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

[MiaomiaoHuangfu]

Create an ASP .NET Core Web Application (.NET Core) project prompting a window: "The SDK 'Microsoft.NET.Sdk.Web' specified could not be found.".

Test on d15prerel.26526.3002
OS: Windows 10 X64

[mlorbetske]

This should be fixed in later builds of d15prerel. @MiaomiaoHuangfu please file these in TFS or on https://github.com/aspnet/websdk or https://github.com/dotnet/templating rather than on this repo. We're moving toward this repo being used for feature requests/discussions & trying to move away from tracking product issues here (especially for internal builds)

[robertmclaws]

So, it's great that the issue is fixed in later builds, but if I'm outside Microsoft and don't have access to newer builds, how do I fix it?

Thanks!

[davidfowl]

This issue was reported on an internal build to begin with. If you're seeing the issue it might be something completely different, or it might have been a bug in the preview that you can't work around.

What exactly are you seeing?

[robertmclaws]

The exact same error message and dialog on VS2017.3 Preview 3. I had a .NET Core web project open and was working fine, I restarted my machine, and then it was broken. I tried repairing the .NET Core SDK, uninstalling and reinstalling, neither of which had any effect. I needed to get back to work, so I'm trying a VS repair and seeing if that fixes it.

[mlorbetske]

Could you check your PATH environment variable to see if there are entries for a dotnet directory under both Program Files and Program Files (x86) please? If there are two entries, could you move the Program Files one to be before the Program Files (x86) one, restart Visual Studio and see if that helps please?

[robertmclaws]

Hmm, there are actually NO PATH entries for dotnet anymore, even after repairing both the SDK and VS2017.3.

What are they supposed to be?

[robertmclaws]

OK, it's supposed to be C:\Program Files\dotnet\ (as found on another machine). Adding it back to the PATH and restarting VS solved the problem.

[natemcmaster]

We got another report of this issue in latest preview builds of VS. https://github.com/aspnet/Home/issues/2113. For some reason, this error only applies to projects with Microsoft.NET.Sdk.Web. Other non-web Microsoft.NET.Sdk projects from the same solution load fine.

[aKabirKhan]

Any update on this, we are stuck since code analysis is only working after 2015.3 preview 2 and installing preview 6 breaks the sln with error mentioned above.

[kspearrin]

This just happened to me. .NET Core 2.0 installed under X64 (Program File\dotnet). My path was set to Program Files (x86)\dotnet. Changing path to Program File\dotnet solved the problem.

[aKabirKhan]

I tried installing the .net core 2.0 again and check the env var for both user and system they are accurate(c:Program File\dotnet). But still cannot open the project. Below is my project that fail to load

I experienced this issue with VS2017 Preview 3 and an Azure Functions project (attempting to create an Azure Function from a class library). None of the path alterations mattered, nor did a VS2017 "repair" - but removing the sdk property entirely from a several-directories-upstream global.json file (universal for a very large codebase) resolved a similar error (project wouldn't load, error message was 'unable to find Microsoft.Net.SDK.Publish').

"My path was set to Program Files (x86)\dotnet. Changing path to Program File\dotnet solved the problem." - How check my current path and change it to another one ?

[sandykulk]

Any update on this issue. I have set the path to "c:Program File\dotnet" but still cannot open the project.

[ghost]

I figure it out.

1. Remove all .net core frameworks from your computer.
2. Install .net core 2.0
3. add global.json to your project and point sdk 2.0.0

{
"projects": [],
"sdk": { "version": "2.0.0" }
}

Additional info

Visual Studio 2017 Community Update 3 -> Version 15.3.3
In your dotnet core web application .csproj leave: Microsoft.NET.Sdk.Web !

You can check info by typing dotnet --info in CMD

[brijmcq]

@letsgoforaride guide works well. In my case, I didn't need to remove all previous .net core frameworks, I just did the step 3, just updating the sdk to 2.0.0 in global.json and voila

[barrytang]

Adding @livarcocc who owns the .NET Core CLI as FYI.

[cbassigit]

Step 3 from @letsgoforaride guide work for me as well. There was no need to remove previous frameworks. I had to create global.json file but it worked great (1st .net core project for me).

[brijmcq]

There is actually a good guide on this https://docs.microsoft.com/en-us/aspnet/core/migration/1x-to-2x/, but I think they should include what kind of errors you will be getting if you don't follow the migration guide.

[donsartain]

I'm having the same problem, without VS 2017 installed.

OmniSharp warning: The SDK 'Microsoft.NET.Sdk.Web' specified could not be found.

global.json

{ "projects":[], "sdk": { "version": "2.0.0" } }

[manish-jain-1]

Still happening on VS2017 15.3.5 + core 2.0. tried all above solutions.

[lalalaring]

Still happening on VS2017 15.4.0 + core 2.0. tried all above solutions.

[CDuke]

I had the same problem on VS2017 15.4.0 + core 2.0.
I'm repair .NET Core SDK 2.0.2 and restart Visual Studio. After that problem gone.

[kikomi]

Had this problem with VS2017 15.4.0 + .NET Core 2.0
Solved with installation of proper version of .NET Core SDK i.e. version of .NET Core SDK (x86/x64) has to much version of Visual Studio.

[lalalaring]

VS2017 15.4.0 + .NET Core 2.0,Solved with change dotnet path from system path to user path

[frank-lores]

Changing the PATH Environment variable from C:\Program Files(x86)\dotnet to C:\Program Files\dotnet fixed the problem.

[YuriyZaletskyy]

Neither adding global.json, nor adding for user path: C:\Program Files\dotnet\ didn't solve the problem for me.

[Alex61NN5]

Still not working, none of the above solved for me

Could you PLEASE explain us how to solve this old issue? In my case, upgrading the SDK version is not an option.
