Hi

I'm trying to update from Telerik.Documents.Spreadsheet 2020.3.915 to 2020.3.1019

 

 

I get the following exception:

    System.IO.FileNotFoundException : Could not load file or assembly 'Telerik.Zip, Version=2020.3.1019.20, Culture=neutral, PublicKeyToken=5803cfa389c90ce7'. The system cannot find the file specified.

Hello Bart,

It seems that the Telerik.Zip assembly is not referenced. The RadSpreadsheet library is depending on this asembly. Please make sure that this assmbly is referenced, and it has the correct version. Then you can clean and rebuild your project. 

I hope this helps. Should you have any other questions do not hesitate to ask.

Hi Dimitar,

It looks like that the RadSpreadsheet assembly  has a WinFows dependancy. For a .net Standard  app this doesn't look ok.

According to the depencies 
the Telerik.Documents.Spreadsheet.FormatProviders.OpenXml is dependent on:
        Telerik.Documents.Spreadsheet
        Telerik.Documents.Core

Both are installed and I get the same exception

Hi Bart,

The NET Standart version does not depend on WinForms. You can find all the required assemblies in the following article: Assembly References.

If you are still getting the same exception, open the project folder, delete the bin and obj folders and then rebuild the project.  

Let me know how this works on your side.

Apparently that did the trick.
There is no dependency to this library so this must be added manually

    <PackageReference Include="Telerik.Documents.Core" Version="2020.3.1019" />
    <PackageReference Include="Telerik.Documents.Spreadsheet" Version="2020.3.1019" />
    <PackageReference Include="Telerik.Documents.Spreadsheet.FormatProviders.OpenXml" Version="2020.3.1019" />
    <PackageReference Include="Telerik.Zip" Version="2020.3.1019" />
