It built now! I think the issue was I had web.config in the <Content> tag, and it was overlapping with the one on Microsoft.NET.Sdk.Web.

Thanks a lot!

If you know you have the 1.1 SDK from https://www.microsoft.com/net/download/core and you have 1.0.0-preview3-004056 tooling from https://github.com/dotnet/core/blob/master/release-notes/preview3-download.md, check out the notes from @vijayrkn in https://github.com/aspnet/IISIntegration/pull/299. He got me patched up. 🚑
