How to fix TFS build issue "ResolveComReference" task failed unexpectedly process can't access file System.Windows.Interactivity.resources.dll'

I have a WPF solution and I'm using Visual Studio Team Services with TFVC for source control. I've created an automated build, however, the build will fail (sporadically) with the following error:
C:\Windows\Microsoft.NET\Framework64\v4.0.30319\Microsoft.Common.targets (2015, 0)
The "ResolveComReference" task failed unexpectedly.
System.IO.IOException: The process cannot access the file 'C:\a\bin\es\System.Windows.Interactivity.resources.dll' because it is being used by another process.

When this does occur.. I can queue another build and it will pass. Does anyone know why this may be happening and how it can be fixed?

AppDomainUnloadedException when TFS is cloning git repos for a build

Suddenly, when queuing builds in TFS based on a git team project, I get the following stack trace.

I changed nothing for this to happend, googling so far I found info about it perhaps being macafee, but we dont use that on our build agent.
Using an on-premises build server
Normal TFS team projects build as expected

Resolved by restarting the server - not sure how I didn't think of that.

Exception on Serialization when making Active Directory calls

I have code in my Facade layer to make calls to active directory
activeDirectoryUserCache = new MyFacade()
.GetActiveDirectorySearchResults(MyEnum.MemberCategory.User);
This call works fine in my local machine. But when the same is deployed to DEV server, it throws the following exception.
{System.Runtime.Serialization.SerializationException: The input stream
is not a valid binary format. The starting contents (in bytes) are:
53-79-73-74-65-6D-2E-49-4F-2E-46-69-6C-65-4E-6F-74 ...

As I understand the active directory call works with the Principal Objects and I believe they are not serializable by default and I cannot mark them as they are .net reserved objects. But what should I be doing in order to get rid of this issue?
I am using System.DirectoryServices.AccountManagement; namespace for AD Get users and groups calls.

"Value cannot be null" when invoking method decorated with [Autocomplete]

I have a Windows Forms application (.NET 3.5) which is deployed with the ClickOnce-technology and is used by approximately 50-100 concurrent users. They all target the same MS SQL database (SQL SERVER 2008 R2) which is hosted externally.
The application itself uses a "wrapper"-class to perform database queries. This class derives from ServicedComponent and decorates its methods with the [AutoComplete] attribute. Below is an example:
[Serializable]
[Transaction(TransactionOption.Required, Isolation=TransactionIsolationLevel.ReadCommitted)]
public class CTxGreenfee374Processor: ServicedComponent
{
public CTxGreenfee374Processor() { }
[AutoComplete]
internal Season SaveSeason(CallContext callContext, Season season)
{
return new PGreenfee374Processor().SaveSeason(callContext, season);
}
}
Most of the time this approach works like a charm. But numerous times a day following exception occur when this method gets invoked (of course there are similar methods with this exact problem):
System.ArgumentNullException
Value cannot be null.

As you can see the method SaveSeason in the CTxGreenfee374Processor class is mentioned in the exception. As far as I can see this is the last trace of code that I've written.
My only clue is that the exception has something to do with the [AutoComplete] attribute and/or the derived ServicedComponent class. This conclusion is based on that I've checked for invalid input parameters and that no code inside the method gets executed before the exception. And I assume that both ServicedComponent class and [AutoComplete] attribute performs som kind of logic before the method block executes.
I haven't been successful in recreating this exception when debugging, due to inconsequent occurrences of this exeption. So I've had to depend on logs from the production application.
If anyone got an idea regarding this problem it would be extremely appreciated!

WCF Service TargetInvocationException - Possible Cyclic Reference

I need a little help with an Exception being thrown at my WCF service. The point is: I need to develop a WPF application and I've heard that to treat data WCF is the best choice so I used it only with basic knowledge and now I have this problem.
The point is, I have a Customer class, a Supplier class and an Order class. I have then two services: the first one has all methods to add, read and edit customers and suppliers from database. This service works perfectly fine. The second service has methods to add new orders, edit orders and read them from database, and this service has a problem.
The class Customer has a list of Suppliers (the suppliers from which the customer buys), the class Supplier has a list of Customers (the customers that buy from that supplier). The class order has a Customer, a Supplier and a list of Itens (and the itens are added to the database together with the order).
The method for adding an order works fine, however, once an order has been added, the method to list the orders throws the TargetInvocationException. I searched a lot on the internet and the best answer I've found is that it's possibly a "Ciclyc Reference".
The method to list the orders is inside the repository class and is simply:
public IQueryable<Order> ListOrders()
{
return Context.Set<Order>().Include(x => x.Customer).Include(x => x.Supplier);
}
Where Context is the entity framework context. I tried to remove the includes and load the customer and supplier separately, but the result was the same exception.
Can someone please help me ? If I need to post more information just tell me. And sorry if this matter is trivial, I'm new to WPF and WCF so I'm still a little confused.
Thanks a lot in advance.
EDIT Exception below
An error occurred while receiving the HTTP response to
http://SomeService.com/OrdersService.svc. This could be due to the
service endpoint binding not using the HTTP protocol. This could also
be due to an HTTP request context being
aborted by the server (possibly due to the service shutting down). See
server logs for more details.

Mark your data objects with the [DataContract(IsReference = true)] attribute. This should resolve the issue.
