SharePoint designer 2013 打开工作流报错

前段时间，工作流突然报错如下：



整个应用下的网站集工作流都会出现这个错误，其他应用程序却不会出现这个错误。检查ULS日志，发现报错：“Failed to find the XML file at location '15\Template\Features\DM_Feature1\feature.xml“。原来是自己发布的Feature删除时没有删除干净。

使用下面的代码可以检查有哪些feature没有删除干净：

class Program
{
static void Main(string[] args)
{
List<Guid> featIDs = new List<Guid>();
foreach (SPFeatureDefinition featdef in SPFarm.Local.FeatureDefinitions)
{
try
{
Console.WriteLine(featdef.RootDirectory + "-------" + featdef.Id.ToString() + "-------" + featdef.GetTitle(System.Threading.Thread.CurrentThread.CurrentCulture));
if (featdef.Id.ToString() == "8a40de38-6810-4187-9637-a6d8df08a43b")
{
Console.WriteLine("################################################");
}

if (featdef.Id.ToString() == "bff4e34b-6303-4ef2-959b-bd27197b3974")
{
Console.WriteLine("################################################");
}
}
catch
{

//This code will be executed if the feature does not have the manifest file.
Console.WriteLine("################################################");
Console.WriteLine("Error Ocurrred! Attempting to get feature ID of the feature without manifest file...:");
Console.WriteLine(featdef.Id.ToString());
}
finally
{
Console.WriteLine();
Console.WriteLine("Press enter to view next feature");
// Console.ReadLine();
}

}

}
}

解决方法：

根据featureid，我在C:\Program Files\Common Files\microsoft shared\Web Server Extensions\15\TEMPLATE\FEATURES下创建DM_Feature1，模拟原先删除掉的xml文件

使用命令Uninstall-SPFeature -Identity -Guid -force删除。最终解决问题。
