Solution:

 private static void ProcessTemplate(Stream template, Dictionary toReplace)
        {
            using (var workbook = SpreadsheetDocument.Open(template, true, new OpenSettings { AutoSave = true }))
            {

                workbook.WorkbookPart.Workbook.CalculationProperties.ForceFullCalculation = true;
                workbook.WorkbookPart.Workbook.CalculationProperties.FullCalculationOnLoad = true;

                //Replace  SheetNames
                foreach (Sheet sheet in workbook.WorkbookPart.Workbook.Sheets)
                    foreach (var key in toReplace.Keys)
                        sheet.Name.Value = sheet.Name.Value.Replace(key, toReplace[key]);

                foreach (WorksheetPart wsheetpart in workbook.WorkbookPart.WorksheetParts)
                    foreach (SheetData sheetd in wsheetpart.Worksheet.Descendants())
                        foreach (Row r in wsheetpart.Worksheet.Descendants())
                            foreach (Cell c in r.Descendants())
                                if (c.CellFormula != null)
                                {
                                    foreach (var key in toReplace.Keys)
                                        c.CellFormula.Text = c.CellFormula.Text.Replace(key, toReplace[key]);
                                }

                                // Replace shared strings
                                SharedStringTablePart sharedStringsPart = workbook.WorkbookPart.SharedStringTablePart;

                IEnumerable sharedStringTextElements = sharedStringsPart.SharedStringTable.Descendants();
                for(int i =0;i sharedStringTextElementsF = sharedStringsPart.SharedStringTable.Descendants();
                for (int i = 0; i < toReplace.Keys.Count; i++)
                    DoReplaceFormula(sharedStringTextElementsF, toReplace);

                // Replace inline strings
                IEnumerable worksheetParts = workbook.GetPartsOfType();
                foreach (var worksheet in worksheetParts)
                {

                    var allTextElements = worksheet.Worksheet.Descendants();
                    DoReplace(allTextElements, toReplace);

                    var allTextElements2 = worksheet.Worksheet.Descendants();
                    DoReplaceFormula(allTextElements2, toReplace);

                }

            } // AutoSave enabled
        }
