 ### Fixed
 - Updated `HttpContext.Current` analyzer to more correctly identify uses of `HttpContext.Current` that need replaced [#628](https://github.com/dotnet/upgrade-assistant/pull/628).
+- The Upgrade Assistant analzyer package no longer adds a WebTypeReplacements.typemap file to projects it's added to (more precisely, the file is present and available for analyzers to use but isn't visible in the solution explorer anymore) [#632](https://github.com/dotnet/upgrade-assistant/pull/632).
