Today I inadvertently stumbled into this weird problem. My Visual Studio 2012 couldn’t add new Data Source using EF 6.1.1. After spent my whole morning still unable to get it to work. I resorted to switching back to EF 6.0.0, which works. Anyway, I’ll just put the steps here for those who might be able to solve this mystery.

First, let’s look into my Visual Studio version:

Next, I’ll create a Windows Form project.

Next, I installed EF 6.1.1 through NuGet

Then, I try to add Entity Framework data source in the following steps:

I clicked New Connection button then …BAMM… Exception!

Hoping for clues, I looked into Event Viewer, but I found nothing. I even restarted Visual Studio with logging turned on, but no error logs generated.

UPDATE: I’ve reported this problem in EF’s Codeplex.

Weekend kemarin aku awali dengan adu skill FIFA 15 di Playstation-nya Marta. Hasilnya ndak mengecewakan lah :D, tapi ternyata banyak jurus-jurus yang aku masih belum bisa. Semoga dengan menaruh daftar jurus di sini, permainan kita makin meningkat kualitasnya.

Selamat menikmati dan terus rajin berlatih!

1. Practice your math for 10 seconds

Here’s a website where you can train or test your Math brain power. It’s a Math game which you can configure how difficult the game would be. The lifeline starts at 10 seconds, counting down. Every time you get a correct answer, extra seconds will be added to the clock. If you make error, a few seconds deducted from the clock. The game is over when the clock reaches 0.

2. Lockless Programming

Raymond Chen, the Chuck Norris of Microsoft, shares a number of links about Lockless Programming. In programming world, the subject of locks only surfaces once we talk about multi-threading/concurrency/parallel programming. The lock is there to guarantee that only one thread can enter the “Critical Section” of a program. In another word, lock is there to maintain the data integrity across multiple threads. So you’re saying we can achieve data integrity without locks? *third-world-kid-meme*

3. Harddisk Hacking

This hacker shows us how he hacked a hard-disk by flashing malicious code into the disk’s firmware. In the end, he can gain root access with arbitrary password. I’m not really into hardware, but I learned something. His persistence in continuously probing the disk until achieving his goal, it’s an inspiration to never give up.

4. Functional Programming, why you should master it
