Just a few days ago got this error, after updating to Visual Studio Community 2022 v17.2 (from v17.1.6):
Error NETSDK1005
Assets file 'C:.........XXXXXX.Web\obj\project.assets.json' doesn't have a target for 'net6.0'. Ensure that restore has run and that you have included 'net6.0' in the TargetFrameworks for your project. XXXXXX.Web C:\Program Files\dotnet\sdk\6.0.300\Sdks\Microsoft.NET.Sdk\targets\Microsoft.PackageDependencyResolution.targets 267
Uninstalled everything related with VS2022 + Installer
Rebooted
Fresh Git Cloned the project I'm working on (I work on several computers all with Win 10 and all with the latest updates, this is the only VS installation that presents this problem)
Reinstalled VS 2022 v17.2 (with .NET 6.0, the usual install)
The .csproj file has everything in place:
<PropertyGroup>
<TargetFramework>net6.0</TargetFramework>
<RuntimeIdentifiers>win-x86;win-x64</RuntimeIdentifiers>
<IsPackable>false</IsPackable>
<SpaRoot>ClientApp\</SpaRoot>
<DefaultItemExcludes>$(DefaultItemExcludes);(SpaRoot)\**\node_modules\**;</DefaultItemExcludes>
<AspNetCoreHostingModel>OutOfProcess</AspNetCoreHostingModel>
</PropertyGroup>
Always delete the 'bin' and 'obj' folders before build or rebuild....
Cannot get away with the compilation, and always receiving that NETSDK1005 error...
Getting desperate :(
Thanks in advance for any help
P.S. - already checked question 70711153
I found the problem and it indeed had to do with restoring NuGet Packages, in that I have a connection to a corporate NuGet repository, and the call to it was breaking due to wrong credentials.
What was troubling was that the error did not identify the nature of problem with the connection or the username of the credentials getting refused.
On the logged in user popup dialog window, where the several used usernames are presented, there was one username that was required to re-enter its password.
That was all it took.
Visual Studio > Tools > Options > Azure Service Authentication. ReBuild and the NuGet Packages will be restored and build successful.
We had this issue in our Azure DevOps pipeline and it ended up being that the "NuGet Restore" task was using an old version of NuGet. You can see which version the pipeline is using if you check the logs for the "NuGet Restore" task and look for the "Detected NuGet" line.
We:
added in the "NuGet Tool Installer" task before the "NuGet Restore" task
Under the "Version of NuGet.exe to install", list the version you want to use, or the minimum version (e.g. >=6.1.0)
(this step is possibly overkill) Under the "NuGet Restore" Task, check "Disable local cache"
This happens because NuGet writes a file named project.assets.json in the obj\ folder & the .NET SDK uses it to get information about packages to pass into the compiler. In .NET 5, Nuget added a new field called TargetFrameworkAlias, and thus in MSBuild versions < 16.8 or NuGet versions < 5.8, it is possible that you can generate an assets file without the TargetFrameworkAlias as it will read the property and not find it.
You can resolve this issue by ensuring you are on MSBuild version 16.8+ & using NuGet version 5.8+.
In my case I have commented out the TargetAlias line and it published successfully.

For me, I was getting this when updating my projects from .NET Core 3.1 to .NET 6. I had my .NET 6 code in another Git branch and when I switched from the main 3.1 branch to the 6 branch and then tried to build the solution, I would get that message.
After some trial and error, the solution that worked for me was doing the Git checkout and the restore via command line.
Close the solution
From the Developer Powershell (or using regular Powershell or the Visual Studio 2022 Command Prompt), navigate to the local directory that has your repo, and then:
git checkout [branch name]
dotnet restore
Then back in Visual Studio, reopen the solution and build, which would work.
For me, this happened after switching from .net6.0 to .net 7.0 in asp.net core / blazor project. The error occured when trying to publish the project to IIS.
Solution was to switch the "target framework" in the publishing configuration (.pubxml) in the "Publish"-tab.
For me this fix worked:
If you don't have the dotnet cmd line tool, download and install the .NET 6 SDK.
Open a cmd prompt and run the command:
dotnet restore <path to your solution>
(for instance: dotnet restore c:\app\myapp.sln)
nuget restore resolved the same issue
and/or dotnet restore
I had this bug in a solution with several SDK plus non-SDK C# projects.
What fixed my case:
Close the solution.
Separately open the first project of the solution that Visual Studio failed to build.
Build the project. --> "Error not found and build is OK"
Reopen solution. --> "Error disappeared"
I got the same error when publishing Web API to the cloud.
Use Tools ->Command line -> Developer command prompt in Visual Studio 2022, enter AZ login, and after login, restart the visual studio, it is working for me again.
Had the same problem in Azure Devops, using a Windows 2019 build server with VisualStudio 2022
Error:
##[error]C:\Program Files\dotnet\sdk\6.0.301\Sdks\Microsoft.NET.Sdk\targets\Microsoft.PackageDependencyResolution.targets(267,5): Error NETSDK1005: Assets file 'C:\agent\vso_work\4\s<..>.API\obj\project.assets.json' doesn't have a target for 'net6.0'. Ensure that restore has run and that you have included 'net6.0' in the TargetFrameworks for your project.
Resolved by adding a "NuGet Tool Installer" using version >=6.0.0
Before the NuGet restore task
enter image description here
we got this problem when added cache on gitlab, and started to use dotnet restore,
it happend because we missed the "runtime" parameter to the restore command,
- dotnet restore --packages .nuget --runtime win-x64
- dotnet publish --no-restore --runtime win-x64
In my case the problem was I had updated the Nuget package version in one assembly but not in another, so check you have the same nuget package versions across your solution.
For me, it works to set the target framework to another framework like .NET Core 3.1, build the application, set the framework to the original framework and rebuild.
In my case I had inadvertently added a couple of projects to the solution that were in another folder. I received no errors until I changed NET version from NET6.0 to NET6.0-windows on one of the projects. The solution then didn't build, with 100s of errors, but each individual project built OK.
I noticed that "project.assets.json' doesn't have a target" error among all the errors, pointing to the outside folder.
Bringing those projects into the solution folder fixed the error.
I got the same error sometime back. This worked for me: Logout from visual studio and login to visual studio account
I had an error:
Ensure that restore has run and that you have included 'net6.0' in the
TargetFrameworks for your project. You may also need to include
'win10-x64' in your project's RuntimeIdentifiers.
I removed bin and obj folders for this project and rebuilt the project. dotnet clean, dotnet restore didn't work for me.
I had the same problem ("...\obj\project.assets.json' doesn't have a target for 'net6.0'. Ensure that restore...") with clean batch compilation of my sln: msbuild 17.4, nuget 4.7.
I replaced string
nuget.exe restore my.sln
with string
msbuild.exe my.sln /t:Restore
that was before
msbuild.exe my.sln /t:Build
and everything worked.
I got the same error this morning.
This worked for me: right click on solution explorer in visual studio -> 'Restore NuGet Packages'.
Hope this helps.
I uninstalled Visual Studio 2019 and installed it as 2022.
I reinstalled Flutter.
When building Flutter desktop, the following problem is repeated.
If I run it in another project, it works without any problem.
Launching lib\main.dart on Windows in debug mode...
Building Windows application...
Nuget is not installed.
Nuget.exe not found, trying to download or use cached version.
1- make sure you have installed Visual Studio
2-
NuGet Package Manager (PM UI and PM Console) is included with Visual
Studio. The latest NuGet releases are delivered as part of Visual
Studio updates.
HOWEVER: nuget.exe itself is not included with any version of Visual Studio.
so you need to download the latest NuGet Windows x86 Commandline from https://www.nuget.org/downloads
3- put it inside the flutter sdk folder or any folder you like
4- copy the folder path
5- in windows serach, search for env so you can put it as system variables. edit path with a new line and past the folder path
6- restart android studio
7- congrats
there's a video on youtube for the exact steps:

Although I don't know why it would work without this error message on the same machine, I recently ran into this issue as well. The way I fixed it was to download the nuget executable and add it to my path.

Project: Portable library for Xamarin.iOS project
I have added newtonsoft.json package, so when I open project in visual studio it generates project.lock.json and the build works fine. But when I try to run from command line it is not working.
Can you please suggest what command should I use to generate this file?
The project.lock.json file is created during the NuGet package restore. This will be done automatically by Visual Studio.
From the command line you can generate the project.lock.json by one of the following:
nuget restore /path/to/yoursolution.sln
msbuild /t:restore /path/to/yoursolution.sln
Both of the above will recreate the project.lock.json file. Then you can build the solution.
Is it possible to build a Visual Studio 2015 extension project on a build server (TeamCity agent) without Visual Studio installed? What kind of SDK do we need to install?
At the moment we receive the following error message:
error MSB4019: The imported project "C:\Program Files (x86)\MSBuild\Microsoft\Portable\v4.6\Microsoft.Portable.CSharp.targets" was not found. Confirm that the path in the declaration is correct, and that the file exists on disk.
So there is definitely some kind of SDK missing.
Microsoft.VSSDK.BuildTools
Contains targets and tools to enable the building of managed VSIX
projects without VSSDK MSI installed. Only for VS 2015 and onwards
Additional packages that may be of interest:
https://www.nuget.org/profiles/VisualStudioExtensibility
Using #weir's answer almost worked - the project built successfully, but it failed to produce a VSIX container at the end. For some reason the Nuget package hadn't added the necessary Import to the .csproj to bring in the VsSDK.targets, so the VSIX targets were missing and never got executed.
Here are the steps which worked for me:
Edit the VSIX project .csproj file, and remove Import Project="$(VSToolsPath)\VSSDK\Microsoft.VsSDK.targets" Condition="'$(VSToolsPath)' != ''" />. This will fail on the build server where the VSSDK doesn't exist in the VSToolsPath.
In the VS2015 IDE, open the Nuget Package Manager for the project, and install Microsoft.VSSDK.BuildTools (I used v14.3.25407)
Back in the .csproj file, find the import which the Nuget package added, e.g. <Import Project="..\packages\Microsoft.VSSDK.BuildTools.14.3.25407\build\Microsoft.VSSDK.BuildTools.targets" .../> and add another one below it for the VsSDK.targets file (inside the tools directory), <Import Project="..\packages\Microsoft.VSSDK.BuildTools.14.3.25407\tools\vssdk\Microsoft.VsSDK.targets" .../>
It looks like you have to install the Portable Library Tools on the build agent. You can download them from the VS Gallery and install them without having VS on the build agent using the following parameter /buildmachine.
Download Microsoft Build Tools 2015
I'm currently setting up project in Visual Studio Online (VSO) and having troubles with setting up automated build.
My solution contains projects targeted as Universal Windows
VSO uses msbuild to run my project.
During build I see strange error messages like:
Error CS0518: Predefined type 'System.Void' is not defined or imported
Error CS0518: Predefined type 'System.Object' is not defined or imported
Error CS0246: The type or namespace name 'Uri' could not be found (are you missing a using directive or an assembly reference?)
msbuild is invoked with following parameters:
C:\Program Files (x86)\MSBuild\14.0\bin\amd64\msbuild.exe "C:\a\b0d9e3fd\test\src\Shipping.sln" /nologo /m /nr:false /fl /flp:"logfile=C:\a\b0d9e3fd\test\src\Shipping.sln.log" /dl:CentralLogger,"C:\LR\MMS\Services\Mms\TaskAgentProvisioner\Tools\agent\worker\Microsoft.TeamFoundation.DistributedTask.MSBuild.Logger.dll"*ForwardingLogger,"C:\LR\MMS\Services\Mms\TaskAgentProvisioner\Tools\agent\worker\Microsoft.TeamFoundation.DistributedTask.MSBuild.Logger.dll" /p:Platform=Win32 /p:TargetVersion=”Windows10” /p:TargetPlatformVersion=”10.0.10010.0” /p:platform="any cpu" /p:configuration="release" /p:VisualStudioVersion="14.0"
What's wrong with this? Are there any other additional parameters required to build universal windows app with msbuild?
Are you targeting the Windows 10 SDK? If so note that it is not installed on the TFS hosted build servers. Consequently you will not be able to build apps that use the Windows 10 SDK. You can see the complete list of installed software here.
Just found the solution.
If build UWP app, from VS it resolves NuGet dependencies automatically. By default VS 10 projects uses NuGet of 3rd version, which was not installed on our build machine. That's why we had such issue.
The problem was fixed with installing NuGet 3 onto build agent and configure script which resolves NuGet packages before build.
If you can't customize the software of your build agent (aka: the free Hosted Agent) another work-around is to just check in your project.lock.json file.
This is because NuGet v2.8.7 can read both project.json and project.lock.json files but it cannot generate a project.lock.json file from a project.json file.
And, if at such a time Microsoft updates NuGet for their default build agents, you can just remove it from source-control and let it generated automatically as part of Nuget -restore. Until then, just check it in.
