Where is my System.Numerics namespace?
Solution 1
You need to add an assembly reference to System.Numerics.dll
The MSDN entry on BigInteger states:
BigInteger Structure
...
Namespace: System.Numerics
Assembly: System.Numerics (in System.Numerics.dll)
Solution 2
Though most assemblies are the part of the installation, VS does add only some core elements to the reference list of a project (Core, Data, XML etc.). One needs to add other references by hand using Reference Manager.
Right-click your project, then select Add Reference
(or Add->Reference
). System.Numerics
resides in Assemblies. Then you can use using System.Numerics;
in project files.

For years I developed ILE RPGIV software for the IBM AS/400 iSeries midrange computer. I made the leap to .Net years ago and love it. I've worked in a variety of industries from manufacturing, financial, and defense. I'm constantly amazed that even to this day, I learn something new every single day.

I'm using Visual Studio 2010 and trying to use the
BigInteger
type in a C# program. This type is supposed to be available inSystem.Numerics
namespace, but I don't seem to have that installed in the .Net 4.0 framework. When I type "using System.Numerics;
" in VS2010, a red underline appears under the "Numerics
". Has anyone else ever had this problem?If so, how do you resolve it? I just re-downloaded and re-installed (repaired) the .Net 4.0 framework, but that didn't help. I've never had any problems with other C# programs that I've written, so I'm wondering what I'm missing.
