Xamarin iOS Release Build fails - visual-studio

I am using Xamarin iOS in Visual Studio 2017 for Windows!
Building and debugging the debug Version of my App via a build host works great. But when I try to build the Release Version it says:
1>C:\Program Files (x86)\Microsoft Visual Studio\2017\Enterprise\MSBuild\15.0\Bin\Microsoft.Common.CurrentVersion.targets(3463,5): error MSB6006: "sgen.exe" exited with code 1.
Signing Identities are installed and vislible in VS.
I also found this Blog post. But the workaround is only for Mac Users.
Does anyone know what's wrong here?
Thanks!

Have you configured your iOS release? if not this may be the solution.
In Visual Studio, open Solution Explorer (Keyboard: Ctrl + Alt + L).
Right-click your solution and then click Configuration Manager.
On the configuration manager dialog box open the active solution configuration drop-down menu and click New.
On the new solution configuration dialog box:
For Name, enter iOS Release
Open Copy settings from drop-down menu and select Release.
Clear the Create new project configurations dialog box.
Open the Active solution platform drop-down menu:
Select iPhoneSimulator and clear the check boxes on all rows except
your Xamarin.iOS project and any projects (for example, portable class libraries) it depends on.
Repeat this step for iPhone.

I get "the application has not been built" from Visual Studio 2019 on Mac for Xamarin.IOS app project. Target is iphone, not sim

Project was copied over from a VS on Windows, on which it builds and runs okay through same Mac, onto an iPhone.
I just installed VS on the Mac.
Anything special on it I need to do?
Check for the default project selected to build & deploy.
Often when switching projects from Windows to Mac the default deploy project is selected as Droid. The same is for vice versa when switching projects from Mac to Windows the default deploy project is selected as iPhone.
If the problem still persists try to -
Try deleting the packages folder containing nuggets.
Restore nugget packages.
Clean & Rebuild Solution.
Try the following:
Delete the Bin and Obj folder.
Clean the solution
Rebuild the solution
In the top left hand corner choose Ad-Hoc|iPhone if you have this option
If not select debug | iPhone
In the "Solution" pane, check if any of your projects have a blue info icon next to them that, when hovered over, display "Project not built in active configuration". If so, you might have to try the following to add them to the build:
In the Solution pane, Control+Click on the root project > Options.
In the Solution Options popup, expand "Build" on the left (if needed) and select "Configurations" below it.
On the right, switch to the "Configuration Mappings" tab.
Add a check to the box in the "Build" column for any Solution Item that needs to be part of your build. Set the drop down in the "Configuration" column to the appropriate value (guessing "Debug|iPhone" since it sounds like you were trying to test on an actual iPhone, not the simulator).
Click "OK" to close the Solution Options popup.
Build menu > Clean All. Build menu > Rebuild All.
Try running the project again, either with the "Play" arrow in the header or the Run menu > Start debugging.
The steps above were generated using Visual Studio for Mac Professional, v8.10.6 (build 10).
I had this same error, but it was a clean/new project.
In project's Options, under Build/Mac Signing, I checked 'Sign the application bundle; and selected the 'Mac Developer (Automatic)' identity.

Visual Studio 2017 code colors not working correctly [duplicate]

When I want to edit C# Unity scripts, they open in Visual Studio. It is supposed to provide auto complete for all Unity related code, but it doesn't work.
Here you can see the missing functionality:
As seen, the transform object does not open the autocomplete menu.
Unity version: 5.5.2f1
Visual studio 2015
Visual Studio Tools for Unity is installed
There is no auto-completion because the script says "Miscellaneous Files" instead of the of the name of the Project. Take a look at the image below that came from the video in your question:
The "Miscellaneous Files" message can happen for many reasons:
It can happen when you open your Unity C# file from another folder instead of opening it from Unity Editor.
This can also happen because Unity crashed while Visual Studio is still open therefore corrupting some files.
It can happen because Unity was closed then re-opened but is no longer connected to Visual Studio. When Visual Studio is opened you get "Miscellaneous Files" and no auto-completion.
This can happen when Visual Studio Tools for unity is not installed.
When you create a script from Unity then quickly open it before Unity finish processing it or before the round icon animation stuff finish animating.
Most of the times, restarting Unity and Visual Studio should fix this.
I can't tell which one is causing the problem but I will cover the most likely solution to fix this.
Fix Part 1:
Download and Install Visual Studio Tools for unity from this link. Do this while Unity and Visual Studio are both closed.
From Unity Editor, go to Edit → Preferences... → External Tools. On the External Script Editor drop down menu, change that to Visual Studio 2015.
Fix Part 2:
If newly created C# files are coming up as Miscellaneous then follow the instruction below:
From Visual Studio, go to Tools → Options... → Tools for Unity → Miscellaneous. Under Show connectivity icon, set it to true then restart Visual Studio.
When you re-start, connection icon should now be available in Visual Studio. Click it then choose the Unity instance to connect to. The red 'x' icon should now turn into a brown checkmark icon. Now, when you create a new C# file in Unity, it should open without saying Miscellaneous.
Fix Part 3:
Still not fixed?
Re-import project then open C# Project.
Close Visual Studio.
From Unity, re-import project by going to Assets → Reimport All.
Now, open the project in Visual Studio by going to Assets → Open C# Project. This will reload the project and fix possible solution file problems.
Fix Part 4:
Still not fixed?
Fix each C# file individually.
Click on Show All Files icon.
Select the script that doesn't do auto-complete then right-click and select Include In Project.
Fix Part 5:
Not fixed yet?
Credit goes to chrisvarnz for this particular solution which seems to have worked for multiple people.
Close Visual Studio
Go your project directory and delete all the generated Visual Studio files.
These are the files extensions to delete:
.csproj
.user
.sln
Example:
Let's say that the name of your Project is called Target_Shoot, these are what the files to delete should look like:
Target_Shoot.csproj
Target_Shoot.Editor.csproj
Target_Shoot.Editor.csproj.user
Target_Shoot.Player.csproj
Target_Shoot.Player.csproj.user
Target_Shoot.sln
Do not delete anything else.
Double click on the script again from Unity which should generate new Visual Studio file then open Visual Studio. This may solve your problem.
Fix Part 6:
If not working, check if you are having this error:
The "GetReferenceNearestTargetFrameworkTask" task was not found
Install Nuget PackageManager from here.
Restart Visual Studio.
See this answer for more information.
Fix Part 7
Make sure all of the projects are loaded.
In Solution Explorer it should tell you # of # projects.
If all of the projects are not showing, right click on "Solution (# of # projects)" and click Load Projects.
Try this,
In Unity Editor Go to Menu, Click on Edit -> Preferences -> External Tools -> External Script Editor. Set it to Visual Studio (your installed version of VS).
Now in Menubar go to Edit -> Project Settings -> Player Settings -> Other Settings -> Under Configuration -> Check API Compatibility Level -> Change it to your installed .Net version. In my case I set it to .Net 4.x
Now if Visual Studio is running already go to Visual Studio, it will ask to reload project. Reload the project. Check if it works, if not close Visual Studio. Now Open cs file from Unity Editor, and now it should work.
I found another way to fix this issue in a more convenient manner:
Select the broken file in Solution Explorer.
Open its Properties.
Switch field "Build Action" from "Compile" to "None".
Then switch it back to "Compile".
This will kill the synchronization between Unity and Visual Studio somehow.
The next time Visual Studio will reload the project, it will prompt a warning.
Just click on "Discard".
If you have done all of the above and still isn't working , just try this:
Note: you should have updated VS.
Goto Unity > edit> preference >External tools> external script editor.
Somehow for me I had not selected "visual studio" for external script editor and it was not working. As soon as i selected this and doubled clicked on c# file from unity it started working.
I hope it helps you too.
Unload and reload the project, in Visual Studio:
right click your project in Solution Explorer
select Unload Project
select Reload Project
Fixed!
I found this solution to work the best (easiest), having run into the problem multiple times.

Select the External Tools tab on the left.
For External Script Editor, Choose the Visual Studio version you have.
Click regenerate Files

I hit the same issues today using Visual Studio 2017 15.4.5 with Unity 2017.
I was able to fix the issue by right clicking on the project in Visual Studio and changing the target framework from 3.5 to 4.5.
Hope this helps anyone else in a similar scenario.
Two Alternative Options:
Fix 1
#singleton pointed me in this direction. Instead of changing the target in Visual Studio you should change it in Unity since the project is auto-generated.
First delete the auto generated Visual Studio files:
.csproj
.user
.sln
Then from within Unity go to PlayerSettings and under 'Other Settings' change the 'Scripting Runtime Version' from Stable 3.5 to Experimental 4.6.
However, that didn't fix it for me.
Fix 2
I noticed all of the references to Unity related code was marked with a yellow warning. Check your error logs and see if this is the case. In particular see if you get the following error: getreferenceNearestTargetframeworkTask
If so try:
Start Visual Studio Installer again.
On the Build Tools 2017, click Modify,
Ensure that "Nuget targets and build tasks" are ticked. This should become ticked if you click on Universal Windows Platform development.
Update 2020 with Visual Studio Community 2019 and Unity 2019.3:
Open Visual Studio Installer as Administrator, select to modify your current installation and add "Game development for Unity"
If you add a new c# script in Unity now, and open it (automatically) with Visual Studio, it is not described as "Miscellaneous" at the top of the window but with "Assembly-CSharp", and the autocomplete works.
i found my solution by creating the .cs file from visual studio itself instead of unity editor
right click on project folder in solution explorer
add > new item
type "unity" on the search field on the top right
select "CSharp MonoBehaviour"
name your script on the bottom and click Add
In my case, correct .net version was not installed on my PC. I install the .net 3.5 on my pc and that worked for me.
For Windows or macOS:
Download/Install the Visual Studio IDE (with Unity Tools)
When installing, make sure you include installation of
Game development with Unity
Then using Unity (you can double click one of your C# files), open a new C# project and the Visual Studio IDE should open with your new project structure.
From there, you should be able to see what you are looking for.
For example:
For Linux (suggestion):
Try Monodevelop - Additional Information, it provides code completion/hints.
My autocomplete also didn't work because Visual Studio Tools for Unity wasn't installed. So, after you install that, delete the auto generated Visual Studio files. Others said that you open file again and the problem is solved but it's not.
The trick is: instead of normally double-clicking the file, you need to open the C# file from Unity by right click and then "Open C# Project".
The issue I faced was that the C# Project was targeting a different .NET Framework (4.7.2), whereas the Unity project had a different target (.NET 3.5).
I fixed this by changing the target in Unity as-
File -> Build Settings -> Player Settings -> Other Settings -> API
Compatibility Level : Set it to the .NET version you already have
installed (Check your .NET Version here). In my case, it was 4.x
After this, Visual Studio worked perfectly and autocorrect was fixed too.
Try pressing Ctrl + Alt + Space (which toggles between suggestion and standard completion modes)
For some odd reason, the "Game development with Unity" tool can become disabled in Visual Studio.
To fix this..
Open Visual Studio
Go to Extensions → "Manage Extensions" → Installed
Find "Visual Studio 2019 Tools for Unity"
If it is disabled, enable it
Restart VS

The following works for me.
Go to Edit->Preferences->External Tools->External Script Editor Select Scripting Editor
I solved to install the same version of .NET on WIN that was configured in my Unity project. (Player Settings)
Go to Options on the Tools menu and then select Documents in the Environment node. (If Documents does not appear in the list, select Show all settings in the Options dialog box.)
Put a tick on "Miscellaneous files in Solution Explorer" and Click OK. (This option displays the "Miscellaneous Files" node in Solution Explorer. Miscellaneous files are files that are not associated with a project or solution but can appear in Solution Explorer for your convenience if you tick this option.)
Locate your file in the Solution Explorer under "Miscellaneous Files". Then drag and drop your file to where it should belong and voila! This will copy the file to where you drop it. You may now safely delete the older file under Miscellaneous Files folder if you wish to do so

In case Scripts folder is not visible:
Click on "Show all files" in Solution Explorer
Locate the Scripts folder.
Right Click on Scripts and select "Include in Project"
Keep in mind that if you are using the ReSharper tool, it will override the IntelliSense and show it's own. To change that, on VS, go to Extensions -> ReSharper -> Options -> IntelliSense -> General then choose Visual Studio and not ReSharper.
Before restarting and/or re-installing VS, First try opening any other of your projects to see if Intellisence works, if it does, then issue probably lies with your current project. First, most probable victim would be the NUGET packages with pending updates. To Fix this,
Right click on references
Proceed to Manage NUGET Packages Under NUGET Packages
proceed to updates Install Updates and recheck Intellisence
I tried all of these but ended up finding out that I needed to right-click the solution in Solution Explorer and add existing items and find the C# assembly file in Window's Explorer. There seem to be a bazillion different problems that give you this error, this is likely the most simple solution. If you double click on your script from unity, it does not seem to drag the assembly along.
Another possible fix:
In the project window, click on the Assets folder
Right click, and Create -> C# Script
Double click that, and wait.
For some reason, this work.
None of the above solutions worked for me. However I opened the ProjectName.CSPROJ file and manually added the new file and it worked like charm
What worked me is that I copied all the code inside the broken class and removed that file.
Then, I opened an empty file with the same name and pasted back.
Result: beautiful syntax highlights came back!
"Preferences" -> "External tools" -> set you exteranl tool
Thats one fix. Also for VS you can use ReSharper by JetBrains, but I recommend use Rider. That one is also free for students.
It provides less performance than visual studio, but more than VS+Resharper definitely.
Have a good day, mate)
Try with combination: Ctrl + Alt + Space
one of the above methods are worked for me and I just found a solution to this problem,
1. First, go to the project directory and delete .sln file
2. Second, go to unity and double click your script. Then Visual Studio will be open with an error,
Then click ok and close Visual Studio editor.
Finally, turn off your Windows Defender and then go to your project directory and there will be .csproj file. Just double click and open this from your Visual Studio editor and open the scripts folder inside the assets folder and open the scripts and autocompletion will be working perfectly fine.
These actions solved the problem for my projects in Visual Studio 2022

Why is the Windows 'For developers' Settings dialog window appearing each time I create a new Zebble for Xamarin - Cross Platform Solution project?

Using Visual Studio 2015 Update 3, I am trying to follow the video instructions for creating a new project found here: http://zebble.net/docs/creating-a-new-project
I do the following:
I ensure the Zebble extension is installed
I click the start screen's 'New Project' link
I select 'Zebble for Xamarin - Cross Platform Solution' as project type
I name the project 'My application'
I click the 'OK' button
What happens next is:
The Windows 'Settings' dialog window appears on top off my Visual Studio window and in the left hand pane 'For developers' is selected (the same dialog that would appear if you pressed the Windows key on your keyboard and then typed "settings" followed by pressing the Enter key)
To resolve the Windows 'For developers' Settings dialog window appearing each time, you need to enable your device for development.
To enable Developer mode:
From the For developers settings dialog, choose the 'Developer mode'
Read the disclaimer for the setting you chose, then click Yes to accept the change.
After clicking Yes, you may be prompted to restart your computer.
Source: Enable your device for development
Make sure you are using the latest version of the Zebble Visual
Studio extension.
Try running your visual studio in admin mode.
Also see I can not build the generated UWP project by Zebble

Unable to select android emulator in Xamarin VS

I'm using Visual Studio Enterprise 2015 Edition (Update 3), with Xamarin 4.2 installed.
I have the emulators downloaded via Xamarin Android Player, however I don't have an option to select the emulators from Visual Studio (Refer attached image).
VS Select Emulator
There is no emulator dropdown next to debug button in toolbar, and VS always defaults to the first emulator, and doesn't let me choose one, even if there are multiple emulators available in XAP.
Any help is greatly appreciated.
Thanks!
After trying to figure out the problem for days, I was finally able to identify the real cause of the issue. I had to enable Standard toolbar in VS (Right-click on Toolbar, and select Standard. Refer Screenshot) to finally have the ability to select emulators.
I was under the assumption that the emulator list appears in Debug toolbar, and did not try checking the toolbar menu earlier.
Thanks for all the replies, and hope this helps someone else facing this issue.
This would appear to be this bug:
https://bugzilla.xamarin.com/show_bug.cgi?id=44487
If so, the issue occurs when selecting the startup project with the drop down list in the tool bar. Instead try selecting the start up project by right-clicking on the project on the Solution Explorer and choose "Set as startup project"
It seems you didn't select the startup project. In Solution Explorer right click on your Android project and choose "Set as StartUp Project". Then default emulator options should be visible and you can change it via drop down menu.
Anyway I recomend you to use Visual Studio emulator

Do not see an option to debug a Windows Phone Application?

I installed Windows SDK before and there was an option showing up in Visual Studio to test an application by debugging. I had to reinstall the SDK again but the only Option I was seeing was Start instead of any other WVGA OR WXGA simulator. Is there anyway I can fix this? Hyper-V option is also enabled and I am using 2011 Macbook Air 13.3"
If the options you refer to are the ones in the Visual Studio menu with the green arrow, it only shows the options for the StartUp project (the one which is bold in the Solution Explorer).
If you set your Windows Phone project as StartUp project (right click on the project, and select "Set as StartUp project"), you will see the mentioned emulator options on the menu.
Other option is to right click on the project, select Properties, and in the Debug tab, select the desired Target Device.
