AJAX Control Toolkit – Could not load file or assembly vjslib

I wanted to play around with ASP.NET AJAX Control Toolkit. There are a few steps to do before you can start using this tool. Among others, you need to build the Visual Studio Solution provided in the downloaded zip file.

When I tried to build the solution I got this error:

Error 1 Could not load file or assembly ‘vjslib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a’ or one of its dependencies. The system cannot find the file specified. C:\Program Files\Microsoft ASP.NET\Ajax Control Toolkit\TemplateVSI\TemplateVSI.csproj 60 5 TemplateVSI

Solution

This is what AJAX Control Toolkit documentation says:

The TemplateVSI project has a dependency on vjslib.dll which is a part of the Visual J# Redistributable…

The above mentioned package can be found there. Installing it solved this problem, at least on my computer.
