Why this Exception is raise when i compile my ASP.NET MVC3 Application...
The type 'System.Web.Mvc.ModelClientValidationRule' exists in both 'c:\Program Files\Microsoft ASP.NET\ASP.NET Web Pages\v2.0\Assemblies\System.Web.WebPages.dll' and 'c:\Program Files\Microsoft ASP.NET\ASP.NET MVC 3\Assemblies\System.Web.Mvc.dll'

I read here, that it is possible to use elder Mono (4.8) to build project. How to do this?
I'm trying to follow the instructions in Microsoft's document Code Generation
in a Build Process to rebuild T4 templates on our build server. When
I build, template generation is failing with the error (the full MSBuild output
is later in this question):
error MSB4018: The "TransformTemplates" task failed unexpectedly.
error MSB4018: System.IO.FileNotFoundException: Could not load file or
assembly 'Microsoft.VisualStudio.TextTemplating.14.0, Version=14.0.0.0,
Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies.
The system cannot find the file specified.
I created a minimal project that reproduces the problem. The script
build.cmd simply executes MSBuild. When I run build.cmd from my
workstation, the build succeeds. It only fails on the build server.
Things I've tried:
Copied the MSBuild and Visual Studio assemblies to the build server, as
specified by the Code Generation document.
Added the Visual Studio assemblies to the GAC.
Set the VSSDK140Install environment variable to "C:\Program Files
(x86)\Microsoft Visual Studio 14.0\VSSDK\" (because that's how it's set on
my workstation).
Set HKLM\SOFTWARE\WOW6432Node\Microsoft\VisualStudio\14.0!InstallDir to
C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE\
I'm trying to avoid installing Visual Studio 2015, because that's a pretty
large dependency to add to our build server, and the Microsoft documentation
explicitly says this should be possible.
Copied assemblies to C:\Program Files (x86)
I've copied the following files to the build server, as specified in the Code
Generation document (these are all in the Program Files (x86) folder, since
that's where they are on my machine):
$(ProgramFiles)\MSBuild\Microsoft\VisualStudio\v*.0\TextTemplating
Microsoft.VisualStudio.TextTemplating.Sdk.Host.14.0.dll
Microsoft.TextTemplating.Build.Tasks.dll
Microsoft.TextTemplating.targets
$(ProgramFiles)\Microsoft Visual Studio 14.0\VSSDK\VisualStudioIntegration\Common\Assemblies\v4.0
Microsoft.VisualStudio.TextTemplating.14.0.dll
Microsoft.VisualStudio.TextTemplating.Interfaces.14.0.dll (several files)
Microsoft.VisualStudio.TextTemplating.VSHost.14.0.dll
$(ProgramFiles)\Microsoft Visual Studio 14.0\Common7\IDE\PublicAssemblies\
Microsoft.VisualStudio.TextTemplating.Modeling.14.0.dll
Added to the GAC
I saw it's failing trying to load
Microsoft.VisualStudio.TextTemplating.14.0.dll, and since that assembly is in
the GAC on my workstation I guessed maybe that was required, so I tried using
GAC Manager to add
Microsoft.VisualStudio.TextTemplating.14.0.dll to the GAC, but the error is
the same.

When I looked in file Microsoft.TextTemplating.targets, found out it uses registry keys to find folders who contain dlls:
<PropertyGroup Condition=" $(IncludeDslT4Settings)=='true' ">
<!-- Path to VS\Common7\IDE -->
<!-- Check the 32bit location first ; if that is empty, use the 64bit location. -->
<VsIdePath>$(Registry:HKEY_LOCAL_MACHINE\Software\Microsoft\VisualStudio\14.0#InstallDir)</VsIdePath>
<VsIdePath Condition=" $(VsIdePath) == ''" >$(Registry:HKEY_LOCAL_MACHINE\Software\Wow6432Node\Microsoft\VisualStudio\14.0#InstallDir)</VsIdePath>
<!-- Set the default location for the Dsl Designer install. -->
<DslDesignerInstallPath Condition=" $(DslDesignerInstallPath)=='' ">$(VsIdePath)Extensions\Microsoft\DSL SDK\Dsl Designer\$(VisualStudioVersion)\</DslDesignerInstallPath>
<!-- Add the standard DSL templates folder -->
<IncludeFolders>$(IncludeFolders);$(DslDesignerInstallPath)TextTemplates\</IncludeFolders>
So I have to install Microsoft Visual Studio 2015 SDK and Microsoft Visual Studio 2015 Visualization & Modeling SDK on build server to registry DLLs.
However, Starting in Visual Studio 2015, you do not install the Visual Studio SDK from the download center. It is included as an optional feature in Visual Studio setup. So we could not install Visual Studio SDK without installing Visual Studio. see Visual Studio SDK for detail info.
Besides, Daniel's has a blog about How to transform T4 templates on build without installing a Visual Studio SDK, you can check if that give any helps.
The problem seemed to be that .NET could not find the assembly Microsoft.VisualStudio.TextTemplating.14.0.dll.
So instead of keeping everything in separate folders as Visual Studio installs them, I took the following files:
C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio\v14.0\TextTemplating
Microsoft.VisualStudio.TextTemplating.Sdk.Host.14.0.dll
Microsoft.TextTemplating.Build.Tasks.dll
Microsoft.TextTemplating.targets
C:\Program Files (x86)\Microsoft Visual Studio 14.0\VSSDK\VisualStudioIntegration\Common\Assemblies\v4.0
Microsoft.VisualStudio.TextTemplating.14.0.dll
Microsoft.VisualStudio.TextTemplating.Interfaces.14.0.dll (several files)
Microsoft.VisualStudio.TextTemplating.VSHost.14.0.dll
C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE\PublicAssemblies\
Microsoft.VisualStudio.TextTemplating.Modeling.14.0.dll
And copied them all into the MSBuild task directory:
C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio\v14.0\TextTemplating
After doing this, .NET was able to find the assemblies it needed and transformed the templates.

I'm using Xamarin 4.6.0.297 and Visual Studio 2015.
Is this an issue in StructureMap or Xamarin?
Update:
The seems to be an issue with the Linker and different versions of NetStandard Library. StructureMap is setup as a supporting .Net45, NetStandard 1.3 and NetStandard 1.5 in the nuget, when added NetStandard Lib 1.6 is being brought in and unless you update the packages to NetStandard Lib 2.0 (and its matching libraries), you will receive the Mono.Cecil error:
Mono.Cecil.ResolutionException: Failed to resolve System.Runtime.Loader.AssemblyLoadContext System.Runtime.Loader.AssemblyLoadContext::get_Default()
Note: I'm not sure if this is a problem with Mono.Cecil, the way StructureMap is packaged or the way Xamarin handles the nuget references...
LinkDescription:
A linker configuration like the following will get you around the issue:
<linker>
<assembly fullname="StructureMap">
<namespace fullname="StructureMap.*" />
</assembly>
</linker>
Just add an XML file to your project with the contents from above and assign a build action of LinkDescription to it.
Note: Using AndroidLinkSkip to skip the assembly will not work...
For me, adding a LinkDescription file, using AndroidLinkToSkip, and updating to .NETStandard 2.0 all did not work. Instead, I downgraded StructureMap to 4.4.0 as suggested by https://github.com/structuremap/structuremap/pull/597. That seems to have resolved the issue

I'm using Visual Studio 2015 with Xamarin extension for Visual Studio v4.2.2.11 (file Xamarin.VisualStudio_4.2.2.11.msi), Xamarin Android v7.0.2.42, MSBuild 2015 and .NET Reactor. Project is setup to use .NET FX v4.6.1 and Android Target v5.1 (API 22) and minimum version v4.4 (API 19).
Since I was getting this on my project, I tested this by creating a blank Android project without any code added to it, just the code created by the new blank project (button click) so there are no references to DLLs or 3rd party components.
Regards,
NCruz
I credit this answer to Lex Li who pointed out that I should try to disable each of the obfuscation features, and see which triggers the linker issue. There are several command line switches that I use to activate certain obfuscation features like so: -suppressildasm 1 -obfuscation 1 -stringencryption 1 -antitamp 1 ..etc. At first, I removed/deleted them all from the command line but it still had the error. Then I put them all back and instead put 0 instead of 1 (-suppressildasm 0) to deactivate each function. The suppressildasm feature was the one causing the error.
I am using:
VS Community 2015 edition, Xamarin v4.2, Xamarin.Android v7
It Shows:
