New version / new internal build

[Rieni De Rijke]

What is the best practice...?

When Telerik comes out with new versions or internal builds, we always try to follow.
We download the files (unblock the dll's) and we copy the files into a (new) directory.
Sometimes we remove all the Telerik dll's from the projects References and we add the new dll's.
Sometimes we unload the projects and replace the telerik version in the text of the projectfiles.
We clean and rebuild our solutions.

This works fine, but... we often have problems with showing the telerik-components in the xaml /designer).
An error shows: Could not load file or assembly 'Telerik.Windows.Controls, Version=2010.3.1304.40...
Yes, we know that Visual Studio's xaml-design-mode is almost useless, but know and than we have to use it...

What are we doing wrong?
What is the best practice to update a solution with a new version or an internal build?

Hi Rieni De Rijke,

I would recommend the first approach - removing the old references and adding them again pointing to the new files. Also, please use the latest internal builds only if necessary (for example you experience a bug that is already fixed). Otherwise, stick to the official release. Cleaning and rebuilding the solution should be enough.
Also, make sure that if your solution contains more than one project to update the references in all of them.
Does restart of Visual Studio help?

The new version of the internal builds is 2010.3.1304.40

We remove the dll's from References.
We add the new dll's from a new Directory. (W:\Development\References\3_part\Telerik\2010.31\)
The dll's are "unblocked".
Clean and rebuild.
Restart Visual Studio.
When opening the projectfile, we see this:

<Reference Include="Telerik.Windows.Controls, Version=2010.3.1110.40, Culture=neutral, PublicKeyToken=5803cfa389c90ce7, processorArchitecture=MSIL">
      <SpecificVersion>False</SpecificVersion>
      <HintPath>W:\Development\References\3_part\Telerik\2010.31\Telerik.Windows.Controls.dll</HintPath>
    </Reference>

When opening xaml in the designer: Could not load file or assembly 'Telerik.Windows.Controls, Version=2010.3.1304.40, Culture=neutral, PublicKeyToken=5803cfa389c90ce7' or one of its dependencies. Operation is not supported. (Exception from HRESULT: 0x80131515)

Hi Rieni De Rijke,

Is the W:\ drive a mapped network share? If so, that could be the problem. You can try to copy the assemblies locally and add the references from there.
Let me know how it goes.

Hi Veselin! Thank you for the quick response!

Removed the dll's from References.
Added them again from C:\Test... (internal builds  2010.3.1304.40)
Clean, Rebuild, Restarted...
Opening the projectfile shows this: (again the old version!).

<Reference Include="Telerik.Windows.Controls.Charting, Version=2010.3.1110.40, Culture=neutral, PublicKeyToken=5803cfa389c90ce7, processorArchitecture=MSIL">
      <SpecificVersion>False</SpecificVersion>
      <HintPath>..\..\..\..\..\Test\2010.31\Telerik.Windows.Controls.dll</HintPath>
    </Reference>

Everything works fine again, but opening xaml in designer:
Could not load file or assembly 'Telerik.Windows.Controls, Version=2010.3.1304.40, ...

Hi Rieni De Rijke,

Are all of the Telerik controls of the same version? Probably you have forgotten to update some of the files.
What happens if you create a blank new application - does it experience the same issue?

Kind regards,
