Don't worry. Not everyone knows it...

As part of assignment, I was working on a project, which is having 137 projects Windows Form in a solution. Whenever I was building my solution, I was getting Out-Of-Memory error and due to this my Visual Studio use to get crash. Then the only solution left with me was to restart my Visual Studio  L . Earlier I as facing this issue once a while, but from last week, it is occurring frequently. Hope you can imagine, how painful it is restart the Visual Studio every now-and-then, especially when your solution contains such a huge number of projects. My error was something like this: “ The "ResolveManifestFiles" task failed unexpectedly. System.OutOfMemoryException: Insufficient memory to continue the execution of the program.”   The only thing, which was coming into my mind, was that it is due to Visual Studio’s memory limits. I also tried to minimize Visual Studio, but no luck :( . After consulting with few people, I got an idea to breakup my solution into multiple s...

Background Continuing to my   Prism series 1 of n , in this series, I am going to talk about a few more interesting concepts like Modules and Views. Modules In this article, we will talk about how to take other views/logic and broken down into a small pieces called Modules and use them in your Prism application. We gonna start-up by talking about What a Module is, then registering Modules, loading Modules and then we will talk about how to initialize a Module. What is a Module? You can think Module as a building block for our Prism application. It is a package that contains all the functionalities and resources required for our application. Prism provides a support for run-time Module management in our application, in which each Module can be developed and tested independently. Prism application loads the Modules as and when they are required. Before moving forward, let’s have a look at how our application was architected inside Visual Studio prior to the concept of Mo...

Introduction  Prism provides the guidance to create composite applications and help us to design loosely coupled components, which can be integrated and developed in seamless manner. Like every other application, Prism application also need to get start from somewhere. And when coming to Prism, it is Bootstrapper and Shell. These two things help any Prism application up and running. In this article, we will look more into Bootstrapper and its process. So, gear up and let's get started... Bootstrapper So, what is Bootstrapper? Bootstrapper is the class, which is responsible for initializing our application. Now question is what to initialize? So, the first thing is to initialize is the Core Services and then the Application Specific Services. Core Services : These are non-application specific services that Prism library provide to us. These services include: IModuleManager  - Responsible for retrieving application's modules IModuleCatalog  - It is used to reg...

While doing one of my assignment, I came across a strange fact about GetHashCode() in C#. Object.GetHashCode() tells that String class returns identical hash codes for identical strings. But after doing some experiments, I found that above mentioned statement is bit misleading. Actually, it varies from architecture-to-architecture, depending upon, whether one is using 32-bit or 64-bit machine. To prove this, I created a sample application in C#. I ran above snippet on 32-bit windows machine and found below result: then I ran the same code on 64-bit machine and come up with below result : Now looking at above results, one can easily conclude about the behaviour of GetHashCode(). So, beware and think atleast twice, before using GetHashCode() for strings, as it may give different-different results on different-different platforms.

Continuing with my previous article, today I am going to share my one more experience with HPC.  Nowadays, there are lots of links available on net, which tell, how to submit a job to Azure HPC Scheduler. I also explored most of them, and found that almost all are talking about job submission from cloud premise(Front or Head node). But nowhere was it mentioned how to submit a job from outside of cloud vicinity. I came across this issue, while working on one of my assignments. After hitting my head, finally I found a way to do this. When we are talking about interaction between cloud and on-premise, then first thing come into our mind is network. Here definitely, TCP won’t work. There are few transport schemes available in Azure HPC framework. After exploring them, I found one as WebAPI and wow, that suits my requirement. I just used WebAPI as transport scheme, by modifying the name of the headnode to complete host name (i.e. <headNodeName>.cloudapp.net) and get my issu...

Recently I entered into the Azure’s HPC world and thought to share something, which I learnt from my experience as a beginner. Today is my first step towards the Azure’s HPC.  I just downloaded the sample service and followed the configuration instructions. But even after following those, I faced few difficulties during this journey. So, here I am sharing that experience only. Hope it will be useful for all newbies. I feel that below are the few points, which are directly related to the application performance. 1)       Affinity Group – While working on cloud, the first thing comes into mind is performance and throughput. And in order to gain better throughput and performance, one need to make sure that all our services and storage accounts hosted on the cloud are located in proximity, which will reduce data transfer time. So, to bring all the services and storage closer, we can keep all of them in a group. And in Azure’s term, this group is cal...
