[CLOSED] Change Source code and take new Ext.net dll Ext.Net 4.2

[Geovision]

Hello,

I downloaded the source code from github and I modified this code block:

  if (sm) {
                  if (sm instanceof Ext.grid.selection.SpreadsheetModel) {
                     (sm.grid.ownerGrid || sm.grid).un("selectionchange", this.updateSelection, this);
                     (this.grid.ownerGrid || this.grid).un("selectionchange", this.updateSelection, this);
                  } else {
                      sm.un("selectionchange", this.updateSelection, this);
                  }

Step 1: Downloaded the source code from github
Step 2: Open the downloaded source code in Visual Studio 2013 (Ext.NET.vs2013.sln)
Step 3: Change the code block above to solve the issue reported on the forums about change selection model from spreadsheet to any other selection model
Step 4: Rebuild Ext.Net vs 2013 solution to get the new Ext.Net dll
Step 5: Go to "Premium-master\src\bin\Debug" and take the new dll
Step 6: Open my customized application project that uses the Ext.net tech.
Step 7: Delete from referenced the old Ext.Net.dll and reference to the new one
Step 8: Rebuild the solution (my application)
Step 9: I am getting the errors shown in the attached image. As like that no Ext.net library in my application. Ext.net components and code are not recognized any more.

WE ARE ROLLING BACK NOW TO EXT.NET 4.1

Thank you.
