Error while writing documentation - The filename, directory name, or volume label syntax is incorrect

Hi, I encountered this error recently:
Unhandled exception.

It looks like this class (and specifically the method I included) are causing the problem:
namespace Hlix.Repository.LLBLGen
{
public class Repository<TEntity> : Repository, IRepository<TEntity> where TEntity : EntityBase2, IDbEntity, IEntity2, new()
{
protected readonly IRepositoryAdapter _repositoryAdapter;
public Repository(IRepositoryAdapter repositoryAdapter) : base(repositoryAdapter.DataAccessAdapter)
{
_repositoryAdapter = repositoryAdapter;
}
public async Task<IEnumerable<TEntity>> FetchEntitiesAsync(
IRelationPredicateBucket bucket,
IPrefetchPath2 prefetchPath,
ISortExpression sortExpression,
int? maxNumberOfItemsToReturn = null,
IDataAccessAdapter dataAccessAdapter = null)
{
var entityCollection = _repositoryAdapter.CollectionFactory<TEntity>();
await base.FetchEntitiesAsync(entityCollection, bucket, prefetchPath, sortExpression, maxNumberOfItemsToReturn, dataAccessAdapter);
return entityCollection.AsEnumerable();
}
// A bunch of other methods here
}
}It could be due to a long file name that it generates (Git complained about the long filename) or the special characters. Any ideas? If you need more info, please let me know, and I'll provide whatever I can.
Thanks!
Another detail - when I remove the -u true flag (IncludeUndocumentedItems), I don't get any errors. But it generates a different set of files then. Please see the visual Git diff of filenames:
(I would expect to see quite a bit more files being generated here btw, I assume the process just stopped when it encountered the error.)
it is probably indeed because of file name too long, see #57 (comment) you can change the naming strategy to produce shorter name, see if this solve your issue :)
Awesome, thanks for the quick reply. I switched to NameAndMd5Mix and have no more crashes now. Thnx!
