Thank you for reply.
I already tried to set the key
aspnet:UseTaskFriendlySynchronizationContext to true. The result is the same : websocket doesn't want the key.
Finally I solved the problem : when reading carefully the error, it is said "Providing a non-null 'timeoutHandler' is unsupported
" which means : providing a null timeouthandler is supported...
I did that is the instruction, and it is ok now : no more error.
Dim asynctask As New PageAsyncTask(AddressOf mytask.OnBegin, AddressOf mytask.OnEnd, NOTHING, DBNull.value, false)
DAMNED : I re-use by mistake a very old account... I was a baby at this time !!!
