Visual Studio 2017 – 7 lesser known debugging tips

2 point on “Data Breakpoints” is really useful. Sometimes we just want to debug a single instance of a type. The ability to assign an ID to an object (e.g. $1) we want to trace and set this=="$1" is just brilliant!

VS2017 has spent a lot of effort trying to make the debugger more developer friendly for multi-threaded application. Appreciate your effort, Microsoft 🙂

Windows Authentication EF Impersonation


Your EF connection string is going to need to be set up for using a trusted connection.

You won’t need to set up Impersonation in your web.config, but you do need to be using Windows Authentication.

Then just do this:

using (((WindowsIdentity)HttpContext.Current.User.Identity).Impersonate())
using (var dbContext = new MyEntityFrameworkContainer())

Any code inside the curly braces of the using statements will run as the authenticated user.
