I have a few libraries with target framework netstandard20. These libraries are consumed by a few .net framework 4.6.1 libraries.
The IT department uninstalled the .NET Core 2.0 from the build server because of some security vulnerability. All the libraries that use netstandard20 are now failing with the following error:
C:\bamboo6104...>nuget restore
MSBuild auto-detection: using msbuild version '16.11.2.50704' from 'C:\Program Files (x86)\Microsoft Visual Studio\2019\BuildTools\MSBuild\Current\bin'.
C:\bamboo6104\xml-data\build-dir\BAM-CUS-JOB1...\netstandard\xxx.csproj : error MSB4236: The SDK 'Microsoft.NET.Sdk' specified could not be found.
The Build Server already has Visual Studio 2019. What version of SDK need to be installed for the build to pass? I have the following SDKs on my laptop:
Will installing 2.1.526 version resolve the build issue?
I can't upgrade the libraries to .NET 5 or 6 due to we have numerous libraries with the same problem and upgrade is not a priority.

Build fails with following error in the .net standard 2.0 project : [ResolvePackageAssets] C:\Program Files\dotnet\sdk\2.1.301\Sdks\Microsoft.NET.Sdk\targets\Microsoft.PackageDependencyResolution.targets(198, 5): Package System.Security.Cryptography.ProtectedData, version 4.4.0 was not found. It might have been deleted since NuGet restore. Otherwise, NuGet restore might have only partially completed, which might have been due to maximum path length restrictions.
What's interesting is I can't find reference or use of System.Security.Cryptography.ProtectedData anywhere in the project. Any help is greatly appreciated.
P.S - Can't use dotnet build, as the solution needs building of licenses.licx files, and the component which builds it (Microsoft.Build.Tasks.LC) is not ported to .Net Core. The suggestion from various posts was to use MsBuild.exe
I am trying to install NUnit 3.9 in Visual Studio 13 Professional, but I am facing the below mentioned error while installing:
'NUnit' already has a dependency defined for 'NETStandard.Library'.
How do I solve this issue?
This error is often caused by the fact that your version of NuGet is too old. Try updating NuGet.
NUnit's most recent NuGet packages include .NET Standard builds, which mean NuGet client version 2.12 or later is required. From the next version of NUnit, you'll get a more helpful error message for this.
If you cannot upgrade Visual Studio to a newer version that includes newer versions of NuGet, you can install NUnit 3.5.0 which doesn't include .NET Standard. You can select the older versions from a dropdown in the user interface, or install from the Package Manager Console.
Install-Package NUnit -Version 3.5.0
I'm trying to add AutoMapper as a dependency to a project using NuGet on Visual Studio Premium 2012, but it fails.
It says:
Operation failed
'AutoMapper' already has a dependency defined for
'Microsoft.CSharp'.
I'm able to add other dependencies.
I'm using the last version of the package manager for VS 2012:
NuGet Package Manager 2.8.60318.667
Any ideas what should I check?
The problem is that your NuGet Package Manager is too old. You need NuGet 2.12 since this supports the newer .NETStandard frameworks that the AutoMapper 5.0.1 NuGet package is using.
The AutoMapper has a group dependency which specifies a target framework of .NETStandard. Since your version of NuGet Package Manager is too old it does not recognise this target framework and converts it to an Unknown target framework and you end up with duplicate frameworks since there .NETStandard is used a few times in that NuGet package. This causes the error:
'AutoMapper' already has a dependency defined for 'Microsoft.CSharp'
Unfortunately NuGet 2.12 is not available for Visual Studio 2012 but is available for Visual Studio 2013.
So either you need to update to Visual Studio 2013 or above, or you will have to use the older AutoMapper NuGet package which does not support .NETStandard.
Seems to be a problem with the current version of automapper:
AutoMapper 5.0.0 Tuesday, June 28, 2016
I tried with the previous version and it works:
PM> Install-Package AutoMapper -Verbose
Install-Package : 'AutoMapper' already has a dependency defined for 'Microsoft.CSharp'.
At line:1 char:16
+ Install-Package <<<< AutoMapper -Verbose
+ CategoryInfo : NotSpecified: (:) [Install-Package], InvalidOperationException
+ FullyQualifiedErrorId : NuGetCmdletUnhandledException,NuGet.PowerShell.Commands.InstallPackageCommand
PM> Install-Package AutoMapper -Version 4.2.1
Installing 'AutoMapper 4.2.1'.
Successfully installed 'AutoMapper 4.2.1'.
So, if you can't update NuGet Package Manager, the answer is:
PM> Install-Package AutoMapper -Version 4.2.1
I ended up needing to update NuGet.exe that was included in the solution to be able to build NuGet packages by running:
nuget.exe update -self
I had the same issue on VS2013. I had to update to VS2013 Update 5 and get the latest nuget distro for VS2013 at
https://dist.nuget.org/visualstudio-2013-vsix/v2.12.0/NuGet.Tools.vsix
Once that was done, I rebooted Visual Studio. After that I was able to use the Automapper 5.0.2 package
Go to Visual Studio > Tools > Extension and Updates
Find Updates in left accordion menu, Go to Visual Studio Gallery.
You will find a update for Nuget.
Update the nuget package and try installing or builing the project.
Thanks,

An other workaround if you're stuck with VS2012 and the old Nuget version:
Find the Cache folder of VS 2012's Nuget Package Manager (with Tools - Options - Nuget Package Manager)
Open AutoMapper.5.x.x.nupkg with your favorite Zip Tool
Modify the file AutoMapper.nuspec - I simply deleted all dependencies except .NETFramework4.5
Add the cache folder as a Nuget source (also in Tools - Options - Nuget Package Manager)
Install Automapper either with the console or the GUI but make sure to choose first the newly added cache folder as package source.
Of course, the next version of Automapper probably needs to be adapted, too, in order to install it.
This looks like a mismatch between the .NET version used by the Automapper package and your project. Can you confirm the .NET version that your project is using?
Automapper 6.0.2 - nuget 2.8.8 gives this error. Needed to update to 3.4.4 to get this working.
Removed both CSharp and AutoMapper. Installed CSharp (4.0.0.0) first and then added Automapper (6.1.1.0). This resolved the problem for me.
I observed this exact problem when opening a project with Visual Studio 2010.
After opening with VS2017, I was able to install AutoMapper without any error.
With Visual Studio 2017 preview (latest version of VS 2017 Professional), in ASP.Net Core 2.0 project, I am trying to add a WCF service via Connected Services, and it gives the below error.
My teammate has the same project and it works on his computer but gives the below error on my pc. I cleaned the project, rebuild but the error is not fixed. What should I do? Is that error about WCF, or NuGet? I deleted and reinstalled NuGet but the error still occurs.

I change package source(tools->nuget package manager->manage nuget package
...) with nuget.org instead of visual studio package and it works
