Enables Windows Explorer file preview for email files (.msg, .eml), without having Outlook installed.
For HTML email preview, Renderer is used instead of WebBrowser (seems quite buggy). If problems occur, discard Setup.msi and test with "Server Manager"; install both x86 and x64 (same DLL). Most times, however, one architecture seems to be enough.
https://github.com/dwmkerr/sharpshell/wiki/Debugging-&-Diagnostics Log mode has to be configured via srm.exe to be able to see the logs, and must be run in Server Manager via Test Shell.
See Codebase parameter(s).
For a successful install and registering, the DLLs must use "strong names", i.e. be signed. Therefore, an additional NuGet package is needed which signs MimeKit, HTML Renderer etc. after installation: StrongNameSigner. Note this can cause issues with other NuGet packages (System.Security error etc.); in this case, temporarily uninstall the Signer.
