epplus dispose don't work - dispose

Question

I open with epplus an excel file.
After reading some data, I would like to close the package:
pck.Stream.Close()
pck.Dispose()
Unfortunatelly the excel file is still blocked. I need to close the whole application to get the excel file unlocked.
I have googled, but found nothing useful except the above.

How are you opening the file? The following creates, saves, reopens, prints, and finally deletes all withing the same thread without issue. I can even set a breakpoint anywhere and delete the file. Reading the file this way should not lock the file since it is pulled into memory:
[TestMethod]
public void OpenReopenPrintDeleteTest()
{
//Create some data
var existingFile = new FileInfo(#"c:\temp\temp.xlsx");
if (existingFile.Exists)
existingFile.Delete();
using (var package = new ExcelPackage(existingFile))
{
var workbook = package.Workbook;
workbook.Worksheets.Add("newsheet");
package.Save();
}
using (var package = new ExcelPackage(existingFile))
{
var workbook = package.Workbook;
var worksheet = workbook.Worksheets.First();
//The data
worksheet.Cells["A1"].Value = "Col1";
worksheet.Cells["A2"].Value = "sdf";
worksheet.Cells["A3"].Value = "ghgh";
worksheet.Cells["B1"].Value = "Col2";
worksheet.Cells["B2"].Value = "Group B";
worksheet.Cells["B3"].Value = "Group A";
worksheet.Cells["C1"].Value = "Col3";
worksheet.Cells["C2"].Value = 634.5;
worksheet.Cells["C3"].Value = 274.5;
worksheet.Cells["D1"].Value = "Col4";
worksheet.Cells["D2"].Value = 996440;
worksheet.Cells["D3"].Value = 185780;
package.Save();
}
//Reopen the file
using (var package = new ExcelPackage(existingFile))
{
var workBook = package.Workbook;
if (workBook != null)
{
if (workBook.Worksheets.Count > 0)
{
var currentWorksheet = workBook.Worksheets.First();
var lastrow = currentWorksheet.Dimension.End.Row;
var lastcol = currentWorksheet.Dimension.End.Column;
for (var i = 1; i <= lastrow; i++)
for (var j = 1; j <= lastcol; j++)
Console.WriteLine(currentWorksheet.Cells[i, j].Value);
}
}
}
//Delete the file
existingFile.Delete();
}

I was having the same problem... But I found the solution:
During the "SaveAs" method, I was creating a FileStream that was not being disposed.
Before:
ExcelPackage excel_package = new ExcelPackage(new MemoryStream());
//...
//Do something here
//...
excel_package.SaveAs(new FileStream("filename.xlsx", FileMode.Create));
excel_package.Dispose();
After:
ExcelPackage excel_package = new ExcelPackage(new MemoryStream());
//...
//Do something here
//...
var file_stream = new FileStream("filename.xlsx", FileMode.Create);
excel_package.SaveAs(file_stream);
file_stream.Dispose();
excel_package.Dispose();
Note that the Memory Stream opened during the ExcelPackage declaration was not explicitly disposed, because the last command "excel_package.Dispose()" already does this internally.
Hope it help.
