We use onedrive/sharepoint for our document storage and there is a ability to open files in the desktop app. You use an extension on the url which is built into most browsers for your javascript so I prebuild the url with the correct extension below. It seems that there might be one for adobe as onedrive has this functionality but I think I am doing this wrong as it errors out in my javascript when it goes to open the new window via the built url:

        [HttpPost]
    [ValidateAntiFeryToken]
    public async Task<ActionResult> SharedLinkData([FromForm] string FilePath)
    {

        var fullPath = Path.Combine(fileDirectory, FilePath);
        var SharedLinkResponse = await oneDrive.DriveItemLinksAsync(SharedDriveID, fullPath, "path", "users", "edit");
        var driveItem = await oneDrive.DriveItemInfoAsync(SharedDriveID, fullPath, "path");
        var wordExtensions = new List<String>{".doc", ".docx", ".dotx", ".odt"};
        var excelExtensions =  new List<String>{".xlsx", ".xlsm", ".xls", ".xlsb", ".xltx", ".xlt"};
        var powerPointExtensions =  new List<String>{".ppt", ".pptx", ".pptm", ".potx", ".pot", ".potm", ".ppam", ".ppa", ".thmx"};
        var adobeExtensions =  new List<String>{".pdf"};
        var currentFileExtension = Path.GetExtension(driveItem.WebDavUrl).ToLower();

        if(wordExtensions.Contains(currentFileExtension)) 
        {
            return Ok("ms-word:ofe|u|"+driveItem.WebDavUrl);
        } else if (excelExtensions.Contains(currentFileExtension)) 
        {
            return Ok("ms-excel:ofe|u|"+driveItem.WebDavUrl);
        } else if (powerPointExtensions.Contains(currentFileExtension))
        {
            return Ok("ms-powerpoint:ofe|u|"+driveItem.WebDavUrl);
        } else if (adobeExtensions.Contains(currentFileExtension))
        {
            return Ok("odopen://"+driveItem.WebDavUrl);
        }
        return Ok(SharedLinkResponse.Link.WebUrl);
    }

It is unclear if odopen:// is the correct start. If you try it in onedrive and monitor the network requests I see

odopen://openFile/?fileId=blasdflasdflas&siteId=asdfsadfsdfsdf&listId=%7Bd02b7574%2D2dfasdfasdfa&userEmail=john%2EDoe%40test%2Esomething%2Ecome&userId=dfsdfsf5&webUrl=dfasdfasfdsadfsadfasdfsadf

So maybe I need to compile all of this for it to work? Or even better maybe I can get ms graph to generate this somehow for me to make my life easier?
