Changes in net6.0 Serialization Throws Exception in SfGrid

[Mike-E]

Greetings Team Syncfusion,

I have upgraded my solution to the new `net6.0` framework and have attempted to load my Blazor server-side application with it.

It appears that the serialization mechanism has changed in .NET6, as now I am experiencing an exception thrown in SfGrid when it attempts to render:

```

 System.InvalidOperationException: The converter specified on 'Syncfusion.Blazor.Grids.GridColumn.EditTemplate' does not derive from JsonConverter or have a public parameterless constructor.

   at Syncfusion.Blazor.Grids.SfGrid`1.SerializeModel(SfGrid`1 comp)

   at Syncfusion.Blazor.Grids.SfGrid`1.OnAfterRenderAsync(Boolean firstRender)

```

Looking at the  `Syncfusion.Blazor.Grids.GridColumn.EditTemplate` it looks like such:

```

[Parameter]

    [System.ComponentModel.DefaultValue(null)]

    [JsonIgnore]

    [JsonPropertyName("editTemplate")]

    [JsonConverter(typeof (TemplateConverter))]

    public RenderFragment<object> EditTemplate { get; set; }

```

The first thing to note which I find interesting is that it is decorated with an `JsonIgnore` attribute but is still being processed.  Nonetheless, the other interesting aspect -- and the one causing the exception -- is that `TemplateConverter` inherits from `Newtonsoft.Json.JsonConverter` and not `System.Text.Json.JsonConverter`.

Somehow this is working in .NET5, but not .NET6.

If you have any suggestions on how to remedy this (especially if you have a new version compatible with .NET6 😁) it would be greatly appreciated.

Thank you for any assistance/consideration you can lend,

Michael

Wow! Thank you for such a quick reply @Rahul. I unfortunately did not see it until now as I did not get a notification.

I did try your solution (thank you so much for taking the time to make it!), but unfortunately I get the same exception:

```

Can you verify that you are using the latest RC1 SDK?

https://github.com/dotnet/installer#installers-and-binaries

I am also using Visual Studio 2022 Preview 3.1. 

The SDK version and IDE version are the only two variables that I can think of that would be the difference here.  I will continue to think of any others and post here accordingly.

Hi Rahul,

I can confirm that switching between preview-7 and rc1 (or rc2 made available this weekend) changes the behavior, with preview-7 working, and the others not.

I have filed this here:

https://developercommunity.visualstudio.com/t/net-sdk-rc-produces-exception-in-syncfusion-contro/1510479

Please feel free to add to the discussion if needed. :)

Hi,

is there any update on this? We have 2 full dev teams working on an upcoming release that are currently blocked because of this issue. It is extremely critical for us.

If it helps it seems that the breaking change has occurred with this PR:

https://github.com/dotnet/runtime/commit/91021fe27b1b845f51ff29cfd47b2405fa91b683#diff-814722ef5303e65815d350762206450b283510f6246b658047c4dffd31c97920L59-L64

Thanks you,

Enejda

[MS]

Same issue here, seems to be broken since .NET 6 RC1.

[Rahul Narayanasamy]

Hi Enejda & MiVision, 

We understand your situation. We have prioritized the issue and currently working on this with high priority. The fix will be available in the upcoming release(Volume 3) which is expected to be rolled out by the end of September 2021. Until then we appreciate your patience.

[Mike-E]

FWIW a decent workaround was posted in the bugtracker:

---

Chris commented on Sep 24, 2021 1:25 AM

@John P.

As a workaround you can install Preview 7 SDK (Net 6.0.100-preview.7.21379.14 from here: https://dotnet.microsoft.com/download/dotnet/6.0 )
Add a global.json File to the root of your project and add the following to the content:

{ "sdk": {"version": "6.0.100-preview.7.21379.14" }}

Chris

[Rahul Narayanasamy]

Hi Mike-E, 

 

Thanks for the update. 

 

If the provided suggestion in the feedback makes the application works for you, then kindly use the solution until our Volume 3 release. As we said in our previous update, the fix for the issue will be rolled out by the end of September, 2021. We will let you know once the fix is included and the release rolled out successfully. Until then we appreciate your patience.
