System.DllNotFoundException: Unable to load DLL 'raylib'

[Shadowblitz16]

this needs to be fixed.
I followed the instructions in the readme and it doesn't work.

If we need to copy the native library to the root of the project it should say so it the readme's nuget section

[chrisdill]

The library only needs to be copied if you are installing manually so the readme is fine. If you installed the nuget package and it fails to load raylib then that is a bug.

[Shadowblitz16]

its a bug then

I have also installed the nugget package, and have this problem.

@Shadowblitz16 Are you using the NuGet package? If you are using the NuGet package then this is a duplicate of #43

Where did you put the native library?

[Shadowblitz16]

@9ParsonsB I put it in the root of the project and then marked its as copy to output 'always'

[9ParsonsB]

@Shadowblitz16 Can you see raylib.dll in the output directory? (Generally in /Debug/Bin/)
What architecture of the raylib dll did you download, the x86 or x64? and was it the msvc version?

[Shadowblitz16]

I'm pretty sure it was in /Debug/Bin/ because I used other native libraries before and they have worked
I downloaded the msvc version I beleave

[chrisdill]

@9ParsonsB It seems 3.1.8-pre and 3.1.8-pre2 do not include the native runtimes as expected meaning users could not find the native library when they install the package.

I did not find the issue as I had a system version installed which it found instead. I am surprised I did not find this sooner. Clearly more testing should of been done to prevent this. Currently github actions only builds the C# code. It does not verify the native libraries exist on the target platforms.

[chrisdill]

I updated the README install command to use the version 3.1.5 which is the latest stable release. There was a version for 3.1.6 but that was unlisted due to bugs. Running dotnet add package Raylib-cs for me sets the version to 3.1.6. I expected it to install 3.1.5 which is the latest stable and public version. I am not sure if this is intended or not.

The instructions provided only work for a .net core project.
Using the provided instructions on a .netstandard 2.0 or framework 4.7.2+ does not work.

I got this error:

Unhandled exception. System.DllNotFoundException: Unable to load shared library 'raylib' or one of its dependencies. In order to help diagnose loading problems, consider setting the DYLD_PRINT_LIBRARIES environment variable: dlopen(libraylib, 1): image not found
   at Raylib_cs.Raylib.InitWindow(Int32 width, Int32 height, String title)

I am using Apple Silicon (osx-arm64).

[9ParsonsB]

@ayousuf23 arm platforms are not yet supported. Please ensure you are running in Rosetta 2 or open a separate issue regarding ARM platforms.

[chrisdill]

The nuget package for Raylib-cs uses netstandard2.1 and the runtimes for the supported platforms should load as expected.

Sorry to post late, but I am also getting this issue, was a solution found?

@drum445
This issue relates to the NuGet package and has since been fixed.

Please provide more details on your setup & problem (Platform, architecture, raylib version, error message, etc.) or join the raylib discord server (raylib-cs channel) for support
