Name 'Lassalle' is not declared

Question

I am getting following errors while trying to build a solution, which are probably due to missing or corrupt Lassalle.Flow DLL files. My question is how can I reinstall or repair this .dll does this file comes with .Net installation so that reinstalling the framework would solve it?

Or is there a way I can download the .dll and replace it in my system32 folder? I am using windows XP.

Answer 1

No, those DLLs are not part of the .NET Framework, so repairing or re-installing the .NET Framework will not solve this problem. These DLLs are from a third party called Lassalle Technologies

Verify in your Visual Studio project's References folder that the path to these DLLs is correct. There will be a red exclamation point or yellow triangle next to the DLL if there is an issue with it.
