Content Manager Does Not Open - VS 2017

My Content Manager no longer opens when I click on the Content.mgcb file. It opens the file itself instead. Using Visual Studio 2017 and the latest dev branch of MonoGame. It has worked without issue for months now. I haven’t had a Windows Update in weeks (I’ve successfully used it after the last Windows Update)… Anyone else with VS2017 having issues?

Never mind. Apparently, the MonoGame Pipeline Tool was no longer set as the default program to open the file with. Not sure how that got changed, but just had to set it back to default…
