Description Marcel Bradea 2014-02-26 15:53:25 UTC
Certain components do not load up in the Component Store in Visual Studio.

After clicking on a component (see screenshot 1), the component details screen briefly flashes for a fraction of a second then the "Unable to connect to the component store." error shows up (screenshot 2). Clicking through the error bar up top and clicking 'Allow blocked content.....' only makes the error bar go away, but the components subsequently still don't load.

This seems to only be happening for certain components and not others.
For example:
- happens for Google Play Services, Azure Mobile Services, ActionAlert
- doesn't happen for RestSharp, JSON.Net, ModernHttpClient

What is special about these components and is there certain configuration that needs to be set up for them?

NOTE: All external web requests go through a proxy here internally, if that's of any relevance.

I have checked this issue and able to added "Google Play Services, Azure Mobile Services" Refer screen cast: http://screencast.com/t/NyjCYrjm

Please recheck at this issue and let us know if still facing same issue.
Checked With:

VS 2012
X iOS: 1.10.39
Comment 4 Marcel Bradea 2014-02-27 09:56:58 UTC
Yes it is still having the same issue. This is preventing us from moving forward on our project (cannot get required Google Play Services library).

The environment used:
- Windows 7
- Visual Studio 2013
- Xamarin.Android 4.10.02014
- Xamarin.iOS 1.10.39

Hi Marcel,

We will still need to investigate this further, but for now I want to make sure you can work around this issue and use the components.

you should be able to work around this by downloading the components directly from the component store (using a browser), and adding the included assemblies as a reference.

Here's the url for the store:

Is there a log somewhere that we can send you to investigate what thee cause of this is?
Comment 7 Shruti 2015-07-15 06:57:22 UTC

@Marcel, are you behind an authenticating proxy server. I am about to log a bug stating that the Component can not be downloaded by VS2015 when I am connected through an authenticating proxy.

Internet Options that resolved the issue

I got the same problem and resolved by going to Internet Explorer -> Internet Options -> Advanced and under the security settings checked: Use TLS 1.0, Use TLS 1.1 and Use TLS 1.2.

I am facing the same problem. I am using a special company proxy for my development tools (like VS). So i use a "<proxy 
 proxyaddress="http://compproxy:3128" bypassonlocal="true" />proxy" directive in devcon.exe.config.

When trying to install some components (like azure messaging) via AddComponent in Visual Studio the process silently fails (i can search for a component, but hitting the add button just closes the window and does nothing).

When i open a project which already includes a component reference to one of these components (f.e. the Xamarin Evolve project) i get an error on the component, saying that adding the component failed because "ServicePointManager does not support the https scheme".

If the Xamarin plugin can not correctly handle the proxy settings(http/https) for Visual Studio (in devcon.exe.config) it would probably be the best, if the proxy settings can be configured independently (like this has to be done for nuget).
Comment 11 b.stoltefuss 2017-08-31 16:46:48 UTC
@Jose's workaround does not work for me, as i am using a different proxy for my development tools (like VS, Eclipse etc.).
