Why does the environment tag helper work on my machine but not on Azure?

This is a section on our _Layout.cshtml that I'm about to throw out the window.

<!-- CSS Scripts -->
    <environment include="Development">
        <script src="/ts/CS.js" asp-append-version="true" abp-ignore-src-modification="true"></script>
        <script src="/ts/CS.Url.js" asp-append-version="true" abp-ignore-src-modification="true"></script>
        <script src="/ts/CS.Settings.js" asp-append-version="true" abp-ignore-src-modification="true"></script>
        <script src="/ts/CS.Alert.js" asp-append-version="true" abp-ignore-src-modification="true"></script>
        <script src="/ts/CS.Modal.js" asp-append-version="true" abp-ignore-src-modification="true"></script>
    </environment>
    <environment include="Staging,Production">
        <script abp-src="/ts/CS.js" asp-append-version="true"></script>
        <script abp-src="/ts/CS.Url.js" asp-append-version="true"></script>
        <script abp-src="/ts/CS.Settings.js" asp-append-version="true"></script>
        <script abp-src="/ts/CS.Alert.js" asp-append-version="true"></script>
        <script abp-src="/ts/CS.Modal.js" asp-append-version="true"></script>
    </environment>

We use the environment tag helper in some spots to either use .min.js or .js, useful for debugging. I can see that if I personally set the ASPNETCORE_ENVIRONMENT variable from "Development" to "Production" that the tag helper continues to render the right content.

However, when I then push this through to be hosted on Azure - the content is missing completely.

Things I've tried:

What is going on here?! Is this not what other people do?

I was having the same issue with asp.net 3.0. It was rendering environment on local properly but when I deployed to Azure it stopped detecting it and rendering both the environment as it is.

Here is the solution. Just add the below line in your _Layout.cshtml file in the beginning.

@addTagHelper *, Microsoft.AspNetCore.Mvc.TagHelpers

enter image description here it will fix the issue.

thanks

The exclude="Development" works if you want to apply the same settings to all other environment except Development. But I came across a time when I need to have different settings for staging and production. So I had to be specific.

The solution I use in order for the environment tag helper to work on Azure is that you need to create an entry for the ASPNETCORE_ENVIRONMENT under Settings -> Configuration -> Application settings on Azure:

enter image description here

If you don't have that defined on Azure, when you publish, it will default to Production if I remember correctly, which is weird.

Staging, production is not understandable to the server. You need to change this as follow.

If You are working in local than our script will work which is inside

<environment include="Development">
</environment>

if You are working on server like azure and others than our script will work which is inside

<environment exclude="Development">
</environment>

You need to change your following code 

<environment include="Staging,Production">
        <script abp-src="/ts/CS.js" asp-append-version="true"></script>
        <script abp-src="/ts/CS.Url.js" asp-append-version="true"></script>
        <script abp-src="/ts/CS.Settings.js" asp-append-version="true"></script>
        <script abp-src="/ts/CS.Alert.js" asp-append-version="true"></script>
        <script abp-src="/ts/CS.Modal.js" asp-append-version="true"></script>    </environment>

as

<environment exclude="Development">
                <script abp-src="/ts/CS.js" asp-append-version="true"></script>
                <script abp-src="/ts/CS.Url.js" asp-append-version="true"></script>
                <script abp-src="/ts/CS.Settings.js" asp-append-version="true"></script>
                <script abp-src="/ts/CS.Alert.js" asp-append-version="true"></script>
                <script abp-src="/ts/CS.Modal.js" asp-append-version="true"></script> 
   </environment>

It will work at any server.
