Created project could not load file or assembly 'Telerik.SvgIcons'

When creating a new project using an older version of the components, there might be mismatch between the version of the installed VS Extentions and the older Telerik Icon assemblies required to build the specific old version of the toolset.

The error will show a message similar to this:

Could not load file or assembly 'Telerik.SvgIcons, Version=4.0.0.0, Culture=neutral, PublicKeyToken=20b4b0547069c4f8' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

You can fix the issue by opening the .csproj file of the project and updating the version of the Icon packages:

    <PackageReference Include="Telerik.FontIcons" Version="4.0.0" />
    <PackageReference Include="Telerik.SvgIcons" Version="4.0.0" />
