In basic scenarios resetting can be archived with Storage emulator UI. 

I tried this but my machine became unresponsive because due too DSService.exe and sql service.

Killing services left azure tables as they were before.

It turned out that you can also use %Azure SDK%\bin\devstore\dsinit.exe  /forceCreate command , which worked perfectly for me.

Unfortunately Azure API not supporting Contains LINQ expressions .

Contains Syntax:

LINQ

public static Product[] GetProducts(Guid[] prodIDs)

{

   return (from p in GetProducts()

where prodIDs.Contains(p.ProductID)

select p).ToArray<Product>();

}

TSQL expression  – WHERE [t0].[ProductID] IN (@p0, @p1)’,

LINQ contains syntax example has been taken from http://weblogs.asp.net/dwahlin/archive/2008/05/09/using-linq-to-perform-quot-where-in-value1-value2-quot-queries.aspx

Summary:

Default .NET HTTP connections is set to 2

Config file:  
  <system.net> 
    <connectionManagement> 
      <add address = "*" maxconnection = "48" /> 
    </connectionManagement> 
  </system.net> 

In code:  
ServicePointManager.DefaultConnectionLimit = 48; 

Turn off 100-continue (saves 1 roundtrip)

Code:  
ServicePointManager.Expect100Continue = false; // or on service point if only a particular service needs to be disabled.  
 
Config file:  
<system.net> 

    <settings> 

      <servicePointManager expect100Continue="false" /> 

    </settings> 
 
</system.net> 

To improve performance of ADO.NET Data Service deserialization name CLR Enity and table identically and use ResolveType on the

public void Query(DataServiceContext context) 
                {  
                     // set the ResolveType to a method that will return the appropriate type to creat

                     context.ResolveType = this.ResolveEntityType;   

                }  
 public Type ResolveEntityType(string name) 
 {  

                      // if the context handles just one type, you can return it without checking the   
                      // value of "name".  Otherwise, check for the name and return the appropriate  
                      // type (maybe a map of Dictionary<string, Type> will be useful) 

                      Type type  = typeof(Customer);
                      return type;  
}  

Turn entity tracking off for query results that are not going to be modified.

context.MergeOption = MergeOption.NoTracking;

Use unconditional updates/deletes

context.AttachTo("TableName", entity, "*");   
context.UpdateObject(entity); 

 Turning off Nagle may help Inserts/Updates

Code:   
ServicePointManager.UseNagleAlgorithm = false; 

Config file: 

<system.net> 
    <settings> 
      <servicePointManager expect100Continue="false" useNagleAlgorithm="false"/> 
    </settings> 
</system.net> 

private void UploadFileToBlob(string url, Asset asset,string filepath,string filename)
       {
           var container = new CloudBlobContainer(url);

           //Get a reference to a blob, which may or may not exist.
           CloudBlob blob = container.GetBlobReference(filename);
           blob.DeleteIfExists();
           //Upload content to the blob, which will create the blob if it does not already exist.
           blob.UploadFile(filepath);
       }

When I am executing UploadFileToBlob for one file it is working. On different multiple files it is throwing exception “StorageClient.StorageClientException: The specified blob already exists”.

Did some research and found out that this problem associated with multithreading in local dev storage:

“

This is a known issue with development storage. This happens when there are multiple threads launched to upload the blocks (which constitute the blob). Basically what is happening is that development storage makes use of SQL Server as the data store. Now first thing it does is makes an entry into the table which stores blob information. If there are multiple threads working then all of these threads will try to perform the same operation. After the first thread succeeds, the subsequent threads will result in this exception being raised.

“

Kind of weird, will try to investigate more to see how to resolve this issue and if size of file is really matter. Please let me know if you found any workarounds.

Few days ago I spent couple of hours trying to include all mvc references one by one making sure that application app has minimum set of required assemblies.

Phil hack published an article http://haacked.com/archive/2011/05/25/bin-deploying-asp-net-mvc-3.aspx regarding how to include MVC,Razor dependencies into your deployment.

By default Azure instance will not have required packages installed. So you need to make sure that all files will be located in your bin folder.

“If your server doesn’t have ASP.NET MVC 3 installed, you’ll need to make sure the following set of assemblies are deployed in the bin folder of your web application:

• Microsoft.Web.Infrastructure.dll
• System.Web.Helpers.dll
• System.Web.Mvc.dll
• System.Web.Razor.dll
• System.Web.WebPages.Deployment.dll
• System.Web.WebPages.dll
• System.Web.WebPages.Razor.dll

”

Simply right click on your project to add deployable dependencies.

For other GAC assemblies which are not part of .net 4.0 framework make sure to set Copy Local flag to true:

public static void RegisterRoutes(RouteCollection routes)
       {
           routes.Clear();
           var factory = new DataServiceHostFactory();
           RouteTable.Routes.Add(
               new ServiceRoute("API", factory, typeof (TestOdataService)));

It tells system to associate data service factory handler with a given URL.
