Uploading vmdk file task failed. The error message is " System.outOfMemory"

Hi everyone,

    I performed vCloud Director SDK .net sample "HellovCloud"  to upload vmdk file, but the visual studio poped up "System.outOfMemory" message. My environment is visual studio 2010 and use .net framework 4.0 (including Microsoft.httmp from WCF REST Starter Kit). And my O.S. is Windows XP. The vCloud director version is 1.5.  The vmdk size is 1.83G.

The following code will result in "System.outOfMemory" error.

       FileStream vmdkFileInputStream = File.OpenRead(vmdkFileLocation);
       vappTemplate.UploadFile(vmdkFileName, vmdkFileInputStream,vmdkFileInputStream.Length); <-----error

Does any know what happen to cause this error? Please kindly give me a hint.

Thanks.
