  • Windows 10, version 1903 removed the redundant metadata files from the Syswow64 folder.  Visual Studio 2015 on 64 bit systems is using those files to load the designer.  Visual Studio 2017 and Visual Studio 2019 do not have this issue.

    To work around this issue, you can take the following steps:

    1) Launch an administrative command prompt
    2) Type in the following command: 

    if NOT exist C:\Windows\Syswow64\WinMetadata xcopy C:\Windows\System32\WinMetadata\*.*  C:\Windows\Syswow64\WinMetadata /S /I

    This will work around this issue by copying the system metadata from the System32 directory to the Syswow64 directory.
