I have received the following error message while using Sitecore MVC Development. Posted the resolution as it might help my fellow developers when facing the same issue.
Method not found: ‘System.Web.WebPages.IDisplayMode System.Web.Mvc.ControllerContext.get_DisplayMode()’.
Resolution: I have muted/deleted the following dll and everything started working normal ‘Microsoft.Web.Mvc.FixedDisplayModes.dll’
I was eavesdropping on one of the so called ‘Technical Elevator Conversations’
I heard “NAPA”.
Did some Googling, sorry some Binging as well and started to assimilate some of the information available on MSDN and other blogs. Fell in love instantly! What’s fascinating about this is, you could develop & deploy from the scratch a complete ‘Cloud hosted App’ via browser and mere JavaScript. You would be surprised that it took less than ten minutes for the whole thing.
I thought to keep it simple and started of creating a simple temperature conversion tool, which run on simple JavaScript and some lines of HTML. After all, the whole idea is to use NAPA and create an app. So I quickly borrowed few lines of code from W3C schools and used it in my app.
Note: There are so many blogs and MSDN articles out there explaining Napa in great detail. I just made an attempt to keep it as simple as possible, just to give you a glimpse of what Napa is all about and get some first introduction to it.
Following is what I did
Option 2:
Setting up development environment for SharePoint is easy, if you have right hardware and software and basic understanding of the configuration.
For SharePoint 2007, it was simple, the hardware requirements were basic and I managed to get it working with a laptop with simple configuration. SharePoint 2013 now supports ‘App’ development and other new features that require a lot of additional RAM and a lot more hardware. So I decided NOT TO upgrade my hardware, instead make use of Azure privileges that come with my MSDN subscription.
This blog post will guide you on how to set up your developer instance on Azure and unfortunately, does not cover configuring your developer VM step by step. If you are interested to build your VM from the scratch, please follow SharePoint 2013 Virtual Machine Set up Guide (Version 3.0) from Critical Path Training.
Note: This post assumes that you already have an active subscription with ‘Microsoft Azure’. If you don’t have one, you can sign up for a trial account or if you have an active ‘MSDN Subscription’ you can enjoy a recurring $150 credit per month that ships with your subscription. This is a great way to start and I am using my subscription for all my Azure development. You may visit Microsoft Azure Free Trial: Try Azure | Azure Free Trial
Note: All the screen captures of Azure portal are valid only during the time of writing this blog post i.e. January 2015. Microsoft is very aggressive not only adding new features to the portal but enhancing its user experience.
Step 1: Navigate to Windows Azure Management Portal
Step 2: Click the 
icon at the bottom of the screen.
Step 3: You should see the following screen with an option to add a Virtual Machine from the Gallery
Select VM from Azure Gallery
Step 4: Choose the ‘Image’ of your choice, following is what I have chosen in the portal
Step 5: Perform the following actions.
Step 6: Choose appropriate ‘REGION/AFFINITY GROUP’
Step 7: Finish the configuration
Step 8: Make sure the VM is up and running
Step 9: Download RDP file and connect to the VM
Once the VM status is ‘Running’ you can ‘CONNECT’ using the following highlighted option. Clicking on ‘CONNECT’ will download the ‘RDP’ file, double click and following the screen and log on to the VM. You should be using the same ‘Username’ and ‘Password’ you have used while creating the VM on Azure Portal
Step 9: Run the PowerShell Scripts
The VM will be shipped along with few PowerShell Scripts that you need to run, to install and configure SharePoint environment, SQL Server and all the other required software. Trust me! It can’t get simpler than this, running one script spun up the whole SharePoint environment! Neat!
You will find the below highlighted shortcut on the desktop, where you will find the script ‘ConfigureSharePointFarm.psl’, Run it!
Once you ran the PowerShell script you will be asked for the ‘localSPFarmAccountName’
and ‘localSPFarmAccountPassword’, enter these and you are all set!
Step 10: Finally, you are ready. Remember to smile 🙂
Search for ‘Central’ in the installed apps on the server and you should see the gorgeous Central Admin icon, pin it to the desktop. You are all set, Happy Programming!
Note: Remember to turn the VM off, if you are not using it. Remember, you will be charged for every minute for you VM to be available and running.
