I have visual studio 2017 v2 and am trying to install the Azure functions extension. I have tried on a fresh vs install on a fresh PC as well as an older one. Each time I get the error message 'The extension cannot be installed to this product due to prerequisites that cannot be resolved'. It doesn't tell me what they are or what I can do to resolve the problem. How can I fix the problem?
Last I checked (a couple of weeks ago) the Azure functions extensions/tooling is only available with VS2017 preview.
You can install it alongside your other stable VS2017 install - see the azure functions blog.

I have this problem with the setup of Android SDK in Virtual Studio Community 2015. Whenever I try to install or repair VS, I always get problems with the setup of API Level 19 and 21,21 and 23. It always says that the packages were not downloaded and I should check my internet connection. However, my internet connection is working perfectly. I have seen many other users having similar problems, but none of the proposed fixes work for me. I have reinstalled VS twice and repaired it like 3 or 4 times. I checked my Java version and my proxy settings or tried installing them via the Android SDK Manager/alongside Android Studio. So far without any luck. I hope I have not overseen any fixes.
Unfortunately, the log is very long, so I can´t post it here (if you have any suggestions where I can post it, please tell me!). In the links you will find two screenshots of the error message I get.
Can you help me?
All I did was install Java SE Development Kit 8u151 from Oracle (Apparently VS 2015 uses Java 7 instead of 8) and then run VS 2015 as administrator and modify. The third party SDK's (19, 21, 23 & 22) were available and all installed correctly. Wish I had of known this before multiple installs and eventually a reinstall of my OS ...suppose I could have done with a clean slate though.
I was able to solved the problem above using the suggestion and comment of #Richard_Norton and #bugzapper from, https://social.msdn.microsoft.com/Forums/sqlserver/en-US/780c0b11-41da-4935-9ae5-dadf38292b51/android-sdk-setup-api-not-installed?forum=vssetup .
I uninstall the older version of Java SE Development Kit which is not Version 8.
I download and install the Java SE Development Kit Version 8 which you can get in here http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html .
Then after that i modify Visual Studio 2015 to Install Android SDK Setup (API Level 19 and 21), and 23.
I Hope, this answer can help future someone who is encountering this kind of problem.
Refer to the error message, you can have a try with the following methods:
Open Android SDK Manager and click Tools-Options… and check the option “Force https://... Sources to be fetched using https://...” and try to download those android SDK packages again. If you already tried this before, you can ignore it.
Check this blog: Visual Studio 2015 install failures (Android SDK Setup) behind a Proxy and follow the steps as below to fix it:
• BEFORE installing Visual Studio, create a file at this location: %USERPROFILE%.android\androidtool.cfg
• In the androidtool.cfg file that you just created, place those contents that you can find from the blog. Make sure to update “http.proxyPort” and “http.proxyHost” in the file!
• Install Visual Studio normally
Have a look at this similar issue: Visual Studio 2015 setup issue with Android SDK – hack it!, if you found the same root cause: all google repositories don’t have this package anymore on your side, you can try to create your own repository contains this missing package and let Visual Studio setup “think” he download the package and unzip it successfully.
BTW, the installation log file can upload to https://onedrive.live.com/ and share the link here.
Just start the SDK Manager from Visual Studio's menu (Tools/Android/Android SDK Manager...) and select the desired API level you do want and download them!
Anyhow, check with the SDK Manager, this is THE tool to get the Android SDK and at times you will need to update stuff through it!
I'm opening a solution which has a dependency on an outdated version of the Azure SDK such that Web PI wont install it.
This leaves me with the following error when I build the project:
WAT080 : Failed to locate the Microsoft Azure SDK. Please make sure the Microsoft Azure SDK v2.7 is installed.
What's the least amount of
steps I need to execute and
junk I can put into my environment
to make it load in VS and compile?
Navigate to the archived downloads page: https://azure.microsoft.com/en-gb/downloads/archive-net-downloads/
Follow the trail via the appropriate Azure SDK for .NET (As of Mar 2017, v2.7.1 is here)
Click the download button
Select MicrosoftAzureAuthoringTools-x64.msi
Select MicrosoftAzureLibsForNet-x64.msi <- x86 is not useful
Select MicrosoftAzureTools.VS140.exe <- 14:- VS 2015
I downloaded and installed each separately
HACK: My installation of VS2015 was slightly mangled, so I was still seeing a message from VS offering to install the 2.7 tools. I was able to get over that by installing the latest (2.9 at time of writing) tools, whereupon I got a clean build. I'll be doing a clean reinstall of VS and will research whether that can be avoided
I recently installed VS 2015 Enterprise. Im trying to add Xamarin for VS from the setup menu, and when downloading it just hangs at this point for hours and eventually says an error was encountered. This is my 5th installation attempt. I dont have any other VS version installed on my machine.
Try this:
Download Bonjour Print Services for Windows v2.0.2 and install from the following link: https://support.apple.com/kb/DL999?locale=en_US
Then activate bonjour service in win10. Refer to:https://discussions.apple.com/thread/7420758?start=0&tstart=0
Then you can re-install VS to see if it works.
By the way, that's an open bug.
Have you tried to install it by downloading the kit from xamarin.com? What do you mean by "from the setup menu"?
I am moving towards Xamarin for cross-platform application development. I already had VS2015 installed, I downloaded Xamarin tools(vstoolsforxamarin.exe) from their website and when I install them after a long wait VS says "setup completed with errors"and it does not download and install Android SDK for API 19,20,23, It always say:"Please check your internet connection and try again" and i am sure that my internet connection doesn't get disturbed during all this process. I have tried this 3 times now, tried by uninstalling VS2015, installing it again but got the same error. What is the problem that is causing this? I already have Android Studio installed, with its SDK manager. Any help would be appreciated, that to get Xamarin running in VS2015.
EDIT:
Solution:
I already had Android Studio and its SDK on my system, going to Tools>Options>Xamarin from Visual Studio and giving path of the Android SDK solved my problem. Read this answer on StackOverflow somewhere!
Seems like this issue is caused because Visual Studio is trying to download thrid-party libraries (Android SDK). You can fix this from Control-Panel
Have a look at this post.
Make sure you have installed Java JDK, I had similar issue reported here
Visual Studio 2015 Enterprise Reports Internet Connectivity Issue while there is no issues with networking
As mwilson64 answered in response to Android SDK Setup API not installed (same as linked above on "Have a look at this post."), my steps to resolve:
Create file %USERPROFILE%.android\androidtool.cfg
Paste the following into new file (created in step 1):
# Settings for Android Tool
# Last updated: Wed May 19 17:09:27 UTC 2017
http.proxyPort=8888
sdkman.enable.previews=false
http.proxyHost=127.0.0.1
sdkman.ask.adb.restart=false
sdkman.show.update.only=true
sdkman.force.http=false
sdkman.use.dl.cache=true
Replace values in proxyPort and proxyHost with your company's proxy settings.
I've just installed the April 2015 release of the Azure SDK. It is version 2.6 and previously I was on 2.5. Now one of my projects will not load. It is the shared project in a Windows Universal application.
When I right-click the project and choose 'reload' I get the pop-up error
The method or operation is not implemented
The output window gives more detail:
Things.Shared.shproj : error : The composition produced a single
composition error. The root cause is provided below. Review the
CompositionException.Errors property for more detailed information.

The other parts to the Windows Universal app (the Windows 8.1 project and the Windows Phone 8.1 project) have two Azure NuGet packages installed: Windows Azure Mobile Services 1.3.2 and Windows Azure Storage 4.3.0. (N.B. Those two projects load without issue.)
This is not a show stopper for me since uninstalling the Azure SDK 2.6 removes the load failure. To uninstall I go via the Control Panel to 'uninstall or change a program' and then uninstall Microsoft Azure Tools for Microsoft Visual Studio 2013 - v2.6
I would like to know how to fix this without uninstalling the Azure SDK 4.6.
Over on the Azure Mobile Services forum Chuck Weininger has posted the following answer:
The [fixed] build of Azure SDK 2.6 is now available, but it may not have
propagated to all download servers yet.
You can run the Web Platform Installer and if you don’t have the new
build installed, it should allow you to install 2.6 again. But it
might not if you are accessing a download server that doesn’t have the
new bits yet. If WebPI doesn't allow you to install 2.6 again, then
wait a few hours and try again.
The build number for the version with the fixes is build
2.6.30508.1601. You can identify the build of the SDK from Control Panel -> Programs and Features -> Microsoft Azure Tools for Microsoft
Visual Studio 2013 – v 2.6. The Version column will display the build
number
I have followed Chuck's instructions and have the new build and the shared project now loads without issue.
We have been able to reproduce the issue, but don't have a workaround at this time. If you want to use the Universal App projects with VS 2013, you will have to uninstall Azure SDK for VS 2.6. The issue does not happen on VS 2015 RC if you would like to give that a try. We hope to have news soon about how we can get a fix for this issue on VS 2013.
