I have .net-4.6 and when I run the tool it just reports that I have .net-4.5. This is misleading and unhelpful because it suggests I have something that is older than .net-4.5.2. Instead, it should say that it scanned “381029” and doesn’t know about it yet.

How about full, update and revision numbers. 4.6.1.69 etc.

Visual Studio 2015 tells me I have .net-4.6.01528. I think it’s also .net-4.6.1 as I can target that with VS and run such programs.

Link the .NET 4.5 Application if we can't .NET 4.5

I get "You have .NET 4.0, this is a recent version of .NET. Download an installer for the newest version .NET 4.5.". But I have installed 4.5, and VS 2012.

The .Net Checker application determined that you have 4.6 RC2 or greater on your machine. The application was not able to determine the exact version you have. Please log an issue including this information: releaseKey=393295 so we can get it exact in the future.

My box uses a new install of Win 10 Enterprise x64 and Vs 2015 Enterprise. I wonder why I'm not having 393297 then.

IE9 doesn't include .NET info in the User Agent - need JavaScript to access navigator.useragent and Ajax it to the server...

Updated to Win 10 1607 + Visual Studio 2015 Update 3

The .Net Checker application determined that you have 4.6.2 Preview or greater on your machine. The application was not able to determine the exact version you have. Please log an issue including this information: releaseKey=394802 so we can get it exact in the future.

Site still refer only to Mono on Mac, can we have update for latest Mac ..

I've just run a check and it took me a good 10-15 seconds to be sure that I did already have the latest version installed (4.6) and I'm no idiot, it needs to be immediately clear whether you're up to date or not.

I suggest something like:

Latest version: X.X
Your version: Y.Y

YOU ARE UP TO DATE

(Green box with tick mark)

or

Latest version: X.X
Your version: Y.Y

YOU NEED TO INSTALL AN UPDATE

(Red box with cross mark)

releaseKey=394254

The main title on the page needs to reflect the Users .NET Status.

Presumably

.NET 4.5 - You're up to date
Lower Version - You need to update
Unkown/No Install - Something different?

As there are copmanies that are using the js in their sites

Add mobile user agent detection, because why not.

I can’t really tell what version of .net this is. VS says “4.6.02006”. I’ve posted a question on superuser.

Hi Scott,

I am sure time proved that this code works as expected but it looks strange for me:

installedVersions = installedVersions.OrderByDescending(p => p.Value.Major)
                .ThenByDescending(p => p.Value.Minor)
                .ThenByDescending(p => p.Value.Profile)
                .ThenByDescending(p => p.Value.ServicePack ?? 0)
                .ToDictionary(p => p.Key, p => p.Value);

if (installedVersions.Any())
{
    return installedVersions.First().Value;
}

Calling First() on a Dictionary shouldn't be a deterministic way to get the largest element from a Dictionary, or do I miss something here?

http://smallestdotnet.com/?releaseKey=460805 told me to submit this issue.

Occurred after installing .NET Framework 4.7 from https://www.microsoft.com/en-us/download/confirmation.aspx?id=55170.

This thing needs some tests on JavaScript Dom. Then I have a plan to shrink it all down.

Noted "found .Net 4.5 or greater" post issue with releaseKey=394254

Currently the site treats 4.0 as the bleeding edge version, and 3.5 as up to date. Just needs some rewording.

Need to know if the .NET 4.5 detection application is what called the site up, and present the proper message from there.

See . If IE is made fatter, the buttons don’t overlap. But it seems Spartan always wants to render the buttons on top of each other regardless of how fat I make its window.

Add a bunch of UserAgent Strings from UserAgentString.com for various browsers and OS and make sure they all get the expected responses.

http://blogs.msdn.com/b/dotnet/archive/2015/12/09/support-ending-for-the-net-framework-4-4-5-and-4-5-1.aspx?platform=hootsuite&PageIndex=3 lists this as “394254 (Windows 10) or 394271 (All other OS versions) .NET Framework 4.6.1”.

I have a larger than normal setting on my font. These means I cannot see all the output.

I think you detect the font size, or just allow the screen to be made bigger, or just make the screen bigger.

Related to .NET 4.6.2 final version

Using Chrome, with .NET 4.6 installed when I navigate to site it correctly identifies .NET 4.6.

However, the Get .NET link does nothing (points href="#" which does nothing - presumably because I'm already on the latest). It'd be nice if this still points to the download location which is what I'd expect here. Or if that's not the intent, remove or disable the button if you assume that the user is already on the latest.

Looks like the download link that was broken earlier has already been fixed.

Scott - really appreciate this site and I link to it from several products. It's kind of sad that there has to be third party site to provide this though...

Is there any chance that you can get the content management people that deal with this these downloads to have some sort of summary page that doesn't change and shows the latest available versions of the major runtime versions instead of the ever-changing links that not even your specialized site seems to be able to track reliably? It should list 2.0, 3.0, 3.5,4.0, 4.5.x and 4.6 and whatever comes after in descending order, along with a short blurp about what platforms it can run on.

This is something that should be handled by the folks that manage the new versions on the MS site.

Navigating to http://smallestdotnet.com/javascript.ashx gives a 500 error:

Running locally, javascript.ashx fails due to the compiler error
“CS1501: No overload for method 'GetUpdateInformation' takes 2 arguments” on line 14 of javascript.ashx(14,25):

A:\SmallestDotNet\SmallestDotNet\javascript.ashx(14,25): error CS1501: No overload for method 'GetUpdateInformation' takes 2 arguments

It said "You have .NET 4.0 Client Profile, this is a recent version of .NET", so I was expecting a small download, when I opened the 4.5.2 web installer the site linked me to, I ran the web installer and it said "Download Size Estimate: 102MB" (the offline installer was only 66MB so I used that)

I have a suspicion that the problem is with the installer and not your site, but even if the problem is just the installer overestimating, I believe some warning of this should be mentioned on the website.

"the [online].NET Framework is only between 28 and 66 megs"

"then calculated the total size if you chose to download the .NET Framework." I'm not sure whether it was supposed to give me this size estimate, but it didn't.

I hope the GitHub issues page is the appropriate place for me to post this.

4.6 is now RTM. The registry release key is 393297.
I will work on a PR

CheckForDotNet45 asked to log an issue with this release key

Running CheckForDotNet45.exe on a box with .NET 4.6 installed took me to http://smallestdotnet.com/?releaseKey=394271 and where I was told I should log an issue:

Please log an issue including this information: releaseKey=394271 so we can get it exact in the future.

So here I am.

In case it helps, the machine has Microsoft Windows NT 6.1.7601 Service Pack 1 (64-bit version) installed.

Perhaps use NuGet?
