Coder - Speaker - Microsoft MVP - Scuba Instructor

I’m a geek and I love sharing about the technologies that excite me. I do this through speaking at conferences, user groups, and other local events, organizing the Kansas City .NET User Group, providing technical training, writing on my blog, and sometimes on other outlets like Twitter, GitHub, Instagram, and YouTube. I’m honored to have my community involvement recognized by Microsoft with their MVP Award.

I don’t just geek out over software development. I also teach SCUBA diving as a PADI Open Water Scuba Instructor. If you are interested in discovering the underwater world through SCUBA I’d love to talk. You can learn more at Duane & Lisa's Diving Adventures.

Basic Authentication with TFS Package Server

I recently encountered some authentication issues connecting my Mac to the package service hosted on a client’s on-prem TFS server. The server is on a Windows domain and normally I access TFS from a windows VM that is joined to the domain. However, I’ve recently found myself on my Mac more often while working on one of thier Xamarin mobile apps. This is when I began having problems. The Poblem The client has a couple NuGet packages hosted on the TFS server using the Package Management extension, and whenever I tried to do a NuGet restore I would run into authentication errors.
