MSBUILD throws error: The SDK 'Microsoft.NET.Sdk' specified could not be found

I'm trying to build a solution using msbuild command line and I keep getting this error:

error MSB4236: The SDK 'Microsoft.NET.Sdk' specified could not be found.

The version of msbuild is the latest from microsoft visual studio 2017 tools. I'm using Windows Server 2012 R2 and the project uses .NET Core 2.0.

This is the command that I'm using:

msbuild.exe /p:Configuration=Release /t:restore C:\Projects\MyProject.sln

Navigate to the file explorer => this PC => windows (C:) => Program files => dotnet and verify is SDK folder there or not

Now select program files (x86) > dotnet (check if you have a sdk folder here a). If you don't find SDK folder here, Copy the complete SDK folder from Program file's dotnet and paste it into Program files (x86)'s dotnet folder

In my case this error was caused by a nearly empty SDK directory under %ProgramFiles%\dotnet\sdk. It was left there after I installed and uninstalled a later SDK version and deleting it manually fixed the issue.

I had VS 2019 Professional, VS 2022 Professional and VS 2022 Community versions. I uninstalled VS 2022 Professional and .NET Standard projects builds started to fail, but only when I built them from the console. The error was "The SDK 'Microsoft.NET.Sdk' specified could not be found." From VS 2022 the build succeeded.

So finally I noticed that the environment variables' path no longer contained C:\Program Files\Microsoft Visual Studio\2022\Community\MSBuild\Current\Bin. I added it and the issue was solved.

I had the same problem, which was solved by updating Visual Studio. I wanted to upgrade the project to .NET 8 but I was getting this error. My version was 17.5.2, I updated it to 17.9.3.

In case it helps somebody else.

In my case I was trying to add a reference to some projects of the prism library solution, prism. Forms and prism.dryloc.forms. I was also getting the error mentioned in this thread. After searching for a solution, I came across this page:

https://github.com/novotnyllc/MSBuildSdkExtras

Afer reading this line here:

Adding a global.json containing the Sdk name and version.

I pasted in my solution the same global.json file the prism library solution had which allowed me to reference the projects.

I was working on a .NET Core 6 project and encountered the mentioned error

The SDK 'Microsoft.NET.Sdk' specified could not be found.

when trying to load a project file using new

Microsoft.Build.Evaluation.Project("path") 
or 
Microsoft.Build.Project("path")

The issue persisted even after setting the MSBuildSDKsPath environment variable.

My Resolution: Utilize MSBuildLocator The issue stems from the way MSBuild interacts with .NET Core SDK-style projects. In .NET Core, unlike the traditional .NET Framework, MSBuild requires additional setup to correctly locate and use the SDK and its associated properties.

Solution Steps: Use MSBuildLocator:

The key to resolving this issue is to use the MSBuildLocator package. This package dynamically discovers and loads the MSBuild assemblies from the .NET Core SDK, ensuring that all necessary components are correctly referenced. Register MSBuildLocator Before Any MSBuild Reference:

It's crucial to call MSBuildLocator.RegisterDefaults() before making any calls to MSBuild APIs. This registration must be the first operation in your application concerning MSBuild. Handling NuGet References:

When referencing Microsoft.Build and Microsoft.Build.Utilities.Core in your project, it's important to set the attribute ExcludeAssets="runtime" in your .csproj file. This prevents a runtime conflict since MSBuildLocator will provide the necessary assemblies at runtime.

Example:

  <ItemGroup>
      <PackageReference Include="Microsoft.Build" Version="17.3.2" ExcludeAssets="runtime"/>
      <PackageReference Include="Microsoft.Build.Locator" Version="1.6.10" />
      <PackageReference Include="Microsoft.Build.Utilities.Core" Version="17.3.2" ExcludeAssets="runtime" />
  </ItemGroup>

And in your C# code:

using Microsoft.Build.Locator;

// This should be the first MSBuild-related call in your application
MSBuildLocator.RegisterDefaults();

// Now you can safely use MSBuild APIs
var msProject = new Microsoft.Build.Evaluation.Project(projectFilePath);

Important Notes:

• The MSBuildLocator.RegisterDefaults() must be called before any usage of MSBuild APIs to avoid any exceptions.

• The exclusion of runtime assets is crucial to prevent compile-time exceptions due to conflicts between the MSBuildLocator-provided assemblies and the ones referenced in the project.

If you have different versions of Sdks installed in your system, then updating environment variable must be using and old Out-Of-Support version of Sdk.

Under "User variable" section look for "MSBuildSDKsPath" and update the latest version Sdk path

I installed a different version of Visual Studio and then my projects were able to load.

Previously, I installed 17.6, which did not work for my projects. Then I installed 17.4 and that worked.

I tried almost all in this thread without success. I was able to fix the issue by changing the PATH environment variable. I had "C:\Program Files (x86)\dotnet" and after "C:\Program Files\dotnet". The solution was to put "C:\Program Files (x86)\dotnet" after "C:\Program Files\dotnet". Solved!

I ran into this issue after installing .NET 7 to work with gRPC. After uninstalling .NET 7 the IDE was still looking for it. I deleted the empty C:\Program Files\dotnet\sdk\7 folder. I closed an opened the project it found the lastest .NET 6 installation.

I encountered the same error and to fix it I installed .NET 6.0 SDK. https://dotnet.microsoft.com/en-us/download/visual-studio-sdks

I only had .NET 7.0 SDK installed, and for whatever reason the project I was trying to use needed .NET 6.0 SDK.

I had this same issue, and it turned out the resolution for me was none of the above for me. I was running the VS preview version with an older version of VS. I removed the Preview VS and then had to remove each of the environment variables by hand (i.e ANDRIOD_HOME, and .Net Maui vars, etc) and was back in business. Hope this helps someone out there who has installed VS Preview only to break the dev build environment.

Had the same issue after I updated (snip) all VS installations on my windows machine a while ago. A restart of my PC resolved the issue.

The issue was occuring for me only when I tried to build the project with dotnet build using VS2022 . MsBuild on the same project was working fine.

What I did was:

restore the .net core runtime sdk - I was using 3.1 at the time.
Add both sdk paths in both Path vars, for the user and system, in that order:

Delete the MSBuildSDKsPath

P.s. I had this error while trying to run the coverlet coverage analysis

I got the same issue when I tried to install x64 .Net Core SDK installer. Even the following dotnet --info command shows me that no SDK is found.

So, try to install x86 .Net Core SDK installer. That can help you.

Maybe you encountered the error after installing .NET core SDK 3.0. You have to check the environment variable MSBuildSDKsPath after every install of a new SDK. It must target the SDK you use to create your project. I use VS2017 with Windows 10.

For 2.2 SDK:

C:\Program Files\dotnet\sdk\2.2.104\Sdks

For 3.0 preview :

C:\Program Files\dotnet\sdk\3.0.100-preview3-010431\Sdks

I started getting this error after installing Visual Studio 2022 in Windows 10, when I opened up my solution. The solution contains a mix of .NET Framework 4.8 and .NET Standard 2.0 projects, and the error was on the .NET Standard 2.0 projects. I had previously Visual Studio 2019 and 2019 Build Tools installed.

The problem was that I had both x86 and x64 of dotnet installed, and both was in my systems PATH environment variable:

C:\Program Files (x86)\dotnet
C:\Program Files\dotnet

I did the following steps to fix this error:

Uninstalled VS2019
Uninstalled VS2019 Build Tools
Removed the x86 path from the environment variable
Removed the folder "C:\Program Files (x86)\dotnet" from my computer
Restarted VS2022

I think that the important part was to remove x86 from the environment variable. The other steps was just to "clean up".

For me updating Visual Studio Build Tools resulted in the 'SDK not found' error.

The solution: run Visual Studio Installer, modify the Visual Studio (Build Tools) installation, and make sure the following workload is selected:

If you have previously worked with C# and it somehow stopped working:

For me updating to the latest version (probably of the build tools) with the "Visual Studio Installer" solved the problem.

You were probably missing some components when you installed the VS tools

Download and run Build Tools for Visual Studio 2019. (On the VS download page, go to Tools for Visual Studio 2019 and then click download Build Tools for Visual Studio 2019)
Select Modify on Visual Studio Build Tools 2019 or your instance.
Select tab Individual components and check .NET Core SDK component

I got this issue in Mac OS and while using docker container and Azure this occurs because docker bash overrides MSBuildSDKsPath so don't change any code just quit and restart your IDE (visual studio Mac) and run it again

To anyone that, like me, run into this issue on Linux and found this thread:

This problem occurs, because your .bashrc config overrides MSBuildSDKsPath environment variable with outdated value (most likely it's a leftover after dotnet package update). To solve this:

Edit ~/.bashrc
Remove the line with MSBuildSDKsPath variable initialization, e.g.

export MSBuildSDKsPath="/opt/dotnet/sdk/2.2.108/Sdks/"

for me the solution was to set the sdk version in the global.json file:

and specify the correct version which exists in the C:\Program Files\dotnet\sdk folder. The VS installer uninstalled the previous version of .NET Core 3.0.100 and installed new one 3.1.100 so I had to change it from:

{  "sdk": {    "version": "3.0.100"  }}

{  "sdk": {    "version": "3.1.100"  }}

I had the same problem and found solution here: https://github.com/aspnet/AspNetCore/issues/3624

Solution is to just have x64 or x86 version of sdk/runtime/hosting. If you have both and if you use for example x86 version of dotnet.exe it won't see x64 versions of SDK installed.

Problem usually occures when you install hosting bundle because it includes both x86 and x64. Just uninstall one you don't use.

I encountered this error after playing around with .Net Core 2.0 installation and seemingly messing it up. I would get this same error for dotnet restore, dotnet build or dotnet msbuild. Essentially, anything involving .Net Core and msbuild.

The error occurred because the MSBuildSDKsPath environment variable was still pointing to the old .Net Core 1.1 SDK.

To fix the problem, I manually set the MSBuildSDKsPath environment variable to point to 2.0.0's SDK path, which, for me with x64, this was at: C:\Program Files\dotnet\sdk\2.0.0\Sdks.

Basically, if you have Sdk="Microsoft.NET.Sdk" in your .csproj, then a folder with the same name should exist at your MSBuildSDKsPath location.
