            Return inline dynamic SVG from MVC Controller
            Asked 2022-Mar-11 at 11:50

            I'm building a method on my Controller to generate an SVG QR Code (QRCoder) and I'm trying to inline the resultant SVG from the controller into the View using a Method on the Controller.

            When I attempt to view the method directly, I see the SVG XML coming back successfully, but it's getting an exception. I'm not quite sure what I need to make my controller return so that I can do this in my view.

            Turns out to be very simple to solve. Just needed to return Content instead of File

            One thing that strikes me is that you copy the .csproj file into a /src/src directory which seems wrong. You're aleady in the working directory /src and then you copy the file into a src directory below that. Try changing these lines in your dockerfile

            Is it possible to append a string in code to a Base64 string and create a new Image with the string?
            Asked 2021-Sep-08 at 15:21

            I am using the QR Coder library in C# to generate QR codes that will go to a URL with a Token in the Query String. https://github.com/codebude/QRCoder

            Currently, I can Print Preview all the QR Codes, but without a Token showing beneath it.

            I need to display a string below the QR Code image with a Token Code when I click on the Print Preview button. This will fetch all the QR Code images and show them on the Print Preview window.

            The Print Preview button will fetch all the Tokens generated, append them to a link and finally generate the base64 string for the QR Image that is sent to a JavaScript Print method.

            I am using Print JS: https://printjs.crabbly.com/

            The base64 value you provided in your question is malformed, my recommendation is to not use Json Serialization for this Api response effort.

            Try using Convert.ToBase64String

            • Ensure the method returns string
            • and the jQuery request accepts/expects text for dataType response.
            Diff in your Api Endpoint

            "I have one Server project" is a little unclear since we can only see . I assume you want ot convert form a Blazor Server App to a WebAssembly app?

            The project type is now WebAssembly but you are including, amongst others,

            You can't access a database from a browser app directly. It's not supported and it wouldn't be safe (all clients would have access to the connection string).

            This project needs to be split into a Client and a Server (API) part.

            Your best course is to create a project (in a temp folder) from the full Blazor Wasm + Asp.Net Hosted + Individual Accounts template. It'll give you a complete reference for what goes where.

            Does support the framework.net 3.5 default value in the method

            The .NET Framework supports optional parameters in version 3.5 (in terms of the attributes being part of the framework), but the C# 3 compiler (which is what Visual Studio 2008 uses) doesn't. Optional parameters and named arguments were introduced in C# 4.

            I would strongly recommend using a modern version of Visual Studio, even if you still need to target ancient versions of .NET. (I'd also strongly recommend moving off unsupported versions of .NET if at all possible.)

            Images not shown in CarouselView on first load
            Asked 2020-Jun-05 at 07:48

            The scenario is, a content page is opened with a carousel displaying multiple images. The images are bound as an observable collection of ImageSource and they're fine When the page is displayed, I can see the carousels empty.

            I have tried with two different CarouselView. The one that xamarin brings by default and the one from CardsView nuget library. With both of them the result is the same.

            The page shows the carousel views without the image, but with the right amount of items (i.e: I can see that the observable collection has 3 items).

            I suspect it must be some kind of racing condition because as soon as I force a hot reload of the view while debuggin (ie: I save the XAML and the view reloads in the device) I can see the carousels with the images displayed properly.

            To reproduce it I have also added the images separately outside the carousel to prove that they're there. I've also added both carousels to the view. This is the result on the first load:

            and after I save the xaml (without doing anything on it at all) and the view refreshes, this is what I see, and it's correct.

            Notice how in the first load, the 3 images are displayed correctly outside the carousel, but not inside any of the carousels, although there is no problem if what I add in the carousel is text.

            Any idea where may be the issue? Is it a racing condition? Or is it a problem with both different carousels?

            This is my code
