I am trying to build a project using Visual Studio 2019 and C# but it fails.
CSC : error SI0001: Object reference not set to an instance of an object.
There is not any specific info and I do not know where to look at. I will appreciate some help.
PS: I did not change anything in this project and it works for my colleague.
thank you in advance

My solution consists of 3 projects:
My backend project with assembly My_Test_App (portable)
My_Test_App.Android
My_Test_App.iOS
I develop using VS2015 and use mac to build and deploy. It works fine in iOS simulator. My iOS project do not use linker. Also i have LLVM and incremental build already unchecked.
But when i tried to debug to iPhone device, i got this error:
Severity Code Description Project File Line Suppression State
Error Could not AOT the assembly/Users/myMacName/Library/Caches/Xamarin/mtbs/builds/My_Test_App.iOS/c7eaf4168fcb1f8aaecd3a6cbb0f37ee/obj/iPhone/Release/mtouch-cache/64/Build/My_Test_App.dll' My_Test_App.iOS
My question is:
How do you disable the AOT in the Xamarin.iOS project? When i check the csproj file of the iOS project, it does not have like in the droid project.
Is disabling the AOT the correct way to solve it?
Thank you for answering!

You cannot disable AOT on iOS, your project won't work as iDevices do not allow JIT'ing
No unfortunately no.
We'd need a longer build log (add '-v -v -v' as 'mtouch' arguments), but it can happen because the assembly is too big. you might want to enable Linking All Assemblies in the iOS project settings.

I used process Monitor to check, which executable gets invoked. it Looks like it really invokes the vs2008 executables...

Any idea, how to solve this?

on my work computer, The VS Default templates for c++ produce build Errors. (VS2010, VS2012, VS2013)
It Kind of Looks like it invokes an old Version of the Compiler (unknown Option '/sdl', where sdl probably stands for security development LifeCycle, which has been added with vs2012, if i remember correctly)

No idea if it helps, but here is a list with all installed MS Software:
https://skydrive.live.com/redir?resid=5062EFE7E0C8ECCC!2721&authkey=!APk3skYPRCffPWQ&ithint=folder%2c
Ok, i found the solution myself.
similar to this (http://social.msdn.microsoft.com/Forums/de-DE/baf613fc-3b24-4f47-9800-38499965e9dc/vs2010-is-using-a-wrong-compiler-Version) question, my "Microsoft.Cpp.Win32.user" property sheet contained references to the vs2008 directories. i have no clue how they got there, but removing them solved my problem.
open View -> Other Windows -> Property Manager
double click on Microsoft.Cpp.Win32.user
go to VC++ Directories
rows which have been changed are bold. on all bold rows, click inside the text field, then on the Dropdown menu select inherit from parent or Project Defaults
I verified that it now uses the correct Compiler by compiling the following snippet:
auto asd = std::make_unique<int>();
make_unique has been added with VS2013.
Anyone have a clue, what changed These values?
The difference between libwinutils.vcxproj and winutils.vcxproj shows the problem.
<Import Project="$(VCTargetsPath)\Microsoft.Cpp.props" /> appears before Release|Win32 PropertyGroup.
<Import Project="$(VCTargetsPath)\Microsoft.Cpp.props" />
<PropertyGroup Condition="'$(Configuration)|$(Platform)'=='Release|Win32'" Label="Configuration">
<ConfigurationType>Application</ConfigurationType>
<UseDebugLibraries>false</UseDebugLibraries>
<WholeProgramOptimization>true</WholeProgramOptimization>
<CharacterSet>Unicode</CharacterSet>
<PlatformToolset>v110</PlatformToolset>
</PropertyGroup>
Open winutils.vcxproj, and move <Import ...> after Release|Win32 PropertyGroup, like the following quote:
<PropertyGroup Condition="'$(Configuration)|$(Platform)'=='Release|Win32'" Label="Configuration">
<ConfigurationType>Application</ConfigurationType>
<UseDebugLibraries>false</UseDebugLibraries>
<WholeProgramOptimization>true</WholeProgramOptimization>
<CharacterSet>Unicode</CharacterSet>
<PlatformToolset>v110</PlatformToolset>
</PropertyGroup>
<Import Project="$(VCTargetsPath)\Microsoft.Cpp.props" />
I have successfully built winutils of hadoop-2.7.0-src with VS2012 toolset.

If your compiling a windows project then make sure you have the application type selected as 'Windows Application' not 'Console Application'.
Also, VS uses wWinMain if you want to use Unicode.
