Can't build as x64?

[shilixiang]

Hi,
This new tooling looks fantastic, it makes managing Azure Functions much easier.
But I got an issue when trying to reference a x64 Nuget package.
If I set Solution Platform to Any CPU, then the dll in Nuget package can't be loaded.
If I set Solution Platform to x64, then Azure Functions solution won't build.

With the following error:
Could not load file or assembly 'file:///c:\Users\Documents\Visual Studio 2017\Projects\FunctionApp1\FunctionApp1\bin\x64\Debug\net461\FunctionApp1.dll' or one of its dependencies. An attempt was made to load a program with an incorrect format. FunctionApp1 C:\Users\lishi.nuget\packages\microsoft.net.sdk.functions\1.0.0-alpha3\build\netstandard1.0\Microsoft.NET.Sdk.Functions.targets

It seems this tooling doesn't support x64. But x64 is already supported on Azure Functions Portal according to this post: https://github.com/projectkudu/AzureFunctionsPortal/issues/894

Thanks,
Kevin

This is because the CLI is built as 32-bit. We have an item to produce an x64 build, see Azure/azure-functions-core-tools#117.

Closing this issue as it's tracked elsewhere.
