Nice Article. I am trying to use the method you mentioned here in one of my project. Instead of xml files, in my case I would like to serve .pdf files in MVC pipeline. I have created a handler like below

And I have created a folder named CommonFiles inside the route directory and copied few pdf files there for testing. But the issue is when ever I try to access those files I am getting an internal server error , Its not even going through the MVC pipeline. If I just give a path which is not exists with a .pdf then its trying to go via MVC pipeline. Can you please hep me here ?

I have a custom made desk - I bought a standup desk frame and then put my own desktop from the same planks used in the Bamboo flooring as the desk top. Size wise it's a little wider than standard size but not much. Monitor space isn't a problem.

However, I ended up movable arms for the monitors (https://amzn.to/2Kz4T4m which work great) and also got rid of the 40" screen and replaced it with another 32" (same as the other). I'm actually much happier with the 32" screen as my over visibility is much better and I can be closer. After initial discomfort for 'downsizing' size change, now the smaller size seems perfect.

Hi Rick,

Great post, thank you for sharing your experience. I've been looking for a solution like this. My searches usually end with "virtualization" hits vs running both OS's side by side. I'm currently using one 40" monitor and juggling wires between systems, so I'm excited to try this solution. Silly question... but how long and deep is your desk and do you feel like you have "enough" space? I'm ready to hit the buy button on another monitor, but wondering if I need to include a new desk in the budget.

Thanks again,

Greg

OMG you're such a nice man. After digging and searching for over two hours I finally found your blog article. I finally got rid of that mysterious folder and I thank you many times. I was nearly getting crazy 😄

@Byron - the runtimes are updated supposedly on a 6 week cycle, but they're late with the latest updates it seems.

The runtimes are always available, but latest features are only available via Canary builds and any runtime install overrides the Canary build Runtimes. So yeah, it's all confusing as hell.

Nice writeup. From what I understand as of Nov. 20,2020, version 1.0.664.37 is done and does not need the Canary build. However, the development continues, that's why you see new Previews.

@Cory - Unclear at this point. I've raised various issues around this and I haven't gotten a clear answer. I think they are still trying to figure out how the runtimes will eventually be distributed, but in the near term they have to be distributed explicitly as described in the post unfortunately.

According to the info I've gotten they won't be shipping with Edge because of size (imagine that) as it essentially doubles the install size. The discussion mentioned potentially as part of Windows updates though, but then you run the risk of out of date runtimes (which would also be a problem with Edge installs although less likely since those auto-updated frequently).

I presume the WebView2 control is only a separate runtime install during preview...it will eventually be installed with Edge once it's released, right?

@Nick - You can pass parameters, but how you handle them is up to you to do decide. There's an example in the template I show above. But it will only work if you use the command line, not in Visual Studio unless you build a more complete template project extension.

Thanks for the article. Do you know if there's a way to pass flags to control what the template includes? For example choosing between a range of unit test frameworks

@Joel - that sounds promising, but I didn't try it out. In my case it's the same application - ie. Markdown Monster invoking another instance of Markdown Monster - to launch the second instance and I would have no way to notify the first instance of the second instance before it's already calling into the old one (maybe it would work as part of the activation logic). That's a bit twisted though and be a pain to figure out a few years down the road 😄

I didn't know about this feature either. Now it comes to my mind the cases that I could use it 😃. Nice and detailed post, Thanks

@Tyler - I don't think so. Server side applications can only sent HTTP responses and the browser has to decide what to do with those. Those behaviors are therefore determined by browsers not the server.

AFAIK, the options described in this post are the ones you can tweak in regards to Windows Authentication but I don't think you can specify whether auto-login or explict login occurs.

Hello, I have a similar setup on a site that i am building and i would like for it to prompt for login everytime, regardless of browser. Is there a way to do this at the application level instead of having to configure individual browsers? I cannot find anything searching google for a solution

Thanks in advance

Tyler

Hi Rick,

Great article.

About your comment: "move to a custom account that matches the actual rights required by the application".

I'm searching for the least amount of privileges needed for an specific account to run an asp.net core 2.1 application. However i can't seem to find information about this. Any links/suggestions?

@Brian - Uh, the very first example in this post does just that?

For anyone struggling with the pre-flight CORS error not working, I found the answer on another blog. Set it to allow any headers (and any methods if you wish).

services.AddCors(options =>
  {options.AddPolicy(name: MyAllowSpecificOrigins,
  builder =>
  {
    builder.WithOrigins("http://localhost:3000")
    .AllowAnyHeader()
    .AllowAnyMethod();
  });
});

The site is here: https://www.cognizantsoftvision.com/blog/cross-origin-resource-sharing-and-asp-net-core-3-1/

Yup...

I came here for SOAP but i was so surprised to see a real & authentic Soap of Kerala, the Chandrika. Do you really bathe with it ?

i spent 2 days on trying to redirect subdomains in core 3.1 digging thru posts on stackexchange and then found this post and had it working within 5 minutes. thanks huge. donation on the way

Good stuff. Nice presentation. Rick, I have a new application windows 2019 server that's been running two Blazor WASM client/server solutions under aspnet core 3.1 (hosting bundle). I've since updated dev solutions to use aspnet core version 5. Is it ok to leave the 3.1 server hosting bundle, or would you recommend I uninstall 3.1 first? Many thanks

I have tried SO Many things and None of them worked until I found your article.

Pesky files Gone! Thank you!

Rick, Thanks again for another easy and informative post. Don't want to clutter your comments section but thanks! will paypal you some monies for some new board wax :p

@Mac - it doesn't matter if you have it enabled, it'll work with Managed code enabled. In fact, you can run both managed and one .NET Core app in a shared App Pool (I actually did that by accident) and it works.

The reason it's recommended to not have it on is that if on the managed pipeline is loaded which adds a small amount overhead and memory usage. If you're purely running Core there's no need to have that on.

Probably minor but in your IIS app pool settings I think ANCM2's recommended .NET CLR Version should be "No Managed Code"... which I only noticed because I was running one dev box with the default ".NET 4.0" recently, too -- I didn't see any difference but I'm pretty sure I read it somewhere recently in the docs.

thanks a lot for the input, i had 6 seconds for the connection and with the activation of TCP/IP i'm down to 0.01

Hi Rick,
Thank you very much for this post, it gave me the courage to tinker around it 😉
Have you tried removing the need of using the outputPath variable and directly defining it to point the tested project appsettings with:

string outputPath = Path.GetDirectoryName(Assembly.GetAssembly(typeof(KavaDocsConfiguration).Location);

This should allow you to avoid having to copy the appsettings.*.json files.
Even if they quickly become stable, it's still a pain to have duplicated info.

Hope this helps, thanks again !

Not as lucky here... since binary serialization is obsolete, I chose to rewrite that part (that was easy, but had also to migrate thousands of entries from binary to json) and had also some issues with the DateTime breaking change... but overall, no biggies

Hello, please fix the small letter 't' in

<httpErrors existingResponse="Passthrough" />

Should be

Came here to read about pain with .Net Upgrade, but got nothing but good news. Bonus: Angular upgrade from 9 to 11. I have an Angular Dynamics CRM toolkit that is at 9 and was thinking of upgrading to 11, but dreading the pain (last upgrade to 9 went smoothly, but remembrance of past headaches was holding me back). I'll try sometime today or over the Thanksgiving holiday.

Old post but I recently ran across it and also had the issue with the site not restarting on deploy. Looking around for different solutions I found that you can actually restart the app pool using webdeploy as well:

msdeploy.exe -verb:sync -source:recycleApp -dest:recycleApp="MyAppPool",recycleMode="RecycleAppPool",UserName='Administrator',AuthType='Basic',ComputerName="https://myserver:8172/msdeploy.axd?site=MyApp",Password=mypassword -allowUntrusted

Msdeploy is installed by visual studio at C:\Program Files (x86)\IIS\Microsoft Web Deploy V3

Perhaps someone will find this useful 😃

@Igor - if you use IActionResult Swagger can't determine the type of the data you're returning. It works but the type information won't be available.

I see how to remove a file, but how do I remove a FOLDER? We have a TypeScript folder in our project that has 10 files and 14 Subfolders. Each subfolder has files and folders as well. If I could just tell VS2019 to exclude Folder "TS" from the build, that would save LOTS of time!

Hey Rick, thanks for the article! In one of your comments you mention issues with IActionResponse when using Swagger ("That has consequences like not being able to easily use Swagger.") Could you elaborate? I use both in my APIs and was curious about the issues you're running into. Thanks!

I saw a new CSS feature supported in Firefox 83 and thought it might be interesting. It is a conic gradient:

Firefox 83 adds support for conic gradients in CSS, helping colors to smoothly transition as you spin around the center, rather than as you progress outward from the center.

I assume you can punch out the middle and make an animated hourglass with it.

Firefox 83.0, See All New Features, Updates and Fixes

Just in case someone faces intellisense issues after migrating a project to VS2019 or after a VS update. See here.

Analyze > Build and Suppress Active Issues is a very helpful thing 😉

Hi Rick,

Hello from Canada.

WOW! Thanks for this. In one of our VFP9 products we use a third party HTML control to display maps. We have struggled with this problem for years (IE compatibility mode warnings).Your suggested solution solved all our issues. Finally! Thanks so much!

This is a great class! I have added two things.

1. Some people use custom background colors which make custom colors unreadable

         /// <summary>
        /// For guys who do not like the color scheme make it possible to turn it off
        /// </summary>
        public static bool EnableColor
        {
            get; set;
        } = true;

and then in the various places added the check:

        public static void WriteLine(string text, ConsoleColor? color = null)
        {
            if (color.HasValue && EnableColor)

2. When pressing Ctrl-C/Break switch back to the initial color (most of the time) to prevent cluttering up the console output after our program has exited

      /// <summary>
       /// Default color 
       /// </summary>
       static readonly System.ConsoleColor InitialForeColor = System.Console.ForegroundColor;

       static ColorConsole()
       {
           CtrlCHandler.Instance.Register(Console_CancelKeyPress);
       }

       private static void Console_CancelKeyPress()
       {
           EnableColor = false; // other threads might still be printing after we have reset the console color
           Console.ForegroundColor = InitialForeColor;
       }

Thanks Rick, this is really helpful and provided the solution to my problem, actually I read your blog quite a lot and I have found many solutions to problems I come accross on your blog!
I am using Blazor, I have a UI project and a Api project, I am publishing my UI project to the wwwroot of another "Publish" project and serving the Blazor dlls as static files.

One knew puzzle. I noticed that the new .Net 5 is generating .br and .gz files.
How do we check the accept-encoding header and return the .gz version of the file if it exists?
I tried the following but the file.context is read only:

            app.UseStaticFiles(new StaticFileOptions
            {
                // add the mimemappings
                ContentTypeProvider = extensionProvider,
                OnPrepareResponse = content =>
                {
                    if (content.Context.Request.Headers.ContainsKey("accept-encoding") &&
                        content.Context.Request.Headers["accept-encoding"].Contains("gzip"))
                    {
                        var path = content.File.PhysicalPath;
                        path += ".gz";
                        if (File.Exists(path))
                        {
                            content.File = new FileInfo(path);
                        }

                    }
                }
            });

@William - CSS changes will not immediately show - you need to hard reload the page once before CSS changes show in Chromium browsers. Due to the cache logic in Chromium (and other browsers too I think). After the one hard refresh, CSS changes will show up as you make them... weird behavior but apparently this is by design.

Update to previous comment:

I change my folder to monitor from

"FolderToMonitor": "~/../"

to

"FolderToMonitor": "~/.."

I also restarted my browser due to any update so one of the two fixed it.

When you got your signature certificate, what personal information did you provide? I would like to use my company information only, and not my personal information.

Hi Rick,

Can I use it in my WCF service the client need the response to be gzip encoded and should I place the HttpCompression code after each response (multiple scenarios for failure and success) or just one time before creating the response and sending it.

response = new Basic_Response { code = "0", message = "Auth Failed", data= null, success= true };

                HttpResponse Response = HttpContext.Current.Response;
                string AcceptEncoding = HttpContext.Current.Request.Headers["Accept-Encoding"];
                if (AcceptEncoding.Contains("gzip"))
                {
                    Response.Filter = new System.IO.Compression.GZipStream(Response.Filter, 
                 System.IO.Compression.CompressionMode.Compress);
                    Response.AppendHeader("Content-Encoding", "gzip");
                }

Following up to Dave's answer, this can be one-lined and not require any variables at all:

(Get-WebBinding -Name "My Api" -Port 443 -Protocol "https" -HostHeader "api.my.com")
.AddSslCertificate("SSL_THUMBPRINT_HERE", "my")

The last parameter "my" will resolve to the certificate store for the local computer for the Personal\Certificates folder [typical webserver SSL installation location]. You can grab the thumbprint value by inspecting the certificate in a browser, certmanager snapin, or alternatively you can use other commands on this post/comments to get the cert via powershell and access the thumbprint as a property of it.

I saw that almost immediately, but the reason being that I got burned by something similar before.

If you use WPF's DependencyPropertyKey, it needs to be initialized before the corresponding DependencyProperty. ReSharper used to rearrange that, which caused similar errors during runtime (IIRC I filed a bug for that).

@Ignat - not that I know of, and frankly I think that would be a terrible idea as that would be an invitation for malicious code to execute.

Since they are delivered as NuGet packages, you're limited to the NuGet operation which AFAIK doesn't include code execution of any kind.

If you need templates that execute code you likely need to build for Visual Studio and use a VSIX.

Just asking : could we run custom code in our template after dotnet new is doing his job ?

Found your post through https://drailing.net/2018/04/css-quicky-fixing-flexbox-width-with-pre-tags/.

I stumbled upon the breakout problem of pre inside a parent which was itself part of a display: grid rendering using auto in grid-template-columns. Applying min-width: 0 to the parent solved the issue. So it seems the solution and underlying implementations relate to flexbox as well as to grid layouts - in Chrome at least.

For anyone running into this exception after changing DEBUG settings in the project properties. have a look at issue 16805

In short

• Close the application and VS
• Go to the solution root and delete the entire .vs folder
• Done

@Kimon - I'm pretty sure that Bonjour is required in order to sync through iTunes. I can't be 100% sure because I may have had a pre-store version of iTunes installed, but I didn't install anything special to make either iTunes sync or 5k player work.

You should check and see whether the service is installed and perhaps not enabled or started.
