4 posts · May 2014 – Apr 2015

What this trail covers

Visual Studio's .NET Edit and Continue (EnC) functionality has been enhanced to support lambda expressions, remote debugging, debugging on Windows Phone 10 emulators, and attaching to processes. This builds upon previous improvements and addresses limitations in earlier versions, aiming to streamline the debugging experience for .NET developers. This post details improvements in Visual Studio 2015 CTP 6, including support for adding methods, fields, constructors, properties, events, indexers, and lambda expressions in the Watch window.

All Microsoft trails

Apr 2015.NET EnC support for Lambdas and other improvements in Visual Studio 2015This post announces further Edit and Continue (EnC) improvements in Visual Studio 2015 RC, specifically adding support for creating and editing lambda expressions, enabling EnC while remote debugging, supporting EnC on Windows Phone 10 emulators, and introducing EnC on attach via the COMPLUS_FORCEENC=1 environment variable. It also details limitations, such as the inability to use EnC with ASP.NET 5 applications at this stage, restrictions on attaching and detaching, and the inability to use EnC when debugging inside of IIS in the RC.
Feb 2015EnC Improvements for .NET Debugging in Visual Studio 2015This post announces improvements to .NET Edit and Continue (EnC) in Visual Studio 2015 CTP 6. Key enhancements include support for adding various code elements (methods, fields, types), modifying constructor bodies and initializers, and working with async/await, dynamic objects, iterators, and C# 6.0/VB 14 features. It also introduces support for reordering type members and type parameter constraints, and refactoring via Ctrl + .. The post also highlights the addition of 'Make Object ID' support for lambda expressions.
Nov 2014Support for debugging lambda expressions with Visual Studio 2015This post announces the addition of support for evaluating lambda expressions within the Visual Studio debugger's Watch window. Previously, this was a limitation that prevented debugging code using LINQ or other lambda constructs directly in the debugger. The post provides a code example and notes that lambda expressions requiring native functions (e.g., LINQ-to-SQL) are not yet supported.
May 2014.NET Edit and Continue SurveyThis post reports on the results of a survey regarding the importance of .NET Edit and Continue. It highlights that the inability to modify or add LINQ queries or lambda expressions is the most frequently reported limitation. The post announces that work is underway to address this in the next release of Visual Studio, involving the Visual Studio debugger, .NET Runtime, and Managed Languages teams.
