The browser or gateway element with ID 'Safari1Plus' cannot be found

Question

I have a stranger error on my machine, I have a .browser file in app_browser of my application and it has the following lines:

browsers>
<!-- Disable the Menu Adapter for the Safari/Chrome browser-->
<browser refID="Safari1Plus">
    <controlAdapters>
        <adapter controlType="System.Web.UI.WebControls.Menu"
                         adapterType="" />
    </controlAdapters>
</browser>

When I try to load the application I get the error in the subject but none of my colleagues (We are all using the same code base) gets it.

I have an instinct that the error is linked to IIS and I spent a whole day trying to get my head around it to no success.

To make this work in the meantime, I have replaced the safari1plus with default, but the underlaying problem is that I have a gridview on one of my pages that doesn't display anything on my local machine and it does work on other devs machine. I am not sure as to why or the cause of this but it looks like it is a configuration based issue and maybe one or two people have had to deal with this.

Anyone with an idea is welcome.

Obviously the OS is Win 7 64 bits, with VS2010 Professional and IIS7.

also I have checked the content of Windows\Microsoft.NET\Framework\v2.0.50727\CONFIG\Browsers and Windows\Microsoft.NET\Framework\v4.0.30319\Config\Browsers and also on the Framework64 Dir and all looks the same(compared to other devs machine)

Many thanks

Answer 1

You should look up the exact refId in the corresponding browser definitions files located at <windir>\Microsoft.NET\Framework[64]\<ver>\CONFIG\Browsers.

For .NET 4.0, the refId is WebKit and not Safari1Plus.

As I suspected this was an IIS issue and I accidentally resolved it by checking all the settings of all the web apps. My application has 7 apps that shares the same Data layer.

The way I resolved it to make sure that all apps use ASP.Net v2.0 integrated pool as application pool, obviously this doesn't make any sense, but that is what worked for me.
