I had the same problem with an ASP.net Core 2.0 project after I've installed the DotNetCore.2.0.5-WindowsHosting Framework on my development machine.

After this I've reinstalled the dotnet-sdk-2.1.200-win-x64 package and everything worked fine.

Same issue...took me a while to figure out. Since I was working on an ASP.NET Core project that targeted .NET Core 1.1, I thought I still needed the .NET Core 1.1 SDK installed. Since I had .NET Core SDK 2.1 installed too there was some sort of conflict and I couldn't open the project file. After uninstalling .NET Core 1.1 I was then able to open my project.
