows 10, Visual Studio 2019), trying to get a simple list via HttpClient from the server side.

Error:

Server side (this returns properly):
    [HttpGet]

        var users = await UserService.GetUsers();
        return users;
client side: doesn't render anything despite getting results back.

Would appreciate any help. Thanks.
Edit: Models:
public class UserDetailsRM :  IIntEntity
    public int Id { get; set; }
    public int UserDetailsId { get; set; }
    public string UserId { get; set; }
    public string FirstName { get; set; }
    public string LastName { get; set; }
    public DateTime Birthdate { get; set; }
    public int UserGenderOptionId { get; set; }
    private string gender;
    public string Gender
        get { return gender; }
            if (value == "1")
                gender = "Male";
            else if (value == "2")
                gender = "Female";
                gender = "Other";
    public string FullName
            return $"{FirstName} {LastName}";
            FullName = value;
    public int Age
            var today = DateTime.Today;
            var age = today.Year - Birthdate.Year;
            if (Birthdate.Date > today.AddYears(-age)) age--;
            return age;
    public string ProfileImageUrl { get; set; }
                Can you post the code of the relevant model(s) and  UserService.GetUsers. You may have  a circular reference issue...

                This model worked on a Blazor Server app as it is, but not on WASM. This indeed was the problem. Thanks!

                In my case, I was assigned the value to a different variable in the set method and encountered such an error, removing the set method worked. But, why this happens? what if we need such get set methods?

                I think the issue here is that the set accessor is trying to assign the value to the property name instead of a backing field. I guess there won't be any issue with this( need verification), but the source of the get accessor won't be the backing field. Again, I'm only guessing. I might be wrong...perhaps the framework won't accept that...

                The issue there is its setting FullName to itself which sets it to self ad infinitium - so basically its an infinite recursion and it runs out of memory. Quite ironically this is what causes stack overflow errors :) but thanks for this question as it shows me i have must have done the same somewhere in my code with a recent change as I am also getting this error and yes it would have happened anywhere the code is run - even on blazor server

5.0.0-rc.2.20475.17

For 3.2.1

<PackageReference Include="Newtonsoft.Json" Version="12.0.3" />
<PackageReference Include="System.Net.Http.Json" Version="3.2.0" />
For 5.0 rc2
<PackageReference Include="Microsoft.AspNetCore.Components.WebAssembly" Version="5.0.0-rc.2.20475.17" />
<PackageReference Include="Microsoft.AspNetCore.Components.WebAssembly.DevServer" Version="5.0.0-rc.2.20475.17" PrivateAssets="all" />
<PackageReference Include="Newtonsoft.Json" Version="12.0.3" />
<PackageReference Include="System.Net.Http.Json" Version="5.0.0-rc.2.20475.5" />
As WASM runs in your browser you should clear the applications cache as well, between dll changes.
                The reason I tried updating in the first place was to solve the problem. I reverted back to 3.2.1, nothing changes. Problem remains.

Adding to @enet answer for future similar cases, it requires to define local variable like this, otherwise it is a circular reference which eventually lead to out of memory issue:
    private string _Name
    public string Name
         //...
         return this._Name;
         this._Name = value;
         //...
