SOAP api usually returns SOAP 12 but sometimes SOAP11

[MaximKitsenko]

I add magento 2.1.0 SOAP api service reference to C# project. I use
POST https://www.xxx.com/soap/default?services=salesOrderRepositoryV1 trying to get orded by id. If orders exists respons is SOAP 12 but if there is no order response is SOAP11

Preconditions

1. Magento 2.1.0.
2. C#, WebService reference generated by Visual Studio

Steps to reproduce

1. request:

POST https://www.mymagento.com/soap/default?services=salesOrderRepositoryV1 


<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/"><s:Body><salesOrderRepositoryV1GetRequest xmlns="https://www.mymagento.com/soap/default?services=salesOrderRepositoryV1"><id xmlns="">432</id></salesOrderRepositoryV1GetRequest></s:Body></s:Envelope>

Expected result

1. this is an example of response where magento order exists. Response is SOAP 12. Response body starts from

<?xml version="1.0" encoding="UTF-8"?>
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns1="https://www.mymagento.com/soap/default?services=salesOrderRepositoryV1"><

Actual result

1. Response is SOAP 11. Response body

<?xml version="1.0" encoding="UTF-8"?>
<env:Envelope xmlns:env="http://www.w3.org/2003/05/soap-envelope" >
   <env:Body>
      <env:Fault>
         <env:Code>
            <env:Value>env:Sender</env:Value>
         </env:Code>
         <env:Reason>
            <env:Text xml:lang="en">Requested entity doesn't exist</env:Text>
         </env:Reason>

      </env:Fault>
   </env:Body>
</env:Envelope>

UPDATE:

Another strange thing - is that really this order exists. I received this order 432 from GetList API function

Have you tried with REST API?

[MaximKitsenko]

I have already implemented SOAP wrapper for magento SOAP API and i want to make sure there is no another way to force magento to work via SOAP before looking into REST

@veloraven any updates?

I have another example:

<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">
    <s:Body>
        <catalogInventoryStockRegistryV1GetStockItemBySkuRequest xmlns="https://mystore/soap/default?services=catalogInventoryStockRegistryV1">
            <productSku xmlns="">qwerty
            </productSku>
        </catalogInventoryStockRegistryV1GetStockItemBySkuRequest>
    </s:Body>
</s:Envelope>

respnse:

<?xml version="1.0" encoding="UTF-8"?>
<env:Envelope xmlns:env="http://www.w3.org/2003/05/soap-envelope" >
   <env:Body>
      <env:Fault>
         <env:Code>
            <env:Value>env:Sender</env:Value>
         </env:Code>
         <env:Reason>
            <env:Text xml:lang="en">Product with SKU &quot;%1&quot; does not exist</env:Text>
         </env:Reason>         
      </env:Fault>
   </env:Body>
</env:Envelope>
