How Unity3d Supports System.Numerics

0. Description:
Thanks to the person who browsed this post, because my English is not very good, so this is a machine translation.

1. The problem:

Platform: Unity3d 2017.3.1 Language: C#
Because the need to reference System.Numerics, Unity's solution project does not support direct reference dll
So I'm from C: Program Files (x86)Reference AssembliesMicrosoftFramework.NETFrameworkv4.6
Found under System.Numerics.dll import to Assets, there was an error. (I have chosen Script Runtime Version as .Net 4.6 in Edit - Project Settings - Player - Other Settings)

2. Code:



You can see that the System.Numerics.BigInteger class can run, but this error dll seems to affect my other code.

3. Error information:



4, Which methods have been tried:

I tried to put Assets in System.Numerics.dll using .Net 3.5.
It has not been resolved yet.

5. Thanks

C: Program Files (x86)Reference AssembliesMicrosoftFramework.NETFramework

System.Numerics can be found in this directory. Interested ones can be imported into Unity to find the problem.

 

Thank you for reply!

But I only found System.Numerics.dll in C:\Program Files\Unity 2017.3.1f1 (64-bit)\Editor\Data\MonoBleedingEdge\lib\mono\4.5-api


Then I created two files in my Unity Asset.


But the error still there.



What's wrong with my step?

 

I really really thanks for your help!

I found System.Numerics.dll and System.Numerics.Vectors.dll in
<UnityInstallDir>\Editor\Data\MonoBleedingEdge\lib\mono\4.5
not in
<UnityInstallDir>\Editor\Data\MonoBleedingEdge\lib\mono\4.5-api

It seems does not need to created msc.rsp and csc.rsp

Thank you!
