Ugh, this is driving me insane. Razor integration in VS has always been flaky.

VS2017 professional, Core MVC 2.0. Intellisense isn't working well in Razor files - namely, I'm not getting function/constructor parameters. Syntax highlighting works well and I'm getting intellisense for types themselves, but not for function parameters.

What do y'all like to call variables which point to Tasks?

I mean for stuff like this:

code:

var connectToClientTask = ConnectToClient();

// do some other stuff that we can do while waiting for the connection

var client = await connectToClientTask;

I tend to name then with Task on the end as I have above, but that feels a bit close to Hungarian notation which I'm not a fan of at all.

I think "task" is fine. You could also call it "runningClientConnection" or "incompleteConnection" or "attemptingClientConnection" or something that indicates that it's an in-progress activity.

"Hungarian notation" is specifically about 1. Short prefixes to indicate the type/role of a variable, and 2. The pervasive use of these on all or almost all variables in the codebase. I find it silly to dismiss all variable names that allude to the variable type in their names just because people went overboard with it in the past. Just call it "fooTask".

On the subject of Hungarian notation and Tasks, something I do find unnecessary in most cases is the overused "Async" suffix. I get the point for library code where you often have a sync/async method pair and you want to make it clear which is which, but in app code I really don't see the point. Imagine if every method that returns an IEnumerable was supposed to be called something like GetThingsLazy() instead of just GetThings(), or if every method whose return value might be null was supposed to be GetThingNullable(). GetThingsAsync() is the same thing IMO.

Is SQLDependency the right way to do server change notifications? I've got a tiny wpf app that a few people use. Originally I jammed in a timer with a check of the lastupdated datetime column every few minutes but it feels dirty.

Stuff like SignalR gets all the google search love but it seemed like more of a web thing. Using SQLDependency with entity framework returns so little in google that I really felt like I was barking up the wrong tree.

Unlikely. I would flip the question around entirely: what makes you think you need change notifications? What is the actual goal of your app?

A few people sit and work on 'orders' all day, randomly. These are shown in detail and in a grid. I don't want the user to have to do something to ensure a record they are looking at is up to date(like someone else changing a time). If it's visible on the screen, it should be relatively up to date even if the pc is completely idle.

Found this :wtf:

code in my work's codebase, figured I would share.

code:

foreach (string value in optionsObject.StringValues.Where(value => value == "SingleValue"))
{
    requestObject.PropertyValue = value;
}

Variable names changed since they're specific to this business logic, but the syntax is unchanged.

Yes, it filters down a collection to a single value, then does a foreach loop on the filtered collection, then sets a single property value on a single object to the filtered value. :thumbsup:

If only there was some sort of assignment operator to easily set a string property to an arbitrary string!

It also leaves requestObject unmodified if the collection doesn't contain SingleValue. It also invokes the side effects of PropertyValue_set (if any) once per duplicate of SingleValue in StringValues.

If there aren't any side effects you could rewrite it as

code:

if (optionsObject.StringValues.Contains("SingleValue")) {
  requestObject.PropertyValue = "SingleValue";
}

which is certainly clearer but not really smaller.

Is there anything that updating to the latest version of Windows 10 would make this code now return a different value from what it was returning a couple of weeks ago (or on an entirely different computer running Windows 7, they used to match)

code:

	Using sha512 As New System.Security.Cryptography.SHA512Managed
            Return BitConverter.ToString(sha512.ComputeHash(data))
        End Using

The windows update is the only thing I can think of that I've done recently that would cause this. If I run a project on the Windows 7 machine and then copy that exact project over to the Windows 10 machine and run them the outputs are different.

Crossposting from the C++ thread, in case some windows people here have some advice:

epalm posted:

Anyone have experience dealing with an overactive Windows Defender? It's labeling one of our programs as "Trojan:Win32/Azden.B!cl" and immediately quarantines the file.

We've done full scans on all our developer machines, no threats found, etc. I've audited the changes since our last release (a month ago) and nothing really jumps out at me as a red flag. The (C++) program is compiled using VS 2015, and packaged using iexpress.exe/makecab.exe with a bunch of sed files. A few minutes after packaging (or if we manually copy the file somewhere), Windows complains. We've since moved on to greener pastures re: packaging/deployment, but this legacy app is still being maintained.

I guess Defender just sees some "bad" bytes in our executable? I've submitted the file to Microsoft. Anything I can do in the meantime?

Fair enough, I just wrote this to test it on each system

code:

    Sub Main()
        Using sha512 As New System.Security.Cryptography.SHA512Managed
            Console.WriteLine(BitConverter.ToString(sha512.ComputeHash(System.Text.Encoding.UTF8.GetBytes(("64338F8C-4EAF-474C-89F9-15F02A760C64").Reverse().ToString))))
        End Using
    End Sub

Now, if I just pass in that GUID into both Win10 & 7, the output matches.

This is used to create some salts so it actually calls another function to garble up some of the input ("data" variable in my previous post), so to mimic part of it I added the .Reverse() part up above and this is where the output differs between Windows versions

Windows 7, VS 2015, .NET 4.5.2

code:

3D-19-F3-F9-1B-57-61-FB-F0-02-9E-41-58-EB-FF-F7-9E-28-3F-B6-83-AE-EF-0F-8E-05-4B-27-F9-DC-A0-14-0E-47-2C-6B-D8-64-BC-3B-1F-B1-67-2E-0D-7D-53-2A-E9-B5-A1-54-4B-8D-2C-EB-3F-66-C4-8F-A6-FE-3B-1A

Windows 10, VS 2017, .NET 4.5.2

code:

4C-F2-B9-FF-25-3C-1B-27-FD-D1-8D-68-66-7F-59-4F-9F-B1-5A-A0-AB-A1-77-32-8E-67-E9-D1-D8-B4-7A-C3-3B-94-46-A1-B7-2E-E2-A8-19-E2-33-64-4F-C6-2D-30-C7-B2-43-3E-15-4E-4D-2B-DB-C9-0D-16-71-7D-B6-5C

The code is identical, I just copied it from one VM to another. So it looks like the hashing isn't the issue, but something is up with what is being hashed when the string gets manipulated. Any ideas?

edit:

If I just run this code:

code:

	Console.WriteLine(("abcdefghijklmnopqrstuvwxyz").Reverse())

I get 2 different outputs

Windows 7:

code:

	System.Linq.Enumerable+<ReverseIterator>d__74`1[System.Char]

Windows 10:

code:

	System.Linq.Enumerable+<ReverseIterator>d__75`1[System.Char]

So, why is Windows 10 outputting something different? I took a snapshot before installing the updates so worst comes to worst I can roll it back, but that means I can never update that VM and I'll be stuck dismissing the nag screen to update every other day.

Oh! If you print out your "data" variable after .Reverse().ToString(), you will find the reason for your conundrum:

code:

System.Linq.Enumerable+<ReverseIterator>d__75`1[System.Char]

The call to .ToString() just returns the type of the iterator, not the value! You need to call the String constructor to actually turn it back into a string.

code:

Console.WriteLine(BitConverter.ToString(sha512.ComputeHash(System.Text.Encoding.UTF8.GetBytes(new string(("64338F8C-4EAF-474C-89F9-15F02A760C64").Reverse().ToArray())))));

I assume you do not actually want to use the type name here, of course. That would be silly.

How sure are you that data is the same between the two systems? Could there be some invisible characters (e.g. non-breaking spaces) in one of them? You could try comparing a hex dump of the two strings.

Find a third machine and see what that one does.

I literally copied and pasted from one VM to the other, can't see how something extraneous got in there.

Anyway, the problem is solved, I'm just curious why the <ReverseIterator> type returned is different between Windows versions.

NiceAaron: Oct 19, 2003; Devote your hearts to the cause~

Most likely ever-so-slightly different versions of the .NET framework.

Hell, the exact class is an implementation detail, so as long as it implements the interface it could return a different class with every call for all your code cares (or should care).

Edit: Since System.Linq.Enumerable+<ReverseIterator>d__74`1[System.Char] and System.Linq.Enumerable+<ReverseIterator>d__75`1[System.Char] appear to be the names of classes generated by the compiler for iterator blocks, it could be as simple as a method in System.Linq.Enumerable being added, removed, or moved around in the source code.

IIS is recycling the app pool. You have to keep it loaded in memory by hitting the site constantly with a script or configure IIS to only recycle if it leaks too much memory.

Is the 'MumAuthorizationRequest request' object null? The reference to request.id would throw an error if request is null.

No. It just means your synchronous API was called from some asynchronous code which is perfectly normal. The poster above has the reason for the error.

That would make perfect sense except that IDK how it could be on one server and not the other, given the same request. IIS settings shouldn't matter by then because the request got all the way into the controller code, so I guess I need to diff my local bin and the deployment directory.

A null check could be done in code before the line. At least that would confirm if it is null, before doing further investigating.

Yep, I'm sure now that the test server sees a null request object, but I still don't see why. The old test server works as expected and it works when I build locally in test configuration (and gives me the same async-style errors).

I know it wasn't a one-off bad deploy because it built and deployed overnight and it still sees a null object. One wrinkle is that I can't try the new test configuration because I can't get to that database right now because I'm working from home today and permissions are fucky on the new environment I guess, so I'll probably be back tomorrow :angel:

I just wanted to say that C# 7 is pretty cool. The problem is that now I am returning ValueTuples after using F# for awhile......

IMO returning tuples is far better than piling on out parameters, though I would probably suggest if you are returning anything wider than a triple you should probably consider creating a struct.

I'm sad that you need .NET 4.7 to use the new tuple stuff freely. I know there's a Nuget package for ValueTuple, but for Reasons^TM I can't use that, and our servers are still on .NET 4.6.x.
