This xml file does not appear to have any style information ошибка

UPDATE: Why is it that when I use google chrome I get the error message, while when I use Windows Explorer, it will display everything fine.

I use google chrome to run my web server.
I get the following error:
I am unsure why I am getting this error, i have the files in the correct areas.

This XML file does not appear to have any style information associated with it. The document tree is shown below.

Let me try and explain what has happened:

Then i have created a cloud service just consider as (DEF cloud service).

Then i just deployed my application into that cloud service as a cloud project.

Then i enabled cdn end point for that hosted service (cloud service).

[Gaurav] In these 3 steps, you have worked with what is known as Platform as a Service (PaaS). This was something with which Windows Azure started.

Then simply created virtual machine. Suddenly one more storage account and cloud service created automatically. consider as ABC (cloud service)

[Gaurav] In this step, you ventured into something what is known as Infrastructure as a Service (IaaS). Amazon EC2 (among others) offer this. Microsoft started doing this as of last month only. When you were trying to create a virtual machine through
the wizard, there’s an option of choosing a storage account. My guess is that you opted for a new storage account and that’s why you saw 2nd storage account in your subscription.

Now coming to your questions:

i). But here what is the purpose of VM?

VM only keeps blob storage,table, querystring right. But according to my deployment my VM is just created nothing in that.

I used some tools to access my blob contents. But i am not able to get anything from tables,blobs,querystrings.? So then where are my uploaded images.

For your reference :  my uploaded images are storing into my application local folder only.

[Gaurav] Your applications in Windows Azure (whether you go PaaS or IaaS route) gets hosted in a VM. Please note that Windows Azure Storage is a separate service which offers you to store structured data (Azure Table Storage), unstructured
data e.g. files (Azure Blob Storage) and messages for asynchronous communication (Azure Queues). Under PaaS scenario, your VM is quite transient in nature i.e. it may go down anytime. If there’s anything that you store in application’s local folder, they
will be gone as well once your VM goes down. That’s why it is recommended you store the images etc. which your user uploads in Blob Storage.

ii). Here what is the difference between uploading project as website and cloud service deployment?

[Gaurav] Again, these are two different things. Windows Azure Websites are announced along with IaaS capabilities last month. My recommendation here would be to read up on what Windows Azure Websites are and how are they different than Cloud Services. In
a nutshell, Windows Azure Websites are very similar to shared hosting provided by other companies similar to Go Daddy etc.

iii). If i use websites means how can i enable cloud service for that website project and how can i enable cdn end points for that?

[Gaurav] Again, Azure Websites and Cloud Services are two ways by which you can deploy your application in Windows Azure. As far as I know, you can’t CDN enable your application. What you can do is CDN enable the content stored in Windows Azure Blob
Storage. For high availability of your applications, you would need to deploy your application across multiple data centers and load balance them using Traffic Manager.

iv). If i want to update single page means i can use ftp( websites). So only i can update single page or file. But am using cloud service deployment via VS. Then how can i update single page? I want do again a complete deployment right?

[Gaurav] If you wish to update just single pages and update your content using FTP clients, you will not be able to do so if you deploy your application using Cloud Services. You would need to deploy your application as Websites. I believe you have asked
a similar question on other thread as well.

Lastly, please don’t take this any other way but my recommendation for you would be to read up about the platform and it’s capabilities first than directly starting to deploy your application. I would recommend downloading Windows Azure Platform
Training Kit and doing the Hands On Labs there first. It would give you much better understanding of different things available to you in Windows Azure Platform. I believe it even includes some sample project about uploading images and storing them in Azure
Blob Storage.

Hope this helps.

Thanks
