vscode-csharp: The SDK 'Microsoft.NET.Sdk' specified could not be found

Issue Description

Fresh installation of .NET Core 3, VSCode, and the C# extension fails to open apps created by dotnet new console -o test-app on Fedora 29. Some of the related issues have workarounds, but they only work on Windows.

Steps to Reproduce

Install .NET Core 3 snap:

sudo snap install dotnet-sdk --beta --classic
sudo snap alias dotnet-sdk.dotnet dotnet

Install VSCode:

sudo rpm --import https://packages.microsoft.com/keys/microsoft.asc
sudo sh -c 'echo -e "[code]\nname=Visual Studio Code\nbaseurl=https://packages.microsoft.com/yumrepos/vscode\nenabled=1\ngpgcheck=1\ngpgkey=https://packages.microsoft.com/keys/microsoft.asc" > /etc/yum.repos.d/vscode.repo'
dnf check-update
sudo dnf install code

Install the C# extension in VSCode
Create a new project:
```
dotnet new console -o test-app
```
Open the test-app folder in VSCode. It will show an error.

Expected Behavior

The project opens successfully, I am able to debug the program.

Actual Behavior

Small window pops up with an error. I have to manually configure the debug configurations.

For now, you should be able to workaround things by forcing omnisharp to use the legacy resolver that just shells out to dontet --info. You can do this by creating ~/.omnisharp/omnisharp.json with this content:

{
   "MSBuild": {
       "UseLegacySdkResolver": true
   }
}

I don’t think that failure to load a satellite assembly is the actual issue. Notice it couldn’t find Microsoft.Build.resources.dll either. I believe the problem is that dotnet on PATH from snap alias is not a symlink to the real dotnet executable that is next to the sdk. The non-legacy resolver expects that to be the case.
