Rider - Nuget Package cannot be used in Code after a few seconds?

I'm using Rider to write code in for Unity.
Rider has Nuget integration and I need to install a dependency (CsvHelper).

So I Installed the CsvHelper Package (you can choose the scope, I chose Assembly-C-Sharp, but you can also Choose "Solution" , both don't work.

After that, the Package can be used in the Code,

Code (CSharp):

1. using CsvHelper;
2.  

It will work for a short time, and you can open the Class and decompile it with jetbrains rider.

But like 10 Seconds later, Rider can't use the package in the code anymore:

The Package is still available

Code (CSharp):

1. // Assembly location: /Users/grauen/RiderProjects/Demo/packages/CsvHelper.15.0.5/lib/net47/CsvHelper.dll
2.  

When Compiling there is an error:

Code (CSharp):

1. LocalizedDialogResolver.cs(4, 7): [CS0246] The type or namespace name 'CsvHelper' could not be found (are you missing a using directive or an assembly reference?)

Can you help me?

 

I noticed that there is an Folder "References -> Assemblies", I can import the dll here. Then everything works - I can even build the project. But then the dll seems to disappear again.

Edit: might be related but didn't help me though:

Okay I got it - you have to add the Dll to the asset folder.

I'm trying to get this to work as well and I can't figure it out. I have followed what you did and I keep getting errors.

What I did was installed CsvHelper package through NuGet. The reference is added in Visual studio. Then I added the dll to the assets folder in Unity.

I get these error:

Assembly 'Assets/CsvHelper.dll' will not be loaded due to errors:
Unable to resolve reference 'Microsoft.Bcl.AsyncInterfaces'. Is the assembly missing or incompatible with the current platform?
Reference validation can be disabled in the Plugin Inspector.

Unable to resolve reference 'System.Threading.Tasks.Extensions'. Is the assembly missing or incompatible with the current platform?
Reference validation can be disabled in the Plugin Inspector.

Have you had these errors before?

 

I figured it out. CsvHelper installs other packages. Microsoft.Bcl.AsyncInterfaces and System.Threading.Tasks.Extensions. I added their dlls from their package locations and added them to the Assets folder.

 

Hi @valdeezzee ,
thanks for the info.

It looks like Rider has a bug anyway which causes that you cannot resolve dependency classes anymore.

By the day : I switched to Json, which is supported by unity out of the box.

Hi @valdeezzee, I couldn't seem to find the other dll's when I downloaded the CsvHelper .nuget where did you find yours? where did you find the Microsoft.Bcl.AsyncInterfaces dll?

 

@Estellise-Yukihime In Visual Studio go to your Solution Explorer. In there you should see a section named Assembly-CSharp-firstpass. Under that section, there should be a References section. Search for your dll.



Once you find the dll, select it. In your Properties window, it will show the path where your dll is located.
