I'm trying to invoke a basic SOAP http service using a legacy .NET 2.0 web
service reference generated proxy.

I can invoke the service, but when the response comes back in the async
callback, the application crashes. The following log entries are generated
during the crash.

D/dalvikvm( 1104): GREF has increased to 201
D/dalvikvm(  119): GC_EXPLICIT freed 994 objects / 50768 bytes in 97ms

Reproducible: Always

Steps to Reproduce:
1. Add a webservice reference
2. Use an async call to invoke the webservice
3. Invoke the End... method on the proxy inside the callback method specified
in the initial call to the webservice.
Actual Results:  
Application crash

Expected Results:  
Got a response from the webservice.

The following code is causing the issues:

/// <summary>
/// Loads the assets from the webserver
/// </summary>
private void LoadAssets()
    if (!_settings.IsValid())
        Log.V(typeof(WhereIsItActivity).Name, "Settings are invalid. Skipping
service call");

    // Get the authentication service proxy and link a new cookie container to
    // This cookie container will contain the authentication cookie gotten from
the logon call.
    var authenticationService =
ServiceFactory.GetAuthenticationDomainService(this.BaseContext); //
Instantiates the service proxy with a valid URI.
    authenticationService.CookieContainer = new CookieContainer();

        Log.V(typeof(WhereIsItActivity).Name, "Invoking authentication

        // Perform the logon call
_settings.Password, false, false,
            null, OnAuthenticationCompleted, authenticationService);
    catch (Java.Lang.Exception ex)

private void OnAuthenticationCompleted(IAsyncResult ar)
authenticationService = 

        var result = authenticationService.EndLogin(ar);

        Log.V(typeof(WhereIsItActivity).Name, "Got response from the
authentication service");

        // Check if the user was succesfully logged on.
        if ((result.RootResults != null && result.RootResults.Length == 0) ||
result.RootResults == null)

        // Construct the domain service proxy and keep the cookie container
        // the authentication cookie gotten from the logon call.
        var domainService =
        domainService.CookieContainer = authenticationService.CookieContainer;

        Log.V(typeof(WhereIsItActivity).Name, "Invoking WaarIsI domain

        domainService.BeginGetAssets(OnGetAssetsCompleted, domainService);
    catch (Java.Lang.Exception ex)
