# Razor form does not work in release version

edited March 2017

I developed Xamarin application for Android forum using Visual Studio 2017. The goal of application is to present math definitions and for this purpose I use vebwiew control and RazorView class. I use mathJax script to represent math expression in application. But I put attention that application works properly in debug mode and does not work in release mode.

Could you give us more information not is not working? A sample project would be really useful to debug the issue.
Also, this is more of an issue with Android/Forms not Visual Studio, you may want to post it in relevant forums

I tried to upload zip file with project, but zip file is too large. But I can show hear code itself. I created webView (xamarin) project. Class MainActivity.cs has following code
using System;
using Android.App;
using Android.Content;
using Android.Runtime;
using Android.Views;
using Android.Webkit;
using Android.Widget;
using Android.OS;
using WebApp1.Views;
using WebApp1.Models;

namespace WebApp1
{
[Activity(Label = "WebApp1", MainLauncher = true)]
public class MainActivity : Activity
{
protected override void OnCreate(Bundle bundle)
{
base.OnCreate(bundle);

        // Set our view from the "main" layout resource
SetContentView(Resource.Layout.Main);

var webView = FindViewById<WebView>(Resource.Id.webView);
webView.Settings.JavaScriptEnabled = true;

// Use subclassed WebViewClient to intercept hybrid native calls
webView.SetWebViewClient(new HybridWebViewClient());

// Render the view from the type generated from RazorView.cshtml
var model = new Model1() { Text = "Text \$$a_1^2\$$ goes here" };
var template = new RazorView() { Model = model };
var page = template.GenerateString();

// Load the rendered HTML into the view with a base URL
// that points to the root of the bundled Assets folder

}

private class HybridWebViewClient : WebViewClient
{
}
}


}
Class HybridWebViewClient had procedure which was called from content file when user clicked there button. I removed this code. But maybe I need similar code which application calls when screen is ready. But I am not sure what event it will be. The code for main.axml is simple
<?xml version="1.0" encoding="utf-8"?>

And file RazorView.cshtml has following code
@model WebApp1.Models.Model1

<script type="text/x-mathjax-config">
// This line adds numbers to all equations automatically, unless explicitly suppressed.
MathJax.Hub.Config({ TeX: { equationNumbers: {autoNumber: "all"} } });
//errorSettings: { message: ["[Math Processing Error]"] };
</script>


        <div data-role="content">
<p>
Module $$A$$
is called algebra
if we consider bilinear map
$g:A\times A\rightarrow A \label{product}$
Bilinear map
\eqref{product}
is called product and we use notation
$ab=g(a,b)\nonumber$
We call algebra $$A$$ commutative when
$ab=ba\nonumber$
for any $$a$$, $$b\in A$$.
</p>
<p>
We can identify linear map
$f:A\rightarrow A\nonumber$
of algebra $$A$$ and tensor $$p\in A\otimes A$$
using equality
$f(x)=p\circ x\nonumber$
if we assume
$(a\otimes b)\circ x=axb\label{a ox b o x}$
If algebra $$A$$ is commutative, then
we can identify tensor
$$a\otimes b$$ and product $$ab$$
and the equality
\eqref{a ox b o x}
gets familiar form
$(a\otimes b)\circ x=abx \nonumber$

</form>

Other files are created by project. If you think that better other forum, I will appreciate your advice. Code works in debug and does not work in release
