Implement RFC0005: Enable Remote Debug Support

[ryanmoran]

RFC
Exploration

Describe the Enhancement

The .NET Core buildpack should enable remote debugging of applications in a manner that conforms to Project RFC0037. To accomplish this, the buildpack will need to install the Visual Studio Debugger into the application run image. The debugger can attach to a running dotnet process and be bound to a client-side debugger via STDIN across a connection invoked via docker exec or kubectl exec.

Motivation

Remote debugging is a useful practice for understanding complex program logic and interactions in remote environments including production. Providing this feature for .NET Core developers will bring this buildpack into alignment with the types of features we already provide for developers in other language families like Java.

Steps

• Implement RFC0005: Create buildpack for vsdbg installation #745
• Implement RFC0005: Compile applications for remote debugging dotnet-publish#337
• Implement RFC0005: Enable support for remote debugging with vsdbg dotnet-execute#329
• Implement RFC0005: Add vsdbg buildpack to each order group #746
• Add How To for Enabling Remote Debugging paketo-website#562
