I have faced this issue too.
When we compile with Platform:x86 switch then the application runs on 32 bit host instance not the 64 bit host. Then we can not get the advantage of 64 bit.
Only option that I found to use the below . Hope this will help you
// Query for the BizTalk Receive Location.
private const string queryCom= “SELECT * FROM MSBTS_ReceiveLocation”;
string receiveLocationName = string.Empty;
//Create the WMI search object.
ManagementObjectSearcher Searcher = new ManagementObjectSearcher();
// create the scope node so we can set the WMI root node correctly.
ManagementScope scope = new ManagementScope(“root\\MicrosoftBizTalkServer”);
Searcher.Scope = scope;
// Build a Query to enumerate the MSBTS_ReceiveLocation instances if an argument
// is supplied use it to select only the matching URL.
SelectQuery selectQuery = new SelectQuery();
query.QueryString = queryCom;
// Set the query for the searcher.
Searcher.Query = selectQuery;
// Execute the query and determine if any results were obtained.
ManagementObjectCollection queryCol = Searcher.Get();
//Get the Recive Location Name from InboundTransportURL property
foreach (ManagementBaseObject envVar in queryCol)
{
PropertyDataCollection envVarProperties = envVar.Properties;
foreach (PropertyData envVarProperty in envVarProperties)
{
if ((envVarProperty.Name.Equals(“InboundTransportURL”)) &&
(inboundAddress.Equals(envVarProperty.Value)))
{
//Set the reciveLocationName from the InboundTransportURL property
receiveLocationName = envVar[“Name”].ToString();
break;
}
}
}
