Legacy code isn't always well-commented. For .NET libraries or for NuGet packages enabled for SourceLink, you can also step into source code, set breakpoints, and use all the debuggers features. Most of the differences are in places where the information in the original source code isn't needed at runtime. It seems to take it half a minute to generate several files from a large assembly (think PresentationFramework I know the sources are available anyway, its just a good example), compared to a few seconds for the entire assembly by using ILSpy directly. Check the Output window at the bottom to see where the DLL file was created. Create better controls, WebParts, and features by seeing how they work, and how the code runs. wikiHow, Inc. is the copyright holder of this image under U.S. and international copyright laws. Being able to look into the decompiled IL allows me to work towards an immediate resolution, and one thats broadly appropriate. In order to accomplish this we are partnering with ILSpy, a popular open source project, which provides first class, cross platform symbol generation and decompliation. .NET Reflector saves time and simplifies development by letting you see and debug into the source of all the .NET code you work with. {"smallUrl":"https:\/\/www.wikihow.com\/images\/thumb\/6\/66\/Edit-DLL-Files-in-Visual-Studio-Step-2.jpg\/v4-460px-Edit-DLL-Files-in-Visual-Studio-Step-2.jpg","bigUrl":"\/images\/thumb\/6\/66\/Edit-DLL-Files-in-Visual-Studio-Step-2.jpg\/aid13105522-v4-728px-Edit-DLL-Files-in-Visual-Studio-Step-2.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"
