Error restoring watch when trying WatchMultipleProjects in samples

[FlukeFan]

I am trying to watch multiple projects. An example repo is here: https://github.com/FlukeFan/WatchCustomProject

When I try to run dotnet watch ...

I get the error No executable found matching command "dotnet-watch"

I added the following to my .proj file:
<ItemGroup>
<DotNetCliToolReference Include="Microsoft.DotNet.Watcher.Tools" Version="2.0.0" />
</ItemGroup>

Then I ran dotnet restore ...

I get the error error MSB4057: The target "Restore" does not exist in the project

I added the following line to my .proj file (taken from the WatchMultupleProjects sample):
<Import Project="$(MSBuildToolsPath)\Microsoft.Common.targets"/>

Then I ran dotnet restore ...

Now I get the more cryptic error:
C:\Program Files\dotnet\sdk\2.0.2\NuGet.targets(102,5): error : Value cannot be null.\r [C:\work\scratch\dotnet\WatchCustomProject\Build\Build.proj] C:\Program Files\dotnet\sdk\2.0.2\NuGet.targets(102,5): error : Parameter name: key [C:\work\scratch\dotnet\WatchCustomProject\Build\Build.proj]

I tried cloning the DotNetTools repo, and ran dotnet restore watch.proj in the WatchMultipleProjects folder and got the same error.

Is this a bug? Or am I missing something?

I updated the samples to work with the 2.0.0 SDK. NuGet made some changes to their internal targets that were causing the "Valeu cannot be null" error. 1cc289c

Give it a shot and let me know if it doesn't work. We can re-open if it doesn't.

Side note: this sample is sort of a hack until we can implement #319

Thanks, that seems to work perfectly.

IMHO, the ability to watch arbitrary targets in a custom msbuild file is a more flexible solution than #319.

(i.e., I prefer the custom build file, rather than a long (potentially, very long) command line of projects to watch)

Thanks again.
