System.IO.FileNotFoundException for Microsoft.EntityFrameworkCore - nuget

I have a .NET Standard 2.0 project which uses EF Core via the Nuget package Microsoft.EntityFrameworkCore. Below is the relevant PropertyGroup from the *.csproj file:
<ItemGroup>
<PackageReference Include="Microsoft.EntityFrameworkCore" Version="2.1.4" />
<PackageReference Include="Microsoft.EntityFrameworkCore.Design" Version="2.1.4" />
</ItemGroup>
The solution builds, but at runtime, I get a System.IO.FileNotFoundException:
Could not load file or assembly 'Microsoft.EntityFrameworkCore, Version=2.1.4.0, Culture=neutral, PublicKeyToken=adb9793829ddae60' or one of its dependencies.
That assembly is not in the build folder (or any subfolders such as the netstandard2.0 subfolder). It is in %userprofile%\.nuget\ ...
I have tried:
Cleaning / Rebuilding
Clearing the Nuget cache.
Adding
<RestoreProjectStyle>PackageReference</RestoreProjectStyle> to the
*.csproj file.
Removing and re-adding Micrososft.EntityFrameworkCore (and Microsoft.EntityFrameworkCore.Design, which is also used)
Is there some other way of forcing the package to be included in the build folder (like Local Copy)?

Editing the *.csproj files and adding the following to a PropertyGroup seems to have fixed the problem (or at least provided a reasonable workaround):
<CopyLocalLockFileAssemblies>true</CopyLocalLockFileAssemblies>

Nuget not including mscorlib.dll

Nuget ignores adding references to a project when the DLL is named mscorlib.dll. Any way force nuget to add a references to the project, or copy the DLL to the bin output directory?
Here's the snippet from the .nuspec file:
<files>
<file src="..\..\bin\mscorlib.dll" target="lib\net45" />
</files>
The necessity is for deploying an alternative implementation of mscorlib.

What's the current impl. of NuGet stuff in .csproj?

I have a few solutions that started out in VS2008 or VS2010 or something like that. They contain some stuff that I think relate to NuGet package restore and including certain MS NuGet packages in the build process.
But this looks different in different projects, while I see no reason for any differences, and a new VS2017 project contains yet another different version.
So, what could I safely do to get my old projects up to date in this regard - what should it look like now, in VS2017?
Both old solutions contain a solution-level subfolder ".nuget" with three files: NuGet.Config, NuGet.exe and NuGet.targets.
The old .csproj files contain these "versions" of NuGet stuff:
Proj1:

</Target>
I would like to have the same setup for all these old projects (unless there would be specific reasons to differ), and I want the setup to be up to date with the tools and environment as per VS2017.
I have automatic package restore enabled and want to keep it that way.
Note: All four projects seem to build and run successfully. Proj2 and Proj3 are unit test projects. Proj1 is really two projects that are identical in this respect.
What's the current impl. of NuGet stuff in .csproj?
To resolve this question, you can follow below steps:
Close Visual Studio to avoid file potential file locks and conflicts.
If using TFS: Remove nuget.exe and nuget.targets from the solution's .nuget folder and remove those files from the solution workspace. Retain nuget.config with the disableSourceControlIntegration setting as explained in Omitting packages with Team Foundation Version Control.
If not using TFS: Remove the .nuget folder from the solution and the solution workspace.
Edit each project file in the solution, remove the <RestorePackages> element, and remove any references to the nuget.targets file.
<RestorePackages>true</RestorePackages>
And
<Import Project="$(SolutionDir)\.nuget\NuGet.targets" Condition="Exists('$(SolutionDir)\.nuget\NuGet.targets')" />
<Target Name="EnsureNuGetPackageBuildImports" BeforeTargets="PrepareForBuild">
<PropertyGroup>
<ErrorText>This project references NuGet package(s) that are missing on this computer. Enable NuGet Package Restore to download them. For more information, see http://go.microsoft.com/fwlink/?LinkID=322105. The missing file is {0}.</ErrorText>
</PropertyGroup>
<Error Condition="!Exists('$(SolutionDir)\.nuget\NuGet.targets')" Text="$([System.String]::Format('$(ErrorText)', '$(SolutionDir)\.nuget\NuGet.targets'))" />

Add custom DLL files in nuget package in new csproj

.nuspec file has section <files>, what are the alternatives for include localization resources for new csproj file? How to add custom DLL files?
The first part of the trick is to get your third party DLL added to the nupkg. This does it:
<ItemGroup>
<Reference Include="ThirdParty">
<HintPath>..\DLLs\ThirdParty.dll</HintPath>
</Reference>
</ItemGroup>
<ItemGroup>
<Content Include="$(OutputPath)\ThirdParty.dll">
<Pack>true</Pack>
<PackagePath>lib\$(TargetFramework)</PackagePath>
</Content>
</ItemGroup>
If you install this package into an old-style csproj then a reference to ThirdParty.dll will be added.
However, if you install this package into a new-style csproj then a reference to ThirdParty.dll will not be added as a referece, irritatingly. Work in progress...

NuGet package adds incorrect hint path

During an automated build, my nuget package needs to be non framework dependent, however I keep finding that the nuget package getting added is incorrectly adding a HintPath.
Within my nuspec I've defined the files that are part of the package:
<files>
<file src="lib\xyz.dll" target="lib\xyz.dll" />
<file src="lib\xyz.xml" target="lib\xyz.xml" />
</files>
However whenever I add the package to my project/solution, it incorrectly adds a hint path specifying:
<Reference Include="xyz, Version=11.0.0.0, Culture=neutral, PublicKeyToken=4a3c0a4c668b48b4">
<HintPath>..\packages\xyz.11.0.0.0\xyz.dll</HintPath>
<Private>True</Private>
</Reference>
This is causing the automated build server to not find the assembly and fail to build. I can manually fix the hint path, but would rather not.
I took a look at this post (Failed to add NuGet package) but I don't find it relevant. This post (NuGet package install uses specific assembly version in csproj files) seemed to be referring to the same problem but with no answer. Anybody have any thoughts?
You can work around this by using a custom MSBuild task.
Instead of adding the assembly to the lib directory create an MSBuild .targets file named after the package id and put your xyz assembly next to it.
\build
\Net45
\MyPackage.targets
\xyz.dll
\xyz.xml
Then in the MSBuild .targets file add the reference exactly how you want it to be. Something like:
<Project xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
<ItemGroup>
<Reference Include="xyz">
<HintPath>$(MSBuildThisFileDirectory)\xyz.dll</HintPath>
</Reference>
</ItemGroup>
</Project>
The above shows how to specify a hint path relative to the MSBuild .targets file. You said that you do want to use a hint path so you could remove that if xyz.dll can be resolved by MSBuild somehow, such as it being in the GAC.

On local host it is working fine.
But when I am hosting the published code it is giving me the above error.

It appears that Microsoft.Web.Infrastructure.dll is not being installed in the GAC, even if .net (4.0 or 4.5 or other) are installed successfully on Windows Server. On localhost (typically Windows client), it seems like it is being in the GAC when the tools/platform (Visual Studio etc.) are installed.
As one possible fix, please try the following:
Run the following command in the Package Manager Console. (If you are using Visual Studio, this can be reached via menu options "Tools --> Library Package Manager --> Package Manager Console:)
PM> Install-Package Microsoft.Web.Infrastructure
You will see the following messages if it is successfully installed.
Successfully installed 'Microsoft.Web.Infrastructure 1.0.0.0'.
Successfully added 'Microsoft.Web.Infrastructure 1.0.0.0' to Web.
You will notice that Microsoft.Web.Infrastructure.dll has now been added as a Reference (can be seen in the references folder of your project in in Solution Explorer)
If you look at the properties of this reference you will notice that "Copy Local" has been set to "True" by default.
Now when you "Publish " your project, Microsoft.Web.Infrastructure.dll will be deployed.
I installed MVC4 via WPI and it helped me.
I had the same problem. When I tried the accepted answer (rockyb), I got the message that the package was already installed and assigned to my project. When I checked the references list, it was NOT referenced, however.
The Microsoft.Web.Infrastructure was installed in my solution's packages folder. Instead of using NuGet to add the package, I just used the Add Reference option. On the left side of the pop-up window, I chose Browse, and then pressed the Browse button on the bottom of the window. I navigated to the packages folder under the folder that my solution was in, then drilled down to the ...\mysolution\packages\Microsoft.Web.Infrastructure.1.0.0.0\lib\net40 and clicked on the Microsoft.Web.Infrastructure.dll. After clicking OK, the package showed up in my References list. I used the Web Deploy Package option to deploy my website and everything worked.
Why not copy Microsoft.Web.Infrastructure.dll file manually to the server BIN folder. This works for. My project is VS2010 Website.
This file can be located:
C:\Program Files (x86)\Microsoft ASP.NET\ASP.NET MVC 4\Packages\Microsoft.Web.Infrastructure.1.0.0.0\lib\net40
Just copy and paste it in the BIN folder.
You probably need to include this in the web.config if you don't have it already
<compilation debug="true" targetFramework="4.0">
<assemblies>
<add assembly="Microsoft.Web.Infrastructure, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
</assemblies>
</compilation>

I found the problem. Instead of adding a class (.cs) file by mistake I had added a Web API Controller class which added a configuration file in my solution. And that configuration file was looking for the mentioned DLL (Microsoft.Web.Infrastructure 1.0.0.0).
It worked when I removed that file, cleaned the application and then published.
After installing Microsoft.Web.Infrastructure through Nuget-Package Manager
PM> Install-Package Microsoft.Web.Infrastructure
Copy the Microsoft.Web.Infrastructure.dll manually from the Nuget-Package folder on your web application and then paste it in your bin folder of your web application deployed on the web server.
packages\Microsoft.Web.Infrastructure.1.0.0.0\lib\net40\Microsoft.Web.Infrastructure.dll
It worked for me.
Update-Package -reinstall Microsoft.Web.Infrastructure didn't work for me, as I kept receiving errors that it was already installed.
I had to navigate to the Microsoft.Web.Infrastructure.1.0.0.0 folder in the packages folder and manually delete that folder.
After doing this, running Install-Package Microsoft.Web.Infrastructure installed it.
Note: CopyLocal was automatically set to true.
Sometimes needs to delete the package with force then reinstall it
its works for me.
try delete package
Uninstall-Package Microsoft.Web.Infrastructure -force
then install again
Install-Package Microsoft.Web.Infrastructure
I had the same problem and the "Microsoft.Web.Infrastructure.dll" appeared to be missing. I have tried few advises and installed MVC`s etc. and nothing helped. The solution was to install "Web Services Enhancements (WSE) 1.0 SP1 for Microsoft .NET" which includes Microsoft.Web.Infrastructure.dll.
Available at: http://www.microsoft.com/en-gb/download/details.aspx?id=4065
I had the same problem. I tried installing Visual Studio 2010 SP1 but it didn't worked.
Finally I get Microsoft.Web.Infrastructure.dll from the colleague. You can find the dll into your friends PC where the project is perfectly working. Try to search dll into Temp/Temporary ASP.NET Files. Go to Temp using %temp% into run window.
After getting dll into your pc, just add reference to your project and it will work.
Republishing the site fixed the issue for me.
Was facing the same issue and unfortunately nothing here was working. Finally, I came across this link: https://blogs.msdn.microsoft.com/jjameson/2009/11/18/the-copy-local-bug-in-visual-studio/
Turns out the solution is sort of dumb: set copy-local for the microsoft.web.infrastructure dll to False, then set it back to True.
By the way, I think what is happening is that there are two versions of the microsoft.web.infrastructure dll, one that is pre-installed in the GAC, and another one that is now a nuget package. I think one is masking the other, hence causing issues. In my particular case, on my build server, I need it to be copied over to a folder (this folder is then zipped and sent off to deployment). I guess the system had a copy locally and just thought "nah, it'll be fine"
I have a files only website. Added MVC 5 to webforms application (targeting net45). I had to modify the packages.config
package id="Microsoft.AspNet.Mvc" version="5.2.3" targetFramework="net45"
to
package id="Microsoft.AspNet.Mvc" version="5.2.3" targetFramework="net45" developmentDependency="true"
in order for it to startup on local box in debug mode (previously had the top described error). Running VS 2017 on Windows 7...opened through File > Open > Web Site > File (chose root directory outside of IIS).
I had the same problem after upgrading a bunch of NuGet packages.
I have tried all kinds of deleting, cleaning, resintalling described here and beyong to no avail. The references did not have Microsoft.Web.Infrastructure despite the NuGet manager showed it was installed.
The problem was solved by replacing:
<package id="Microsoft.Web.Infrastructure" version="1.0.0.0" targetFramework="net45" />
with
<package id="Microsoft.Web.Infrastructure" version="1.0.0.0" targetFramework="net46" />
in packages.config. The culprit is apparently "net45".
Visual Studio 2022 .net.4.8
I just run this and is solved
you can install this dll using nuget package manager
PM> Install-Package Microsoft.Web.Infrastructure -Version 1.0.0
