Hi Jose luis Barajas,


We prepared a Blazor WASM sample by rendering Sidebar in the 20.1.0.50 version which is working fine. We suspect that this issue might be specific to your application. Refer to the following blog for more details on this issue.


https://github.com/dotnet/aspnetcore/issues/19814


Here, we are attaching the sample for your reference.


In addition, we like to know whether you are using the .Net 6 framework. If possible, kindly modify the attached sample to replicate the issue so that we can serve you better.


Regards,

Keerthana R

Hello,

i can confirm as well, same issue using for example 2 DataGrid with 2 tabs, each tab is responsible of loading Datagrid, then not always but quite frequently a crash occurs mentionning 'DotNetObjectReference'...
