In 5216e0d ("fix: make Mock{File,Directory}Info cache file attributes (TestableIO#791)", 2022-01-09) a cache of the MockFileData was introduced, to mimic the behaviour that a FileInfo object will not read the data from disk but instead also remembers its internal state, which can be updated by calling its `Refresh` method. This internal (or cached state) is invalidated when calling the methods `Create`, `Delete` and `MoveTo` methods, as can be seen by the `Invalidate` calls in https://github.com/dotnet/runtime/blob/8766a1cf1ed6c3b69cef50154139699b72fb52c5/src/libraries/System.Private.CoreLib/src/System/IO/FileInfo.cs In the PR TestableIO#791 it was overlooked to also invalidate the cached data in these methods. This commit fixes it by invalidating the cached data only for `Create`, `CreateText` and `Delete`. The two `MoveTo` variants are not changed as I could not manage to find any behaviour which is broken without that invalidation. Most likely reason is that the MockFileData is updated to represent the destination file ofter the move, so invalidating is not needed. Fixes TestableIO#822
