Create Custom Webconfigs in Asp.Net MVC

Image
   Here are some highlighted notes on creating a custom web-config, that I wrote after finding a very quick and easy solution to. Overall the process is very easy to get started just I felt pictures were needed because the solution I found lacked any. Start of our Application Without editing, and by default Asp.net MVC comes with a Debug and Release config but since I like to create a QA stage for my configurations with all my application another webconfig needs to be added. Now right click on the project solution and go to properties , this will bring up the configuration manager. You can also just click on the build tab shown in the second image below. Configuration Manager/Properties Under the configuration tab and inside the dropdown simply select "New" and add in your custom Config name, for this article I just name mine example. Important keep the l eave the "create new project configurations" check." If not checked you will not be able to

Asp.Net MVC Warning Msg: "Consider app.config Remapping of Assembly"

    I don't like to ignore warnings if I can help it so looking at the output window in Visual Studio I can see the following message listed in the title. I make it my goal once a project is working and completely setup to go back and clean out as many warnings as possible which in most cases I do this while I'm working. There are a lot of ways to see this warning message but one of the reasons that it appears for me is from updating packages. For one reason or another some packages aren't updating properly and the older versions are still being pointed to in one or more webconfigs.     There are two approaches I have found to solve this, one is updating the webconfigs manually which will require you to look at the packages and versions being pointed to in the webconfigs. Or you can try the using Nuget command console. Targeting just the packages that appears in the warning message, and re-installing. This sometimes will work but if that fails there is a step had to I try

Coursera: Gamification Notes II

Motivation & Psychology (I) For Gamification you need psychology to a certain degree to understand users motivation and making gamification effective. Motivation is different for everyone and can be counterintuitive.  Cognitivism  - about the mental states, internally. Behaviorism - looking externally at what people do.

Coursera: Introduction to Databases Part II

    Continuing from my previous article  this post is a collection of my notes, and my study of SQL databasing. Relational Algebra Tuple - Wikipedia sql - What does the term "Tuple" Mean in Relational Databases? - Stack Overflow sql - Clear explanation of the "theta join" in relational algebra? - Stack Overflow Two selection operators in a row can always be replaced by a single selection operator whose condition is the "and" of the two selection conditions. If there are two projection operators in a row, the attribute list of the second (outer) projection must be a subset of the attribute list of the first (inner) projection. Thus, the first projection can be removed without changing the result of the expression.

Coursera: Terrorism and Counterterrorism Notes

   The main reason for  me taking this class even though it was not related to the computer science was to gain a better understanding on terrorism and also to make any connections to related topic in the computer science like cyber-terrorism . To explain a little bit more on why I felt I should have a better understanding on terrorism draws back from my last year college. During which the summer of 2013, I meet with SUNYIT's  president. Our discussion was about collaborating with  Google Maps' floorplans . With the help from a Google Maps team, this project would allow students to find classes and events more easily while on the campus. However this motion was denied and had end on the note that terrorists would use this new technology to their advantage. I strongly disagreed with this acquisition and so I started my research on the topic using the Tags: SUNYIT, Google Maps. Questions to ask? Who would have an agenda? National?  Local? Religion? Are we on another

Installing Windows on Acer chromebook 15 cb3-532

Much of my notes are just small problems I faced (what's new!) haha. Either way this was a really fun project to do for a friend and I got excited once I research all the information. You can find instruction videos but what helped me the most was the coolstar website. Sadly they don't have parameters in the url so I can link the machine I used in this article. -  https://coolstar.org/chromebook/windows-install.html Scared of messing with the bios? Don't be!    So you need to first remove the screw to put a legacy bios on the machine. Its easy to backup the chrome os one and with the same steps to change it. You can go back in and revert to the chrome version bios. Its that last part that had me worried and its very easy to do.  Problems getting into Developer Mode?   Follow the instructions to the letter, during the step to disable the OS verification, press Ctrl-D to boot into os. If you hear two beeps I would go back to set one. I got in a loop where it s

Entity Framework: ToListAynsc & WhereAsync

When upgrading aspnet mvc applications I like to take a look on how I can convert the api's to async. This sometimes is really easy but as things get more complex my queries do as well. So this is a list of ways you can form a where clause on top your  async  but note not all solutions take advantage of it. Notes on EFCore Entity Framework Core provides a set of asynchronous extension methods that can be used as an alternative to the LINQ methods that cause a query to be executed and results returned. Examples include  ToListAsync() ,  ToArrayAsync() ,  SingleAsync() , etc. There are not async versions of LINQ operators such as  Where(...) ,  OrderBy(...) , etc. because these methods only build up the LINQ expression tree and do not cause the query to be executed in the database. https://codereview.stackexchange.com/questions/32160/filtering-a-collection-by-an-async-result Filtering a collection by an async result ,  built an extension method called WhereAsync. publ
