True, but then I would be processing a Huge data set and would be using something a little more complex that would allow for parallel processing of the data. Possibly Sort and Scan for duplicates. That would require the items to be Comparable as well as Equatable.

Why use a List<String>? How about just creating an anonymous object with the properties you want, or even use a class with the properties you want?

You too.
An empty iteration statement (the third part) is a valid expression. This can be zero or more expressions separated by the comma operator, and don't have to do anything related to the termination condition.

Then you are probably trying to implement and divide-and-conquer algorithm for your Algorithms and Data Structures course.
When I took it, we had to calculate 72!, which has 100 digits. I had to do it in Pascal.
The trick is to break it into chunks that you can add or multiply, do the operation on the chucks, and then recombine them into a structure that can hold the result, possibly an array.

Don't you mean string requiredFormat = "yyyy-MM-dd";?

Actually, the question lacks the context of seeing the time metrics during debugging.
VS has a lot of features that change depending on what you are doing.
I suggest that you edit your question to make it clearer where you expected the metrics so that others can understand you problem and benefit from the answers.

True enough. However, Console Apps work fine, as the output gets thrown away. Just don't try and read from the Console :)

Despite the fact that the async/await pattern was specifically created to address the complexity and non-scalablity of Threaded programming for IO bound code?
Matthew Dennis 15-Jul-14 13:41pm View
   
You obviously don't understand how Async works. When an async method awaits a Task, the Thread is made available for use for the execution of other Tasks. This means that each Thread will execute multiple Tasks and will scale better. If you just spin up a new Thread for each chunk of work you will end up creating and time-slicing a large number of threads, each of which has an overhead in terms of memory and CPU.
This is shown in MS examples that have a web site using 5000 Threads for a certain level of concurrent user access, while the async version of the same site will only need 50 Threads and a lot less memory/CPU making the system much more scalable.
I personally find the async/await code much easier to write and read, but it does take a certain level of study and experimentation until you reach the 'Eureka' moment and it all makes sense.

Thanks, looks like I've got some more code reading to do. Might be a bug in the caching that is affecting determining whether the user has permitted emails and if their email address is confirmed and the confirmation has not expired.

In order to map business requirements to BDD test I will be using SpedFlow. This is a free extension for VS. Each test project needs to load the Nuget SpecFlow package to get the required dll.
It looks like Selenium is the UI automation test tool of choice. I had thought to use WaitN, but it appears to no longer being actively developed.
A Nuget package, FluentAutomation supports both Selenium and WaitN, and simplifies writing the tests.

Traced the code, and it seems to be working correctly.
Check members' Email Enables and Email confirmation dates that reported the issue and they seem correct.
This could mean that the UserPreference data is incorrect either in the cookie, session, Redis, or database. I don't think it is the email server as there are reports of Emails but no Notifications.
Need to check if there is a multi-threading issue.

Currently Article Edit Locks are maintained in the database in the Article table using the EditLockGained (DateTime?) and EditLockMemberId (int?) fields.

Unfortunately, the checking for the lock occurs in the code, not the database which can result in multiple users thinking they have the lock.
One of the reasons why the check is done in the code, is that the time stored is the time the lock was taken, not the time it should expire.

The current flow is

1. Is the article locked by someone else?
1. Set the article fields to Now and the EditorMemberId without checks.
1. Do stuff, possible over several Requests.
1. Release the lock, again without checks for ownership.

Issues

1. Because the check for locked is done using the current copy of the article, multiple users may see the article as unlocked.
1. Because of (1) multiple users will lock the article, last man wins but the others think the won.
1. Either by bad code, or because they erroneously think they have the lock, anyone can release the lock when the don’t own it.

Recommended changes:

1. Store the DateTime the lock expires DateTime so the stored procedures can check for expired lock.

1. Instead of using art_ArticleUpdateLockInfo stored procedure
UPDATE Article
SET EditLockGained = @EditLockDate, EditLockMemberId = @EditingMemberId
WHERE ArticleID = @ArticleID

or create new art_ArticleGetLock stored procedure
UPDATE Article
SET EditLockExpires = @EditLockDate, EditLockMemberId = @EditingMemberId
WHERE ArticleID = @ArticleID and
((editLockMemberId is null or editLockMemberId = @EditingMemberId) or
(editLockExpires is null or editLockExpires < GetDate()))

Success can be check by the number of records updated == 1

1. Similarily, an art_ArticleReleaseEditLock should be
UPDATE Article
SET EditLockExpires = null, EditLockMemberId = null
WHERE ArticleID = @ArticleID and
( editLockMemberId = @EditingMemberId or editLockExpires < GetDate()))

Success can be check by the number of records updated == 1

NewsletterRss.Aspx filters articles votes>=3 and rating >=3.0.
Showcase articles don't show the rating control, but surprisingly do show the Reporting flag. This means that the article will never be sent as content.
Additionally, only the top 20 articles, ordered by Popularity are selected.

API/Authentication/Register was incorrectly returning and error of 'invalid operation' where the email was new, but the username was a duplicate. This was traced to an invalid assumption in the UserRepository.UserNameAvailable method which assumed that if UserProfile did not exist in the cache, it didn't exist.

Not so. The current implementation can use any unique string as an ItemReference. However, if it is in the format of site.objectType.Id, the additional information is parsed and saved. I think the issue is that other services are assuming that the siteId, objectTypeId, and objectId exist and are using them to join tables rather that having a GlobalItemId.

I used an array of ints of 5 digit length as the product would be 10 digits or less, the max on the machine we were using. Then iteratively multiplied the array by the each number and 'normalized' the array items to 5 digits. See my alternate below on using the BigInteger class.
