Scenario: Direct Access from Silverlight to Dynamics CRM 2011 Online

 

The standard approach to our case is to host an application as a Windows Azure web site. The web site will host a Silverlight application. The Silverlight application will access a MS CRM 2011 Online and will grab a data. There is the only one weakness in this plan: CRM Online didn’t publish cross domain policy files like crossdomain.xml and clientaccesspolicy.xml. There are no tools to somehow manage this or upload the files as resources. This does mean that you are not able to connect to CRM Online using Silverlight, instead you host it within the CRM. But such scenario requires that all your visitors were registered as CRM users what is not possible for internet-facing application. Let's work around this problem.

 

 

Scenario: Access to CRM 2011 Online Organization Service from a Web Server

 

The approach with accessing CRM from a web server component requires some extra work. First, we need to provide a WCF RIA service for the Silverlight application. This service will wrap a call of CRM Organization service. Additionally, it could be used to increase the security of the application and restrict an API access.

 

 

For that scenario, it is required to have a Windows Identity Foundation installed on a server. As expected, there is no WIF installed in a cloud. So you need to add a reference on Microsoft.IdentityModel.dll (C:\Program Files\Reference Assemblies\Microsoft\Windows Identity Foundation\v3.5) in a project with parameter CopyLocal = true. The code for interaction with CRM uses proxy classes from SDK and entities classes generated by CrmSvcUtil.exe. Class DeviceIdManager is also available in SDK samples (sdk\samplecode\cs\helpercode):

 

string userName = "<windows live>";
string password = "<live password>";

ClientCredentials credentials = new ClientCredentials();
credentials.UserName.UserName = userName;
credentials.UserName.Password = password;

Uri organizationUri =
new Uri(@"https://techart.api.crm5.dynamics.com/XRMServices/2011/Organization.svc");
Uri homeRealmUri = null;
Uri issuerUri = new Uri(@"https://login.live.com/extSTS.srf");

string deviceName, devicePassword;
#if DEBUG

DeviceIdManager.PersistToFile = true;
ClientCredentials cred = DeviceIdManager.LoadDeviceCredentials(issuerUri);
deviceName = cred.UserName.UserName;
devicePassword = cred.UserName.Password;

#else

DeviceIdManager.PersistToFile = false;
deviceName = "cvrmd6i7y6fozei5renofkmt";
devicePassword = "-r~-~pe`3ecWZ+ExW3Kb%F#Z";

#endif

ClientCredentials deviceCredentials =
DeviceIdManager.LoadOrRegisterDevice(issuerUri, deviceName, devicePassword);
OrganizationServiceProxy proxy =
new OrganizationServiceProxy(organizationUri, homeRealmUri, credentials, deviceCredentials);
proxy.EnableProxyTypes();

Xrm.XrmServiceContext context = new Xrm.XrmServiceContext(proxy);
techart_growerapplication gapp = new techart_growerapplication();
gapp.techart_firstname = app.FirstName;
gapp.techart_FamilyName = app.LastName;
gapp.techart_SecondName = app.SecondName;
gapp.EmailAddress = app.Email;

context.AddObject(gapp);
context.SaveChanges();

context.Dispose();
proxy.Dispose();

 


The important notes for this code are as given below:

 

1. The exact URI for issuer in your case can be found in WSDL for Organization service under:
Hide Copy Code

 

wsp:Policy/wsp:ExactlyOne/wsp:All/wsp:SignedSupportingTokens/
wsp:Policy/sp:IssuedToken/Issuer/Address

or you can use WsdlTokenManger class demonstrated in SDK (sdk\samplecode\cs\wsdlbasedproxies\online).

 

2. The call of EnableProxyTypes is mandatory. You will receive an exception without it:
Hide Copy Code

 

The formatter threw an exception while trying to deserialize the message:
There was an error while trying to deserialize parameter
http://schemas.microsoft.com/xrm/2011/Contracts/Services:entity.
The InnerException message was 'Error in line 1 position 8997.
Element 'http://schemas.microsoft.com/xrm/2011/Contracts/Services:entity'
contains data from a type that maps to the name 'Xrm:techart_application'.
The deserializer has no knowledge of any type that maps to this name.
Consider changing the implementation of the ResolveName method on your DataContractResolver
to return a non-null value for name 'techart_application' and namespace 'Xrm'.'.
Please see InnerException for more details.

 

3. Set the DeviceIdManager.PersistToFile = false and device name and password is mandatory in order to make it working on Windows Azure. Device ID will be registered in Windows Live. Windows Azure does not support storing the user or machine level files, that is why we should restrict the storing of the Device ID. As you can see, it is only required for release environment on Windows Azure.

 

So, this scenario will allow you to implement the required behaviour.

 

Scenario: Using Windows Azure Service Bus and ACS to Interact with Dynamics CRM 2011 Online

 

This scenario allows you to use all benefits of the Microsoft cloud platform. Dynamics CRM 2011 Online has an internal support for integration using Azure Service Bus. Commonly, you can download a certificate from CRM and use it to maintain a trusted relationships with another application through Service Bus.

 

 

So, in general, this is it. The main issues will rise as always during the implementation of the solutions. But currently, Azure provides spectacular tools which allows you to deliver a solution as quick as possible and does not worry about the hosting environment maintenance and support. Azure Service Bus could be expensive for a small company, but it is a good tool for middle size organizations. I must admit that the current implementation of the Service Bus is far from enterprise level product and you should consider other available products such as MS BizTalk On-premises, Oracle Service Bus or Tibco EAI. But I expect that in two years, it will become a real pearl for integration projects.

Economics Links

Posted by david.fiore Expert Jul 9, 2014

At the core, our product harnesses market forces to solve a very real and very complex problem: how to coordinate disparate bits of knowledge into action with the goal of optimal resource allocation (resources going to their highest valued good).  There has been an ongoing debate in the field of economics and in our country as to how to answer this question.  Some would say that the solution is to have wise governors act as knowledge clearinghouses, whose job it would be to allocate resources in the most efficient way possible. This approach may be called the Central Planning approach, which in its most extreme form is socialism or communism.  Others say the knowledge is too vast and too widely dispersed for any group of people to harness it effectively for the larger society.  Instead, resource allocation happens best when free markets are allowed to flourish and autonomous individuals, acting in their own best interests, compete for resources.

Here is an entertaining video which outlines some of the big themes of both positions.

Our software, much like the world we live in, operates on the principles of the free market (The Market), with some regulation (policies, constraints) thrown in.  Just like in the real world, we would have better resource allocation if it weren't for the political constraints that hamper the free market and, we must take those political factors into account or we won't be able to act at all.

For those who would like to get an introduction to economics, I have a few resources to recommend, listed below.  I recommend taking them in order:  Try I, Pencil first.  If that whets your appetite for more, go on to Economics In One Lesson, and so on.

For those who prefer to learn by listening rather than by reading, may I suggest the Econtalk podcast.  My favorites are the ones where his guest is Mike Munger, but there are lots of great episodes out there.  Here are a few to get you started:

This one is a little tongue-in-cheek:
