@ for event handler doesn't work in cshtml razor page

Steps to reproduce

Since I'm using the latest version of Vue.JS that supports short hand code for events, I'm trying to use @click instead of v-on:click inside the razor .cshtml file but it doesn't work. I'm developing an app and the backend is ASP.Net Core.

What is expected?

The expected result should be a working:
@click

What is actually happening?

After encoding the @click="submitTest",

Visual Studio says, "The name 'click' does not exist in the current context. Cannot resolve symbol 'click'"

In Razor syntax, @ character has its own meaning, so this should not actually a vue related "bug".
I guess you may need to use v-on:click directly to get through it because there is not option in vue's compiler to configure which character v-on shortland uses.

yes, I'm using the v-on for alternative. But I hope there's a plugin or something that supports @ of Vue.js in razor page.

[sirlancelot]

In Razor (cshtml) files, you must escape the @ with another @ like so:

<button @@click="submitTest">Submit</button>

A plugin would have to be done when the Razor files get compiled which is long before Vue gets a hold of it.

Closing as this doesn't have to be solved on vue side

@sirlancelot Thanks for that tip. Surely I'll use that alternative.
@posva I'll try to drop a feature enhancement in asp.net core section. :)

@sirlancelot How and where do you define submitTest()? I have to handle an event from vue component in cshtml (asp.net core) and getting error below. I defined the handler as a javascript method within <script> tag before the vue app is initialized. :

[Vue warn]: Property or method "mymethod" is not defined on the instance but referenced during render. Make sure that this property is reactive, either in the data option, or for class-based components, by initializing the property. See: https://vuejs.org/v2/guide/reactivity.html#Declaring-Reactive-Properties.
