I am getting a MapRequestHandler error when requesting a minified asset in release. Who is supposed to handle this request in release? Debug rendering works fine and delivers the right files.
my bundling map:
Key: "~/Plugins/Pingo.Demo.BootstrapPrimary.1.0.0.3/Content/css"
item(s): "~/Plugins/Pingo.Demo.BootstrapPrimary.1.0.0.3/Content/bootstrap.css"
,"~/Plugins/Pingo.Demo.BootstrapPrimary.1.0.0.3/Content/site.css"
Debug rendered:
<link href="/Plugins/Pingo.Demo.BootstrapPrimary.1.0.0.3/Content/bootstrap.css" rel="stylesheet"/>
<link href="/Plugins/Pingo.Demo.BootstrapPrimary.1.0.0.3/Content/site.css" rel="stylesheet"/>
Release rendered:
<link href="/plugins/Pingo.Demo.BootstrapPrimary.1.0.0.3/Content/css?v=DPgH9yYiO33UIbEOm8f4duzFsUqfKWua2il4TOVUrtQ1" rel="stylesheet"/>
The release version results in a MapRequestHandler 404 where ASP.Net is thinking this is a staticFile.
Any ideas?
Thanks
Thank you .NET Reflector for decompiling System.Web.Optimization.
System.Web.Optimization has a PreStartInitMethod, which only got called if System.Web.Optimization was referenced by my main application. In my case, I had my own PreStartInitMethod. In my version, I was calling BuildManager.AddReferencedAssembly(assembly) on a bunch of plugin assemblies. System.Web.Optimization was one of those assemblies. The PreStartInitMethod in System.Web.Optimization was not known early enough(via a direct reference), hence it was never called.
I had to find all PreStartInitMethods of all assemblies I loaded, and then call those methods from my PreStartInitMethod().
An eyeopening moment for me was that there was a lot of assemblies that I was not aware had PreStartInitMethods, so this is really a plugin 101 lesson when dealing with .NET.

I just installed Visual Studio 2019 (v16.4.3, immediately updated to 16.4.4). I have VS2017 on my system, but no prior versions of VS2019.
I created a new Blazor app project. It automatically created Index, Counter, and other pages. It created it as a .NET Core 3.1 app (as 3.1 is now installed automatically with VS2019 v16.4 and later, apparently).
I am literally following this "Get started" page:
https://learn.microsoft.com/en-us/aspnet/core/blazor/get-started?view=aspnetcore-3.1&tabs=visual-studio
I run the app with no changes from what was generated. Clicking the button on the Counter page does nothing. I don't see any messages in the Debug Output window that have any relations.
I did some searches and found reports of similar issues but the solutions don't seem to apply.
Any idea what is wrong? (it is SO annoying when a freshly generated, unmodified project does not work!)
The code for the Counter page was generated as:
#page "/counter"
<h1>Counter</h1>
<p>Current count: #currentCount</p>
<button class="btn btn-primary" #onclick="IncrementCount">Click me</button>
#code {
private int currentCount = 0;
private void IncrementCount()
{
currentCount++;
}
}
_Host.cshtml is:
#page "/"
#namespace ToDoList.Pages
#addTagHelper *, Microsoft.AspNetCore.Mvc.TagHelpers
#{
Layout = null;
}
<!DOCTYPE html>
<html lang="en">
<head>

<link href="css/site.css" rel="stylesheet" />
</head>
<body>

Update:
Per comment suggestions:
I rebooted my computer
Went straight into VS2019 and created a New Project. Selected Blazor App. Accepted all defaults. So, ended up with a project named BlazorApp1.
Hit F5 to start it up. Same results. Clicking the 'Click me' button the Counter does not do anything.
Entire contents of BlazorApp1.csproj:
<Project Sdk="Microsoft.NET.Sdk.Web">
<PropertyGroup>
<TargetFramework>netcoreapp3.1</TargetFramework>
</PropertyGroup>
</Project>
Note that the Get Started link I am following specifically says to use .NET Core 3.1 (vs 2.1). It says to OPTIONALLY update to the 3.2 preview, but that's only needed if I want to do a Blazor WebAssembly (which I don't). I prefer to only have released code on my system, so I don't want to updated to 3.2 Preview for something that is supposed to work with 3.1.
VS2019 defaulted to launching the app in Internet Explorer.
I changed it to launch it in Edge. It works in Edge.
Final update:
I got it to work in IE11. To do so:
I downloaded the Daddoon Blazor Polyfill package from here:
https://github.com/Daddoon/Blazor.Polyfill
From the downloaded zip, I copied Publish\Blazor.Polyfill.Publish\blazor.polyfill.min.js to a subfolder that I created, named "js", under the wwwroot subfolder in my project folder. I.e. in ToDoList\wwwroot, I created a subfolder named 'js' and then copied the blazor.polyfill.min.js file into that subfolder.
Then, I edited the file _Host.cshtml. I added the first line here (in front of the second line, which was already there, generated by VS and the Blazor Server template):
<script src="js/blazor.polyfill.min.js"></script>
<script src="_framework/blazor.server.js"></script>
I found a bunch of things that said "use Polyfills", but I couldn't find anything that said "here is how you actually do that." So, hopefully this helps someone else. Also, if I did something in a way that is suboptimal, hopefully someone will see this and tell me how to do it in a better way.
I had the same problem
To solve it, go to your project's Properties >> Debug >> uncheck Enable SSL. Then run your project by clicking e.g. IIS Express.
I'm using the Swashbuckle NuGet package to create Swagger documentation for my API. https://www.nuget.org/packages/Swashbuckle
I'm trying to make some minor changes to the UI - essentially just to add some corporate branding to the header.
I have added two files as embedded resources to my project, in a directory called resources.
These are injected into the UI via:
.EnableSwaggerUi(c =>
{
c.InjectStylesheet(thisAssembly, typeof(SwaggerConfig).Namespace + ".Resources.Swagger.css");
c.InjectJavaScript(thisAssembly, typeof(SwaggerConfig).Namespace + ".Resources.Swagger.js");
}
Which results in the following link being added to rendered page.
<link href="ext/ang_nav_api-Resources-Swagger-css" rel="stylesheet" type="text/css" media="screen">
This is all correct and the stylesheet works as expected.
However the .js script doesn't appear on the client.
Changing the c.InjectJavaScript to c.InjectStylesheet does inject the file as a <link> .. so I'm happy that the file itself is correctly embedded etc.
What could be wrong here?
The .js script will not appear on the client. (not on the way you would expect)
Look closely to the code of index.html:
https://github.com/domaindrivendev/Swashbuckle/blob/8223bedae706fec612c98ebbcee6b2d7033ae349/Swashbuckle.Core/SwaggerUi/CustomAssets/index.html#L98
Your customScripts will be loaded dynamically on the onComplete event
$.getScript(script);
I'm hoping someone with some experience in Breeze/Durandal 2 on .NET 4.0 will be able to assist me with this error, as I'm pretty new to the mix.
I've been working on a Durandal 2/KO/Require SPA project that lately has been compiling fine and running on my IIS7. I need this app to be compatible with IE8, so I imported the shim and sham js libs as such:
<!-- ECMAScript 5 compatibility shims for IE8 -->
<!--[if lt IE 9]>
<script src="lib/ie8/html5shiv.min.js"></script>
<script src="lib/ie8/respond.js"></script>
<script src="lib/ie8/es5-shim.min.js"></script>
<script src="lib/ie8/es5-sham.min.js"></script>
<![endif]-->
<script src="lib/jquery/jquery-1.9.1.min.js"></script>
<script src="lib/knockout/knockout-3.1.0.js"></script>
<script src="/Scripts/q.min.js"></script>
<script src="/Scripts/breeze.debug.js"></script>
<script src="lib/bootstrap/js/bootstrap.js"></script>
I also need to be able to access data from a DB so I tried adding BreezeJS to the mix. According to Breeze's documentation, in order for this to work I had to remake the project in VS as ASP.NET MVC4 Project using the Empty Template. After that I imported the Breeze files using NuGet:
Install-Package Breeze.WebApi
Then I added in my pre-existing views, controllers, libraries, css, etc. to the newly created project. Now when I compile using IE8 I get the following error. This error does not show up for Firefox or Chrome:
Unhandled exception at line 125, column 13 in

(Edited for readability)

I thought this might be a compatibility issue with JQuery so I attempted different versions there. I've made sure that my DocType is set to:
<!DOCTYPE html>
and that I have the following meta tag:
<meta http-equiv="X-UA-Compatible" content="IE=edge, chrome=1" />
However I doubt either of those would cause issues with IE8 and Durandal. Has anyone else experienced a similar issue to mine? Am I experiencing this error because I haven't configured something on the MVC4 side?
Any advice would be greatly appreciated.
Thank you
After further digging into the Durandal composition.js I found that the skipActivation parameter in the "tryActivate" function was undefined, which resulted in the error. I'm pretty sure this problem is a result of IE8 support from Durandal, so I went ahead and scrapped IE8 and I am now developing for IE9 and up.
This isn't a fix, but I've had enough headaches with this and I will be moving on ...
I think i have already read all the related questions here, but sadly i couldn't find an answer yet.
My problem is, locally everything runs fine without errors but when i deploy my website to my server, i'm getting there the following error:
The following sections have been defined but have not been rendered for the layout page >"~/Views/Shared/_Layout.cshtml": "styles"
I'm using Asp.Net MVC 4 with the Razor engine and .Net 4.5.
In _Layout.cshtml i have the following block defined:
<head>
....
#Styles.Render("~/Content/Css")
#Scripts.Render("~/bundles/modernizr")
#RenderSection("styles", required: false)
</head>
And in Index.cshtml the following block:
#section styles{
<link rel="stylesheet" href=... />
#Scripts.Render("~/bundles/js/somejs")
}
This is driving me crazy. If this error would also occur on my development machine, i could debug it. But it only happens on my server, locally everything runs fine.
Even other projects with similar code pieces run fine on my server.
Maybe someone has any hints for me?
I suspect that the contents of the _Layout.cshtml or Index.cshtml on your server is not what you think it is. Maybe the deployed version is different than what you have locally. Deployment went wrong?
I am a new bee to sencha 2.I wanted to run a basic application using sencha touch but unable to load the application.
Here is what I have done.
I have downloaded the notesApp from miamicoder and i am trying to run the first chapter.
I have attached the folder structure in the screenshot. Please have a look to understand the folder structure.
Here is my index.html
<!DOCTYPE html>
<html>
<head>
<title>My Notes</title>
<link href="sencha-touch.css" rel="stylesheet" type="text/css" />
<script src="sencha-touch-debug.js" type="text/javascript"></script>
<script src="app.js" type="text/javascript"></script>

I have downloaded sencha sdk 2.1 and took sencha-touch-debug.js and sencha-touch.css and placed in the root of the folder and referred from index.html as mentioned below. I used to to the same thing in sencha 1 and I was getting success but I am getting below error if I am trying to do the same with sencha 2.
I am getting errors as below.

Is it necessary to use senchatools and generate folder structure? Simply copying the two lib files (sencha-touch-debug.js and sencha-touch.css) and refer them from index.html will not work with sencha 2?
Please help.
Thank you.
I got the answer. Working with Sencha touch 2 needs to include the complete SDK in the project folder not only 2 library files like sencha 1. Including the complete framework will solve the issue.
Thanks
