You Might Not Need to Upgrade: The Case for Staying Put

Show Notes

Hey everyone, and welcome back to The Modern .NET Show; the premier .NET podcast, focusing entirely on the knowledge, tools, and frameworks that all .NET developers should have in their toolbox. I'm your host Jamie Taylor, bringing you conversations with the brightest minds in the .NET ecosystem.

Today's episode is another one without a guest; it's just me again. This is part two of the series I started at the top of the season, Bridging the Gap, and if you're wondering where part two got to, we had a standard episode in between. That'll keep happening. The series numbers and the season numbers are going to drift apart, and I'll say which part we're on every time so nobody has to do arithmetic..

Anyway, without further ado, let's sit back, open up a terminal, type in `dotnet new podcast` and we'll dive into the core of Modern .NET.
