I have seen this error for other user's, even in this forum. But not in my particular context. I have built a silverlight reporting application which is using wcf and entity framework for data retrieval. Everything seems to work fine initially but after
having run through several reports I get the error above on calls that initial were working. In other words there seems to be some sort of resource issue in my code somewhere. Unfortunately that line is the only error I'm getting back. But I do suspect that
the exception itself is coming from somewhere in the following code:
public T GetPatchInventoryByQueryString<T,I>(string queryStr)
where T : IList<I>
where I : IPatchInventory
{
EntityConnection econn = new EntityConnection("name=LDMS861Entities1");
try
{
IList<PatchInventory> patches = _container.Resolve<IList<PatchInventory>>();
if (econn.State == ConnectionState.Closed)
econn.Open();
using (econn)
{
using (EntityCommand scmd = new EntityCommand(queryStr, econn))
{
using (EntityDataReader edr = scmd.ExecuteReader(CommandBehavior.SequentialAccess))
{
while (edr.Read())
{
patches.Add(GetPatchInventoryByDataRecord<PatchInventory>(edr));
}
}
return (T)patches;
}
}
}
finally
{
if (econn.State == ConnectionState.Open)
{
econn.Close();
econn.Dispose();
}
}
}
