[.NET Core] Unable to load ‘\.\hostfxr.dll’. This might be caused by a bitness mismatch between IIS application pool and published application.
After I deploy application to iis, I got the error message “HTTP Error 500.32 – ANCM Failed to Load dll“. then I open event viewer, I found the error message “Unable to load ‘.\hostfxr.dll’. This might be caused by a bitness mismatch between IIS application pool and published application“.
Step 1. Open IIS manager > Application Pool > Select App pool > Advanced Settings
Step 2. Update “Enable 32 bits applications” from false to true > Click OK
Step 3. Open the site, the issue has been resolved.
