VS2017 Build Error The process cannot access the file

Hello,

I am running VS2017 version 15.3.3.  I just updated it yesterday in an attempt to resolve this issue.  When I attempt to build a C# WPF project for a second time, I get a build error telling me the .EXE file is in use by another process.  Closing the solution and reopening allows me to build the project.  This is very annoying and unproductive.  

This only occurs after I edit and save the MainWindow.xaml file.  I have also tried closing the xaml file before attempting the second build without any success.
