Created SqlGeography.Point it works fine without problem, only creating reading inserting polygon due it throws error.
I managed to resolve this exception by downgrading Microsoft.SqlServer.Types to version 14
I get the following error :

I have this problem only on x64 offices (in all versions 2010, 2013, 2016, 2019 and 365). Everythings works fine on x86 Offices.
My project is well set (x64 platform target) and uses framework 4.8.
I've tried to install AccessDatabaseEngine x64 (2010 and 2016) but i still have the issue.
I've tried the following solutions :
Attempted to read or write protected memory. This is often an indication that other memory is corrupt
Attempted to read or write protected memory
...with no luck ...
in the event viewer i get the following :

I've been here and it's quite a nightmare. On some systems, you may have to use a newer provider, such as(note the 16):
"Provider=Microsoft.ACE.OLEDB.16.0;Data source=" & pPathBDD
Something else to try,
"Driver={Microsoft Access Driver (*.mdb, *.accdb)};Dbq=" & pPathBDD
Why do I keep seeing this error?
Execution timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding.
I don't know if the problem is in the server, or in the system itself or in the web service that created. I reconfigure the server to clear the cache memory and run a test but no luck still have that problem.
This is the code where the error is tracing

this is my error
https://ibb.co/ih3aQG
Your last Sql Select Statement doesn't look ok ... isn't there a "=" sign missing? Like "SELECT * FROM AIRBILLS WHERE AirbillNo = '" & "123456" & "'", ...
Apart from that you should think about using SqlParameters for passing Parameters ...
The following simple method works well on my local machine but throws a NullPointerException when I deploy it to App Engine. Calling any method on memberVO such as getId() throws NullPointerException. I cannot understand why this works on my local network but not on appspot.com.
I have tried replacing the serializable object with primitives and strings just for test purposes but none can be passed to GAE. All become null.
I also included the exception from the logs if anyone has any idea.
Thank you in advance for any insight.

This request caused a new process to be started for your application,
and thus caused your application code to be loaded for the first time.
This request may thus take longer and use more CPU than a typical
request for your application.
This is due to a know limitation of GAE with HTTP chunked encoding (not related to Restlet).
However, Restlet does offer a convenient workaround in recent 2.1 snapshot to prevent chunking on the client-side. See details here:
http://wiki.restlet.org/docs_2.1/13-restlet/21-restlet/318-restlet/303-restlet.html
What is a common real life use for Dispatcher.DisableProcessing in WPF? Can I use it to suspend rendering and layout when I build a complex UI in code?
As per MSDN:
Disabling dispatcher processing is an
advanced method that is intended to
eliminate the chance of unrelated
reentrancy.
So you're doing some work on the same thread the Dispatcher is executing on, but you don't want it processing events whilst you do that work. I think the really pertinent point is:
The effects of disabling processing
are as follows:
* CLR locks will not pump messages internally.
If I understand this correctly, it means that you can safely lock and not have the dispatcher pump events as a result (which might cause undesired reentrancy).
I can shared a case we've encountered recently. It's from the PropertyChangedEventManager used inside WPF for PropertyChanged event handler management. We've captured the stack when the GUI is dead:
