Is there an existing issue for this?

[X] I have searched the existing issues

Describe the bug

<InputTextArea class="form-control" @bind-Value="@Request.Model.First().Description" /> When I upgraded .net 6.0 to .net 8.0 this controller gives me the following exception.

So I had to add name="Description".

Expected Behavior

These controllers need to work same as using blazor.server.js

Steps To Reproduce

just create a property as Request.Model.First().Description and create a EditForm . Then try to load it

Exceptions (if any)

.NET Version

.net 8

Anything else?

No response

@EmpiteLakshitha thanks for contacting us.

As part of SSR support all input elements need to generate a form field name attribute, which they do by formatting the expression passed to the component (the thing inside the @bind expression).

There is limited support for the expressions that we support (we don't support method calls other than indexers) so there are two things you can do:

Provide a Name attribute explicitly that will be respected and will avoid generating a name.
Set ShouldUseFieldIdentifiers to false on the EditContext for the form.
