If you are considering an update to your .NET Framework to .NET 2.0 then I’m assuming that you are also looking at updating to Visual Studio .NET 2005. If so, then your Cognos SDK projects will require a little updating.
If you are developing your Cognos SDK applications in Visual Studio .NET 2003 then you will require the following .dlls added to your C# or VB.NET projects -- cognosdotnet.dll, and cognosdotnetassembly.dll.
If you are updating your VS.NET studio to VS.NET 2005 then you will reference the updated Cognos SDK .dlls provided with your Cognos 8.2 install. The files are also found in the …install path\Cognos\c8\sdk folder and they are named -- cognosdotnet_2_0.dll, and cognosdotnetassembly_2_0.dll.
The latter .dlls are only available to be used with VS.NET 2005.
