HRESULT: 0x81070201 Exception

HRESULT: 0x81070201 Exception
Okay okay, this is actually something very basic, but it happend now a couple of times to me. If you work on a Feature that defines a custom SharePoint List, you can run into the following Error while activating it (in this case during Site Provisioning by definitions in onet.xml):

The element 'MyList' of type 'ListInstance' for feature 'MyListFeature' (id: 794958c5-fede-4e1f-aa96-d9fcd087945e) threw an exception during activation: Exception from HRESULT: 0x81070201

The reason for this error is, that SharePoint can't find the related schema.xml file for the list to define. This can happen, if


You simply forgot to write an schema.xml file

or, what is more realistic, the Name Attribute in ListTemplate is not the same as the Folder Name you have the schema.xml File stored in.

The Name-value of the ListTemplate tag must match the name of the folder you have your schema.xml file stored in:


Name="MyListDefinition"
Category="Custom Lists"
DisplayName="MyList"
...
