I have added a reference for "Xamarin.ios" to my project and it is working fine locally. I have committed the code and made a build for it in appcenter but it is failing and showing me error as mentioned below.
/Users/runner/work/1/s/Project/ViewModels/OrderViewModel.cs(19,7): error CS0246: The type or namespace name 'Foundation' could not be found (are you missing a using directive or an assembly reference?) [/Users/runner/work/1/s/Project/Project.csproj]

Time Elapsed 00:00:08.79
##[error]Error: The process '/Library/Frameworks/Mono.framework/Versions/6_12_11/bin/msbuild' failed with exit code 1
I have also tried with various mono versions but it did not work for me. Can you please suggest me the solution for the same?
Ensure that Xamarin.iOS has referenced in iOS project not shared prject, because netstandard project can't use any API specific to Xamarin.iOS .
Open your iOS csproj file to check if <Reference Include="Xamarin.iOS" /> exists there .
Refer to https://github.com/xamarin/xamarin-macios/issues/10191 .
I have a Pipeline using YAML in Azure DevOps. I have the following task in my YAML file:
- task: XamariniOS#2
inputs:
solutionFile: '**/*iOS.csproj'
configuration: 'Release'
packageApp: false
runNugetRestore: false
I receive the following errors when the Pipeline runs:

I'm able to build the iOS project manually successfully in Visual Studio. I have tried removing and re-adding project references but it hasn't seemed to help.
My project is setup like the following:
Do I need to configure something differently for Azure DevOps?
I have a xamarin project that uses some components that are not recognized.
When I try to compile this project it gives the following error:
Error CS0246: The type or namespace name "UIKit" can not be found (is it missing a using directive or an assembly reference?)
Error CS0246: The name of the "CoreLocation" type or namespace can not be found (is it missing a using directive or an assembly reference?)
Anyone have any ideas to solve this?
I'm pretty new to OS X (4 days with my new mac), and I am working on setting up an environment where I can debug my Asp.Net 5 web project locally with the debugger built into Visual Studio Code, specifically getting the breakpoint to work when attaching to mono.
I followed these instructions for installing asp.net 5 and visual studio code. (http://docs.asp.net/en/latest/getting-started/installing-on-mac.html)
I then installed yeoman, and scaffolded out an aspnet project.
I ran commands dnu restore, dnu build, and dnx web.
The project runs locally on Kestrel at localhost:5000 just fine. I can also attach it to mono via the VS Code debugger.
The issue arises when I try to set breakpoints in the C# code. The debugger will not hit them.
After doing some research I found that I needed to specify the Startup.cs file to mono as the one to debug. (https://code.visualstudio.com/Docs/editor/debugging)
But after running mcs -debug Startup.cs, I get these errors:
Startup.cs(5,17): error CS0234: The type or namespace name `AspNet' does not exist in the namespace `Microsoft'. Are you missing an assembly reference?
Startup.cs(6,17): error CS0234: The type or namespace name `AspNet' does not exist in the namespace `Microsoft'. Are you missing an assembly reference?

It looks like mono cannot debug compile the Startup.cs properly. Is anyone else getting this error when trying to set up debugging? Or does anyone have breakpoints working with mono, asp.net 5, kestrel, vs code, and OS X?
Debugging Visual Studio Code and ASP.NET 5 are in preview and at this
time debugging ASP.NET 5 is not supported in Visual Studio Code (on
any platform). Rest assured, we are working hard to bring these
experiences to you in the near future.
Ref: https://code.visualstudio.com/docs/runtimes/ASPnet5
The Mono section that you are referring to is for compiling and attaching to a mono/.Net program (not an dnx ASP.NET-based one). ASP.NET 5 applications are compiled using the Roslyn compiler, not Mono's mcs.
Debugging a Mono Application Example:
Create a directory, cd into it and type code . to start VSCode using that directory.
mkdir monoconsoletest
cd monoconsoletest
code .
Create a new file in VSCode
Name it program.cs
Enter the following code into the editor:
using System;
namespace consoleViaVSCode
{
class MainClass
{
public static void Main (string[] args)
{
Console.WriteLine ("Hello VSCode!");
}
}
}
You could compile and run this in a shell, but let create a tasks.json file so we can do it via the Command Palette.
Create a tasks.json file:
The next step is to set up the task configuration. To do this open the Command Palette with F1 and type in Configure Task Runner, press Enter to select it.
This will create a sample tasks.json file in the .vscode folder. The initial file has a large number of examples within it. Highlight it all, delete it and add:
{
"version": "0.1.0",
"command": "mcs",
"isShellCommand": true,
"showOutput": "silent",
"args": ["-debug", "program.cs"]
}
Now you have one task that you can execute via task mcs down the Command Palette and this task will build your program.cs using Mono's mcs compiler with the '-debug' option that will create a program.exe.mdb file that has the debugging symbols for the program.exe application.
So execute that task and if you have no errors, a program.exe and program.exe.mdb` will show up in the file pane:
If you have any errors, they will show up in the Output pane (right of the source code pane).
Now lets add a task to run your program with mono .Net runtime with the options for it to wait for a debugger to attach.
Note: I would show you a mono debugger task but running a shell process like that is broken in VSC 0.10.1. and you would be to wrap it in a glup routine... :-/ so...
In the process.cs, set a break point on the Console.Write.... line:
From the shell that you started VSCode from:
mono --debug --debugger-agent=transport=dt_socket,server=y,address=127.0.0.1:5858 program.exe
Back in VSCode:
Click the Bug Icon and than the Config\Gear Icon and select "C# mono" to generate the default "attach" configuration. Select "Attach" and click green Start button:
And you will hit your breakpoint:
I'm having an odd problem on my build server. I'm using the latest version of TeamCity on Windows Server 2008 R2. I used the web platform installer to install ASP.NET MVC on the build server but, my compilation is still failing with messages that it cannot find the System.Web.Mvc.dll. I've verified that it is on the disk at the expected location:
(C:\Program Files (x86)\Microsoft ASP.NET\ASP.NET MVC 3\Assemblies)
Here is a selection of the messages:
Controllers\AccountController.cs(7, 18): error CS0234: The type or namespace name 'Mvc' does not exist in the namespace 'System.Web' (are you missing an assembly reference?)
Controllers\AccountController.cs(15, 35): error CS0246: The type or namespace name 'Controller' could not be found (are you missing a using directive or an assembly reference?)
Controllers\HomeController.cs(5, 18): error CS0234: The type or namespace name 'Mvc' does not exist in the namespace 'System.Web' (are you missing an assembly reference?)
Controllers\HomeController.cs(9, 32): error CS0246: The type or namespace name 'Controller' could not be found (are you missing a using directive or an assembly reference?)
Global.asax.cs(5, 18): error CS0234: The type or namespace name 'Mvc' does not exist in the namespace 'System.Web' (are you missing an assembly reference?)
Models\AccountModels.cs(8, 18): error CS0234: The type or namespace name 'Mvc' does not exist in the namespace 'System.Web' (are you missing an assembly reference?)
So what am I missing?
The errors you seem to be inferring that it can't find the correct version of the MVC dll. Is it possible you've installed the MVC (original) or MVC2 instead of the MVC3 from the web platform onto the build server?
Edit:
Also the file should be in the GAC, (not sure the location on Win Server 2008 but guessing it's similar to Win 7.)
C:\Windows\Microsoft.NET\assembly\GAC_MSIL\System.Web.Mvc\ (then the .Net version folder, mine is v4.0_3.0.0.0)
