Hi all,

This might not be the correct forum but i need to know this issue.

Actually , i installed Coolite Toolkit - Version 0.7.0 in my system  and i have Visual Studio 2005 . So i have only dotnet framework 2.0 installed in my system.

I put few controls in my application for R&D and while running i am getting the exception saying,

 TargetInvocationException was unhandled by user code.

The InnerException says,

Could not load file or assembly 'System.Core, Version=3.5.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' or one of its dependencies. The system cannot find the file specified. 

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. 

I found a link here http://www.coolite.com/forums/Topic1765-16-1.aspx#bm1849 that says that i have to have Framwork Version 3.5 installed .

So, my question is, is this the sollution?

I mean if i install Framework 3.5 then will the problem be resolved?

If anyone faced this situation kindly let me know the workaround.

Thanks to all

 Sounds like the solution to me.

 You can install .net 3.5 without it affecting any of your other asp.net 2.0 projects - it just acts as a layer on top of 2.0

That's True, your exception stack trace itself asking for that System.Core dll, which comes only with .NET 3.5, its a New assembly in .NET Framework, also you have got instruction from toolkit vendor itself to have .NET 3.5 installed on usage machine, so its better you install .NET 3.5 framework, may be you may need more dll's of 3.5 framework to make that toolkit work. thats the best solution you can get, and nothing to panic ab't installing 3.5, its clean.

to know about System.core class visit this link http://blogs.msdn.com/pedram/archive/2007/11/07/system-core-dll-of-net-framework-3-5.aspx
