Unable install own google chrome extension - asp.net

Question

i want to host my own extension on my asp.net server (it's free web server, so i don't have access to machine.config etc.).
But the point of my problem is here. I put the packaged extension to server and i want use something like this:
protected void Page_Load(object sender, EventArgs e)
{
string file = Request.QueryString["f"];
if (file != null)
{
Response.Write("");
if (file == "0")
{
Response.ContentType = "application/x-chrome-extension";
Response.AddHeader("Content-Disposition", "attachment;filename=RemotePlay_extension.crx");
Response.TransmitFile("~/Extensions/Update/RemotePlay_extension.crx");
}
else
{
Response.ContentType = "application/x-chrome-extension";
Response.AddHeader("Content-Disposition", "attachment;filename=RemotePlay_extension.crx");
Response.TransmitFile("~/Extensions/RemotePlay_extension.crx");
}
}
}
But every time I get this error:
Source of extension manifest:
{
"name": "Remote Play",
"description": "DJ interface to use RP.",
"version": "0.0.0.2",
"update_url": "../Extensions/RemoteChrome_Update.xml",
"permissions": ["tabs", "http://*/*"],
"background": { "scripts": ["background.js"] },
"content_scripts": [{"matches": ["http://*/*"],"js": ["inject.js"]}],
"page_action": {"default_icon": "playico.png", "default_popup": "popup.html"},
"manifest_version": 2
}
What i'm doing wrong? Where is that error?

Answer 1

You can not trigger installation through Page_Load function and headers
You should have a link tag <link rel="chrome-webstore-item"
href="https://chrome.google.com/webstore/detail/apdfllckaahabafndbhieahigkjlhalf">
You can trigger installation through chrome.webstore.install(url, successCallback, failureCallback)
For more information check documentation.
