I am running Windows 10, Visual Studio 2015, and Xamarin. I am rather new to Xamarin (just to set the ground level). I am currently having an issue after I updated recently. My application was working before the update. All my files were read-only, and I had no issues prior the update. Along with that, I have rebuilt the project and I the "clean and rebuild" for the project as well. I have tried it with multiple apps I have, and the other applications do not have this issue. The issue I am getting the following error below.

You should enable READ_EXTERNAL_STORAGE and WRITE_EXTERNAL_STORAGE permissions in Android.
You can follow this blog to enable the permission in runtime

I'm working with MRTK in Unity and I'm trying to access the namespace Microsoft.MixedReality in a script, but I get the error that MixedRealty doesn't exist at Microsoft namespace. However, at the MixedReality script all the namespaces are found, which troubles me for not knowing how to access the namespace.
At the same time, I'm getting this error at the console log:

I don't know what do I have to do to fix that error, I've tried reimporting all assets, regenerating project files, moving the script on which I need to access the namespace to another and erasing the Library folder, but hasn't worked. I hope someone knows a solution!
Thanks in advance.

I've tried looking around on google for some help, but have come up empty so far... Anybody have any ideas? I'm trying to connect to sql server and using DbContextOptionsBuilder().UseSqlServer() for the underlying connection.
I'm currently getting my old windows laptop up and running to see if it is because I'm on a Mac or not, but I thought I would get this question out there in the mean time.
Alright! So I'm not 100% sure why my connection string is failing when passing it directly to the DbContextOptionsBuilder().UseSqlServer(connectionString), but if I create a SqlConnection object before that, and pass that as the parameter to UseSqlServer, it works.
So got a workaround, but not sure why the error happens when just passing the connection string.
I've followed a number of tutorials for adding google OAUTH2 authentication to an existing MVC project, but I end up with the same issue involving a 404 to the client and the following trace generated:

I am using mono on linux, and I'm guessing it has something to do with the system web.config or routing. I've seen similar questions/answers but nothing I've read relates to this exact error. Is there a module I need to unregister or some other option that could be causing this?
I'm getting the following error when trying to set an icon on a Google Maps Map Marker:

I can see that it's failing in the UpdateMarker method which looks like the following:
public void UpdateMarker(IMarker markerInfo)
{
// _markerLookup is a dictionary defined earlier as:
// private Dictionary<IMarker,Android.Gms.Maps.Model.Marker> _markerLookup = new Dictionary<IMarker, Android.Gms.Maps.Model.Marker>();
// It is populated elsewhere
// Check if the dictionary contains a key for the given value
if (_markerLookup.ContainsKey(markerInfo))
{
Android.Gms.Maps.Model.Marker marker = _markerLookup[markerInfo];
marker.Position = new LatLng(markerInfo.MapCoordinate.Lat, markerInfo.MapCoordinate.Lng);
marker.Draggable = markerInfo.MarkerOptions.IsDraggable;
// Create BitmapDescriptor from Resource - Blue_Vehicle definitely exists and is a .png image
BitmapDescriptor bitmapDesc =
BitmapDescriptorFactory.FromResource(Resource.Drawable.Blue_Vehicle);
if (bitmapDesc != null)
{
marker.SetIcon(bitmapDesc);
}
}
}
The marker.SetIcon method is looking for a BitMapDescriptor which as described above is created from an image resource.
I don't understand why it's throwing an exception.
I would greatly appreciate if someone could shed some light on the issue.
I am trying to create a mobile application using MvvmCross v.4.4.0.
Application works correct. But if collapse application and lock the phone, and then unlock and press "Overview" android button application crash (only on the Xiaomi phone).
I think android kills activity and then unsuccessfully trying to recreate it.
Could you, please explain me, what I do wrong? How to fix it?

This is a linking issue. You have some kind of DialogProvider, which uses the Android.Text.Html.FromHtml method, which seems to be stripped out.
You can add expressions to LinkerPleaseInclude.cs to prevent the linker from removing code or you can add [Preserve(AllMembers = true)] attribute on your DialogProvider class.
