@anorborg : As a workaround, you should also be able to make it work by setting the MSBuildSDKsPath environment variable to /usr/local/share/dotnet/sdk/2.0.2/Sdks.

Sorry I need to update my issue report.
The OmniSharp log above was produced with an environment set to an obvious wrong location.
When setting 

MSBuildSDKsPath=C:\Program Files\dotnet\sdk\1.0.1\Sdks

it is working.

BUT with out any MSBuildSDKsPath being set it defaults to the non existing path

D:\User\cja\.vscode\extensions\ms-vscode.csharp-1.13.0\.omnisharp\msbuild\15.0\Bin\Sdks

and the mentioned error occurs.

So, it seems to be required to explicitly set the environment MSBuildSDKsPath (correctly) in order to get OmniSharp to run with version 1.13.0

This was not necessary with previous versions.

Thanks for the detailed information. Could you check D:\User\cja\.vscode\extensions\ms-vscode.csharp-1.13.0\.omnisharp\omnisharp\msbuild\15.0\Bin\ and let me know if there is an SdkResolvers folder there?

DustinCampbell picture DustinCampbell on 9 Nov 2017

Yes, I can confirm that there is a SdkResolvers folder (containing a Microsoft.DotNet.MSBuildSdkResolver...).

cjaeckel picture cjaeckel on 9 Nov 2017

Thanks! Without MSBuildSDKsPath set, could you set COREHOST_TRACE=1 and load your project is VS Code? This should add spew a bit of diagnostics in your OmniSharp Log when the SdkResolver tries to locate your SDK.

DustinCampbell picture DustinCampbell on 9 Nov 2017

Okay, I added COREHOST_TRACE=1 and removed MSBuildSDKsPath.
When now loading the project the probing for the SDK path seems to happen after the actual project load:

When now loading the project the probing for the SDK path seems to happen after the actual project load.

I wish it were as simple as that, but I'm not sure. @nguerrera, do you know if this would even be possible?

FYI, I manually installed 1.12.1 and it worked again

From the looks of that log sequence, it seems like something evaluated the project without the resolver, then something else did it with the resolver. Are there two msbuilds involved somehow and one of them does not have the resolver?

It does look that way, but OmniSharp does not run MSBuild in parallel and only one MSBuild is ever used. In the OmniSharp Log above, it is using the MSBuild that is included with OmniSharp, which includes it's own copy of the SdkResolvers.

Ah! CLI versions less than 1.0.4 had a bug where SDK to SDK imports did not use the right mechanism. This means they were fundametally broken when we introduced SDK resolution. The resolver will reject anything lower than 1.0.4.

We issue an error message for this case:

But msbuild isn't surfacing it to the user. I thought this was due to the legacy Sdks directory, but here I see it happening without that present. https://github.com/dotnet/cli/issues/6887 tracks getting this error to surface correctly.

Thanks @nguerrera! @cjaeckel : Have you considered updating your .NET Core SDK to a newer version? It sounds like that would address the problem: https://www.microsoft.com/net/download/windows. .NET Core SDK 1.0.4 is still available here, though a newer version might serve you better.

I've just pushed a new release that should help address this issue: 1.13.1. We'll be pushing this to marketplace sometime today. However, if you want to try it out, you can follow the instructions here to install it.

Looks like even now, I needed to create launch code with the environment variable MSBuildSDKsPath set to the proper location c:\Program Files\dotnet\sdk\2.1.302\Sdks in my case. Is this normal at this point? Or did I improperly setup dotnet so it didn't alter my path?

omartin2010 picture omartin2010 on 11 Oct 2018

@omartin2010 Is dotnet not on your PATH? How did you install it?

nguerrera picture nguerrera on 11 Oct 2018

dotnet is on my path (specifically, c:\Program Files\dotnet\ is, but c:\Program Files\dotnet\sdk\2.1.302\SDKs wasn't. Is this expected?

Is this expected?

Yes, that is normal.

nguerrera picture nguerrera on 12 Oct 2018

I guess it’s expected from Code’s point of view, but do you know if it Iis expected that I need to _manually add_ the dotnet core’s SDK subdirectory to the path to get this to work for a project that’s built using dotnet core that is in the path? If so, that doesn’t sound right as it gets people wasting time trying to understand why intellisense doesn’t work for these libraries when it should… if the path is set properly. Unless it’s my install of the SDK that had gone wrong. Oh well..

I would like to add my two cents to this:

  • I run OpenSUSE Tumbleweed
  • I've never installed Mono
  • A long time ago I used to manually download and install .NET Core
  • Everything worked fine
  • I transitioned to getting my packages from https://packages.microsoft.com/opensuse/42.2/prod
  • Everything worked fine
  • In Summer 2018 I transitioned to <TargetFramework>netcoreapp2.1</TargetFramework>
  • My work computer worked fine, my computer at home started having SDK resolution problems.
  • Updated work machine to 
.NET Core SDK (reflecting any global.json):
 Version:   2.1.302
 Commit:    9048955601

Runtime Environment:
 OS Name:     opensuse-tumbleweed
 OS Version:  20181015
 OS Platform: Linux
 RID:         linux-x64
 Base Path:   /usr/share/dotnet/sdk/2.1.302/

Host (useful for support):
  Version: 2.1.2
  Commit:  811c3ce6c0

.NET Core SDKs installed:
  2.1.4 [/usr/share/dotnet/sdk]
  2.1.302 [/usr/share/dotnet/sdk]

.NET Core runtimes installed:
  Microsoft.AspNetCore.All 2.1.2 [/usr/share/dotnet/shared/Microsoft.AspNetCore.All]
  Microsoft.AspNetCore.App 2.1.2 [/usr/share/dotnet/shared/Microsoft.AspNetCore.App]
  Microsoft.NETCore.App 2.0.5 [/usr/share/dotnet/shared/Microsoft.NETCore.App]
  Microsoft.NETCore.App 2.0.9 [/usr/share/dotnet/shared/Microsoft.NETCore.App]
  Microsoft.NETCore.App 2.1.2 [/usr/share/dotnet/shared/Microsoft.NETCore.App]
  • Now both machines had SDK resolutions.

After picking through the GIT issues related to

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

To track down my problem I created a brand new project:

dotnet new console
COREHOST_TRACE=1 code .

This was enough to reproduce the problem and my log showed how Omnisharp resolved its paths.

...
MSBuildToolsDirectory32: ~/.vscode/extensions/ms-vscode.csharp-1.16.2/.omnisharp/1.32.7-beta.8/omnisharp/msbuild/15.0/Bin
MSBuildToolsDirectory64: ~/.vscode/extensions/ms-vscode.csharp-1.16.2/.omnisharp/1.32.7-beta.8/omnisharp/msbuild/15.0/Bin
MSBuildSDKsPath: ~/.vscode/extensions/ms-vscode.csharp-1.16.2/.omnisharp/1.32.7-beta.8/omnisharp/msbuild/15.0/Bin/Sdks
CurrentMSBuildConfigurationFile: ~/.vscode/extensions/ms-vscode.csharp-1.16.2/.omnisharp/1.32.7-beta.8/omnisharp/msbuild/15.0/Bin/MSBuild.dll.config
CurrentMSBuildExePath: ~/.vscode/extensions/ms-vscode.csharp-1.16.2/.omnisharp/1.32.7-beta.8/omnisharp/msbuild/15.0/Bin/MSBuild.dll
CurrentMSBuildToolsDirectory: ~/.vscode/extensions/ms-vscode.csharp-1.16.2/.omnisharp/1.32.7-beta.8/omnisharp/msbuild/15.0/Bin
VisualStudioInstallRootDirectory: 
MSBuildExtensionsPath: ~/.vscode/extensions/ms-vscode.csharp-1.16.2/.omnisharp/1.32.7-beta.8/omnisharp/msbuild/15.0/Bin
...

Of course there is no Microsoft.NET.Sdk in the built in $(MSBuildSDKsPath) hence my error.

The SDK 'Microsoft.NET.Sdk' specified could not be found.  ~/Work/se.client/se.client.csproj`

Somehow I need to get Omnisharp to resolve to /usr/share/dotnet/sdk instead. My problem was a combination of a dead soft link and my PATH variable.

@host:~/Work/se.client$ echo $PATH
~/bin:/usr/local/bin:/usr/bin:/bin:/~/.dotnet/tools

@host:~/Work/se.client$ which dotnet
/usr/bin/dotnet

@host:~/Work/se.client$ ls
lrwxrwxrwx 1 root root 18 Oct 26 07:56 dotnet -> /opt/dotnet/dotnet

The link /usr/local/bin/dotnet was invalid; it is a remnant of my old manual installation, i.e. /opt/dotnet no longer exists. Deleting the dead link fixed my problem and everything works again.

I surmise the following:

  • Omnisharp uses its own implementation to search PATH
  • It does not validate links
  • It errors out trying to run an invalid dotnet and falls back to a different
    resolution.

To recreate my error on a working system:

mkdir -p ~/snf/bin
cd ~/snf/bin
ln -sf `which dotnet`_bad dotnet
mkdir -p ~/snf/test
cd ~/snf/test
dotnet new console
export PATH=~/snf/bin:${PATH}
COREHOST_TRACE=1 code .

@ChickJ Thanks for sharing--you're right that we could improve how we handle unresolvable paths. I've filed https://github.com/OmniSharp/omnisharp-vscode/issues/2629 to track this.

I've got the same issue: 'Microsoft.NET.Sdk' specified could not be found. Macosx, OmniSharp 1.18.0-beta6.
Fixed it by setting up MSBuildSDKsPath=/usr/local/share/dotnet/sdk/3.0.100-preview-010184/Sdks
I assume it is not expected behaviour.

This issue doesn't seem specific to VSCode integration and can happen woth OmniSharp roslyn in general.
See https://github.com/OmniSharp/omnisharp-roslyn/issues/1416#issuecomment-477284941

So I ran into this issue today as well. But I fixed it.

I'm running:

  • Windows 10 v1803
  • .NET Core v2.2
  • VSCode v1.33.1

I think what caused it was my process:

  1. Installed .Net core (no previous version of .NET was installed and I did not restart laptop).
  2. Next do the Tutorial https://docs.microsoft.com/en-us/dotnet/core/tutorials/with-visual-studio-code.
  3. Get an error:
    Microsoft.Build.Exceptions.InvalidProjectFileException: The SDK 'Microsoft.NET.Sdk' specified could not be found. C:\Path\to\your\project\file\here.csproj

To possibly resolve:

  1. Restart computer.
  2. Open Visual Studio Code and reload/re-install the extension.

Could it really be possible that a simple restart after installing core and before installing the extension to allow environment variables to exist/update is the solution?
