I just downloaded Xamarin for visual studio 2015. I did everything written in xamarin website. But when i try to build an android app, it shows an "Unsupported class version \ Unsupported Major.Minor Version" error. How can i fix it?
Screenshot of error report
This error is related with the manifest.
Can you show us the manifest for your app ?

I have several solutions where I would say about 20% of the time I get a resource not found exception like the following during run-time.
android.content.res.Resources$NotFoundException: Unable to find resource ID #0x7f080007
Usually, I can temporarily fix the issue by cleaning the solution and restarting visual studio and then rebuilding. The resource isn't always the same between builds. Sometimes it is a textview other times it is a drawable etc.
Note, the projects always builds fine, the error is always an exception thrown at runtime.
Has anyone else experienced something like this? Any advise on how I can debug the issue? I've done things like make sure resources don't contain forbidden characters etc.

I just created a new Xamarin App: Xaml Portable App in Visual Studio 2015 Enterprise. Whenever I try to deploy the UWP Project I get the following error:
DEP0001: Unexpected Error: -2147467259 Project.UWP
I updated Visual Studio and all Nuget Packages, but I'm still getting the same error. I google the error code, but could not find anything useful.
What am I doing wrong? The Project is still empty/default.
Had the same problem with a bit older SDK and Emulator. Installed the newest ones from Microsoft SDK Archive - Version 10.0.14393.0 - and it works now.
I'm using Xamarin Studio v5.10.3 and Xcode v7.3.1
I get this error on Xamarin Studio
A valid Xcode installation could not be found. If your copy of Xcode is installed to a non-standard prefix, please specify the location in Xamarin Studio Community's Preferences under 'SDK location'.
How can I fix this?
All is explained in the error :
1) You have to have a valid installed copy of Xcode
OR
2) You have to updated you Xamarin Studio configuration to specify the path to you Xcode unofficial installation.
When I start visual studio, the "Resharper exception browser" comes up with an error message suggesting that I have an unsupported framework version.
Questions:
What is having that unsupported framework version? Visual studio?
Can I get rid of that error message without disabling resharper?
Why did this error suddenly happen?
This is due to an older version of ReSharper that was released before .net framework 4.6. Unfortunately, the only fix is to update to a more recent version - 9.0 fixes this, although we're currently on 10.1 (aka 2016.1)
I'm trying to create an Editor Classifier Template project and run it. When I attempt to build I get an error message stating:
"Error trying to read the VSIX manifest file 'extension.vsixmanifest'. Exception has been thrown by target of invocation."
Any thoughts? I've tried googling this but didn't have any luck.
I am working with Visual Studio 2010 Ultimate and the VS 2010 SDK Beta 1.
Thanks,
Nick
Are you using a matching version of the SDK and the product? The Beta 1 SDK won't work against anything other than Beta 1 of VS2010.
