Unable to find package when attempting to run benchmarks

[drieseng]

When I attempt to run the benchmarks in master I get the following errors:

// ***** BenchmarkRunner: Start   *****

I followed the Building from source instructions. Building the sources works just fine (using both VS and dotnet build).

What am I missing?

[drieseng]

@JamesNK Any idea?

[rynowak]

Did you run build.cmd first? Those scripts acquire the required version of the runtime - which include Microsoft.NETCore.App

[drieseng]

Yes, I ran build.cmd /t:restore as mentioned on Building from source.

It works just fine on the release/2.2 branch. This may be because that one uses the .NET Core 2.2 toolchain, while master uses .NET Core 3.0.

I encountered the same error on the 3.0 branch a few weeks ago. I think I resolved it by changing the environment path to dotnet install folders. I'm not completely sure because I was trying to fix another problem and it suddenly resolved itself.

@drieseng, did you get a chance to try @JamesNK's suggestion:
