Today we’re very happy to announce that the second preview of the next minor release of ASP.NET Core and .NET Core is now available for you to try out. This second preview includes many refinements based on feedback we received from the first preview we released back in February. 

These are the customer-reported issues addressed in this release:
- The debugger cannot continue running the process. Operation not supported. Unknown error: 0x9233000b.
- Recent Projects and Solutions not populated once executed.
- Full build every time with 15.5.
- Wrong IntelliSense errors are still shown on VS 15.5.2 for Visual Basic projects.
- VS2017 15.5.2 Unresolved references when "Allow parallel project initialization" is enabled.
- Upgrading to 15.5.2: cannot launch nor repair VS.
- VS2017 Installation issue.
- Unable to install because of BSoD.

A common question from customers is how to have an RPC (as in .NET Remoting and Windows Communication Foundation) experience on .NET Core. We are contributing to the gRPC (grpc.io) project to ensure gRPC will have first-class support for .NET developers.
