Dynamics CRM 2016 PluginProfiler System.TypeLoadException

I'm having problems debugging my assembly using the PluginProfiler supplied with the PluginRegistrationTool. Once I mark the step as profiling and trigger it (Create an account) it shows the following error message:

I'm using StructureMap as IoC container and StructureMap.AutoFactory, which requires Castle.Core. I'm using ILMerge to merge all assemblies into a single on. I'm using the following arguments to execute ILMerge:
/target:library
/out:"$outPath"
/log:"$logFile"
/keyfile:"${keyFile}"
/copyattrs
/wildcards
/targetplatform:"v4,${Env:ProgramFiles(x86)}\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.5.2"
and the following assemblies (left out my dlls):
"${targetDir}StructureMap.dll"
"${targetDir}StructureMap.AutoFactory.dll"
"${targetDir}Castle.Core.dll"
I'm really out of ideas and it would be great if someone finds the time to help me. Thanks in advance!

As per this article the Sandboxed environment in which plugins run prohibits the use of Reflection to access internal members. I'm not familiar with dynamics proxying per se, but it looks like creating types on the fly and potentially using reflection in the process may not be possible in the sandbox.
If you have an on-prem dev environment you could register the plugin outside the sandbox and see what happens.

Serialization in Sitecore

I have a custom module in Sitecore which works fine if app pool session state is set to In process. When I change it to SQL Server I get error message saying that it is Unable to serialize the session state. All my classes I am using are serializable. My code is triggered by custom ribbon button and this error is thrown when I click on it. It is supposed to display dialog form but it shows error message instead. I thought it has sth to do with Sitecore DialogForm class which my class inherits, but it turned out that this is not the case.
When I debug the code error is thrown once Run(TranslateArgs args) method has finished executing - it is called from public override void Execute(CommandContext context) and is supposed to display dialog by calling SheerResponse.ShowModalDialog(str4.ToString(), true);
I also thought that it was because I used ClientPipelineArgs in Run method, but after creating custom class (and making it serializable) that inherits ClientPipelineArgs error didn't go away.
Any ideas what might be causing it?

Well the stack trace tells us, that some code is trying to put a Sitecore.Data.Database onto SessionState, and that won't work. It has no public constructor, but that is the very least of the problems. It can happen if trying to put an instantiated Item onto SessionState as well.
The stack trace appears to be incomplete. It should show you, which line of code in your Run method, is the root source of the exception.
What isn't clear to me; which exact version of Sitecore are you on?

Currently out-of-process session state mode is experimental feature in Sitecore. InProc is the best option for the Client. Find more details here.
If you still think that out-of-process is the right way to go, make sure you set it in accordance with this article.
[Update] Out-of-process session states are not supported on Content Management instance anymore. Link.

how to deploy a Webapi project (coupled with EF & LocalDb) to Azure

Quickly to get a feeling on azure, I created a webapi project which uses EF and Local DB and it has some crud operations.
Then I signed up to Azure, created a WebApp and then downloaded the publish profile.
Using VS 2013, deployed the application to Azure. Navigated to index.html everything is working fine.
The problem is when I try to execute a simple HttpGet (which returns the value from the LocalDB), I am getting the below stack trace.
<Error>

I also see there are no options to create a LocalDb in Azure Website.
I initially guessed since I am using CodeFirst approach, Azure will automatically create the database for me.
EDIT: I have seeded the database and added some sample data to the localdb. The api works just fine in my local machine.
Any inputs on this please ?

You should use Azure SQL Database instead of local DB.
You will still use CodeFirst.
Here is how to do it :
Enable Migrations, create the database, add sample data and a data initializer

The object with the type "xxx" cannot be converted to type "yyy"

I'm having problems calling a method from a service. The error only occurs in .NET, Java seems to work fine. Most of the methods from the service work with .NET, so far 2 of them have thrown Exceptions. The service is open if you want to try and reproduce: http://radar.zhaw.ch/services/AirTrafficWebService.wsdl
Exception

InnerException:
It is thrown in a generated Reference.cs file like this:
[System.ComponentModel.EditorBrowsableAttribute(System.ComponentModel.EditorBrowsableState.Advanced)]

}
.NET call:
AirplaneTrackingPoint[] tps = _airTrafficService.getAirplaneTrackingPoints(icao, 0, 0, false);
Java call:
List<AirplaneTrackingPoint> tps = service.getAirplaneTrackingPoints(icao, 0, 0, false).getItem();
EDIT:
The response seems to be made up out of a list containing a list of both an Airplane object and the single objects that AirplaneTrackingPoint is made of (e.g. [0] Airplane, [1] Latitude, [2] Longitude, [3] Bearing etc.). So it seems that .NET is taking the first element out of the element of the list and using that as a return value. Java seems to ignore the first element of the list in the list and instead makes an object out of the rest of the list.
Can anybody explain this behaviout?

Have you changed the service and forgot to update your service reference? Maybe earlier you returned a list of Airplane objects and some time you changed it to return your own new data structure. If you right-click on the service reference in your .NET project you can choose to update it, at which point the code that does everything for you (in Reference.cs) is recreated.
UPDATE: I can confirm that it's not working out of the box in VS2010.
I tried to run the client in .NET 4 and .NET 3.5. The first time I got some strange fault exception from the server with an SQL query string inside, now I'm only getting the cast error over and over. I followed standard VS2010 procedures to add a service reference, so there's either the service to blame or the WSDL doesn't work with svcutil (also a likely issue).
I got the following error when I changed the service reference to always generate message contracts and use these:
{"The top XML element 'return' from namespace '' references distinct types System.String and AirplaneTrackingTest.AirTraffic.Airplane[]. Use XML attributes to specify another XML name or namespace for the element or types."}
I would contact the service provider and ask for proper test parameters to their methods and if they have a reference client implementation in C#.

Hi you will need to add in a cast, presuming that the two types are compatible. You are returning an AirplaneTrackingPoints from the service and storing them as Airplanes, this sounds a little odd to me.
Your Java method calls getItem which is not present in your c# code could that be it?

Serialize ASPX page?

I am in the sitaution where I need to use an external session state server, which requires all my sessions to be serialized. I have been trying to make all the classes I store in sessions serializable, by using the [Serializeable()] attribute.
However, I keep getting the following error:
Unable to serialize the session state.
In StateServer and SQLServer mode, ASP.NET will serialize the session state objects, and as a result non-serializable objects or MarshalByRef objects are not permitted. The same restriction applies if similar serialization is done by the custom session state store in 'Custom' mode.
More interesting is however the stack trace:

The Type ASP.useroverview_aspx is as far as I know an ASPX page. The page I load is Useroverview.aspx. However, I don't try to store this page in a session. So this error makes me wonder quite a lot.
I tried to do the following in the code-behind:
[Serializable()]
public partial class UserOverview : Page
{
private static readonly int TimerInterval = HttpContext.Current.IsDebuggingEnabled ? 2000 : 750;
// ...
}
This did not help at all!
So I wonder if one could serialize an ASPX page? This don't know if this would make sense. I doubt it!
Thanks...

I found the answer.. And you guys were right: One of my objects had a reference to the page.
I had an object Player, which had a list of events. One of these events had the current page as a target, which let to the problem.
I gave the event the following non serializable attribute:
[field: NonSerialized]
Then everything worked fine. And they all lived happily ever after!
