Xamarin says "Allow Multiple Bind To Same Port only allowed on Windows". What do I do?

I'm trying to use SocketLite.PCL with my iOS/Android solution in Xamarin,
but I get the message Allow Multiple Bind To Same Port only allowed on Windows when running it.
What does it mean and how do I fix it?
EDIT:
Example code I'm using can be found here: https://github.com/1iveowl/SocketLite.PCL
I put the following code inside rotected async override void OnStart(){} of the app:
var udpReceived = new UdpSocketReceiver();
await udpReceived.StartListeningAsync(4992, allowMultipleBindToSamePort: true);
var udpMessageSubscriber = udpReceived.ObservableMessages.Subscribe(
msg =>
{
System.Console.WriteLine($"Remote adrres: {msg.RemoteAddress}");
System.Console.WriteLine($"Remote port: {msg.RemotePort}");
var str = System.Text.Encoding.UTF8.GetString(msg.ByteData);
System.Console.WriteLine($"Messsage: {str}");
},
ex =>
{
// Exceptions received here
}
);
EDIT 2:
Ok, so setting allowMultipleBindToSamePort to false stopped that error.
Now I get the error Address already in use.
However I am still curious as to what allowMultipleBindToSamePort is used for.

As you can see in the new documentation:
IMPORTANT: Please notice that the parameter allowMultipleBindToSamePort will only work on Windows. On other platforms it should be set to false
About However I am still curious as to what allowMultipleBindToSamePort is used for.
There is a good and complete explanation on this post, you can read more in the following stackoverflow post

Find out the source control state of a ProjectItem from a Visual Studio extension

I'm currently developing a Visual Studio extension. For a new feature I need to find out whether a given ProjectItem (file) was modified (has "Pending Changes" since the last commit). For this I would like to query the source control provider.
I already tried searching all the properties of the ProjectItem but there is nothing hidden in there.
I also tried getting a service associated with source control from the Package.cs. I tried getting IVsSccManager2, IVsSccManager3 and IVsSccGlyphs. All return null (the test project is under source control). edit: I try to get these services by calling GetService(typeof(IVsSccManager2)) inside my Package.cs. The source control plugin of my debugging session correctly shows the changed files at the time this is called.
I can't seem to find anything online about this topic. How can I find out the modified state? Is it even possible?

After letting this topic sit for some time I recently came back to it and found the solution thanks to the help of my collegue. The problem was that I had no experience in bitwise comparison so I didn't know how to handle the response properly. Luckily my collegue gave me the right tip.
To interpret the result of status (thanks to #simon-mourier for the help on this code):
uint[] sccStatus = new uint[] { 0 };
if (VSConstants.S_OK == manager.GetSccGlyph(1, new[] { filePath }, new[] { VsStateIcon.STATEICON_NOSTATEICON }, sccStatus))
{
__SccStatus status = (__SccStatus)sccStatus[0];
}
One has to do bitwise comparison with the state of __SccStatus you are looking for, for example:
if ((sccStatus[0] & (uint)__SccStatus.SCC_STATUS_RESERVED_2) != 0)
return true;
The comparison returns true in case the state is set. If you need help on what specific state combinations can mean, just comment here and I can help on that.

Get Direct Reports from Logged in user from Exchange

I need to get the direct reports from a logged in user (MVC 4)
I don't need the names of the direct reports but I do need their email addresses including their proxy addresses.
So for this reason I need to search through Exchange. I personally have never attempted to search Exchange in the past and everything I find out there tells me how to get from step 8 to the finish line but says nothing about how to go from step 1 to 8.
I can get the current users user name by simply
User.Identity.Name.Replace(#"yourdomain\", "")
and I have found this example which so far is probably the best example I have found
http://msdn.microsoft.com/en-us/library/office/ff184617(v=office.15).aspx
but even with that example the line
Outlook.AddressEntry currentUser =
Application.Session.CurrentUser.AddressEntry;
is not actually getting the current user logged into the site.
I really hope someone out there is familiar with this and can get me past this point.

I reworked the sample from the URL as the following LINQPad 4 query. I've found that LINQPad is a great way to experiment because it is very scripty, allowing quick experimentation, and you can easily view data by using the Dump() extension method. Purchasing intellisense support is totally worthwhile.
Also, I noticed there is a lot of fine print like:
The logged-on user must be online for this method to return an AddressEntries collection; otherwise, GetDirectReports returns a null reference. For production code, you must test for the user being offline by using the _NameSpace.ExchangeConnectionMode property, or the _Account.ExchangeConnectionMode property for multiple Exchange scenarios.
and
If the current user has a manager, GetDirectReports() is called to return an AddressEntries collection that represents the address entries for all the direct reports of user’s manager. If the manager has no direct reports, GetDirectReports returns an AddressEntries collection that has a count of zero.
So there are a lot of assumptions like Exchange is configured properly with Direct Report relationships, and the current user is online...which I believe brings Lync into the equation. Hopefully this LINQPad query will be useful to you. Just copy and paste it into a text editor and name it with the .linq file extension. You'll then be able to open it in LINQPad 4. BTW: You're question caught my attention because there was talk recently at my work of pulling direct reports from Active Directory. I wish I could be more helpful...good luck.

manager.Dump();
if (manager != null)
{
AddressEntries addrEntries = manager.GetDirectReports();
if (addrEntries != null)
{
foreach (AddressEntry addrEntry in addrEntries)
{
ExchangeUser exchUser = addrEntry.GetExchangeUser();
StringBuilder sb = new StringBuilder();
sb.AppendLine("Name: " + exchUser.Name);
sb.AppendLine("Title: " + exchUser.JobTitle);
sb.AppendLine("Department: " + exchUser.Department);
sb.AppendLine("Location: " + exchUser.OfficeLocation);
sb.Dump();
}
}
}
}
}

I would suggest using EWS Managed API in conjunction with your code to get the direct reports for a user. As Jeremy mentioned in his response that you need to have your direct report relationships already set up. To help you get started, here some steps to get EWS Managed API up and running:
Download the latest version of EWS Managed API
Get started with EWS Managed API client applications to learn about how to reference the assembly, set the service URL, and communicate with EWS.
Start working with your code. If you need some functioning code to get you going, check out the Exchange 2013 101 Code Samples that has some authentication code already written and a bunch of examples you can modify to make your own.
If you have the email address or user name of the current user you can use the ResolveName() method to get to their mailbox to retrieve additional information. Here is an article to help with that method: How to: Resolve ambiguous names by using EWS in Exchange 2013
Essentially you want to get to the point where you can run a command similar to this:
NameResolutionCollection coll = service.ResolveName(NameToResolve, ResolveNameSearchLocation.DirectoryOnly, true, new PropertySet(BasePropertySet.FirstClassProperties));
If you give a unique enough value in the NameToResolve parameter you should only get back one item in the collection. With that, you can look at the direct reports collection within that one item and see not only the names of their direct reports, but their email addresses as well.
I hope this information helps. If this does resolve your problem, please mark the post as answered.

vmware .net api help vmware.vim.dll problems

Vmware's .net api reference is somewhat confusing and hard to follow. I have been able to connect to my vcenter host then get a list of esxi hosts. Then I have been able get all the running modules on the host using HostKernelModuleSystem, and probe the properties on the variable "mod"... but I am not able to figure out how to get license info, I tried creating an object lic below, trying all different kinds of "types" from vmware with the word license in the type. but, it never works it has a problem converting the line with LicenseManagerLicenseInfo lic = .... I always get the following:
"Cannot convert type 'Vmware.Vim.Viewbase' to
'Vmware.Vim.LicenseManagerLicenseInfo'"
but the declaration above it for "mod" works fine.
I have also tried:
HostLicenseConnectInfo
LicenseAssignmentManagerLicenseAssignment
LicenseManager
I am hoping someone who has worked with vmware .net api can shed some light on what i am doing wrong? I am new to C# about 1 year :) but these VMware APIs are somewhat confusing to me.
esxList = client.FindEntityViews(typeof(HostSystem), null, null, null);
foreach (HostSystem host in esxList)
{
HostKernelModuleSystem mod = (HostKernelModuleSystem)client.GetView(host.ConfigManager.KernelModuleSystem, null);
LicenseManagerLicenseInfo lic = (LicenseManagerLicenseInfo)client.GetView(host.ConfigManager.LicenseManager, null);
string name = lic.Name;
}

I'll have to go to work tomorrow to look at this ( don't have ESX and VMWare SDK for .NET at home ) but I've done a bit of this work.
I wrote a generics method that wraps FindEntityViews and takes a filter as an argument. That makes it easy to search for anything. Also I've noticed that searches come back as ManagedObjectReferences and can't be cast to the subclasses. You have to construct them passing the ManagedObjectReference as an argument.
Also I find searching for PowerCLI examples and watching the classes in the immeadiate window very help in navigating this API. It's a fairly decent SDK but they put all of the classes in a single namespace and there's lots of little style inconsistencies ( Device instead of Devices and properties that take strings instead of enums when an enum exists ).

i figured out how to do it :) , by using http://vcenter_hostname/mob I was able to walk through api better. here is what I did, plus instead of of using "host" which was type HostSystem I jused my instance of my vCenter host "client"
VMware.Vim.LicenseManager lic_manager = (VMware.Vim.LicenseManager)client.GetView(client.ServiceContent.LicenseManager, null);
LicenseManagerLicenseInfo[] lic_found = lic_manager.Licenses;
foreach (LicenseManagerLicenseInfo lic in lic_found)
{
string test = lic.Name.ToString();
string test2 = lic.LicenseKey.ToString();
}

Sharepoint List webservice error on CheckoutFile method with SSL

I am trying to checkout a file from a SharePoint document library before downloading to my client application for edit.
//documentPath = https://192.168.1.10/Utility/Phys/Document%20Library/document.xml
//listWebServiceURL = https://192.168.1.10/Utility/Phys/Document%20Library/_vti_bin/lists.asmx
private void CheckOutFile(string documentPath)
{
string listWebServiceUrl = this.GetListServiceURL(documentPath);
bool checkedOut;
using (Lists listWebService = new Lists())
{
listWebService.Credentials = CredentialCache.DefaultCredentials;
listWebService.Url = listWebServiceUrl;
checkedOut = listWebService.CheckOutFile(documentPath, "true", string.Empty);
}
}
When the checkedOut = listWebService.CheckOutFile(documentPath, "true", string.Empty); line runs I get a SOAPServerException.
((System.Xml.XmlElement)((System.Web.Services.Protocols.SoapException)(ex)).Detail).InnerText
Object reference not set to an instance of an object.
Any help on this would be appreciated.
Thank you,
Keith
EDIT:
I have tested the above code against a SharePoint library that does not use SSL and it seems to work fine.

Maybe this is an alternate access mapping problem (The "Object Not Set" error is a telltale sign)? You've got one for https://192.168.1.10/ in Central Administration->Operations->Global Configuration->Alternate Access Mappings, ya?

I believe you have to provide a time value in the last argument in listWebService.CheckOutFile. It may be complaining about the string.Empty. Try putting in a string like; "12 May 2009 22:00:00 GMT"

I just ran into this Object Reference error and got it to work by adding the domain to the URL.
http://servername - gets an error,
but
http://servername.domain.com - checkout worked
Makes sense that by being fully qualified it's clearly in the intranet zone for alternate access mappings.
