CreateBlendState1 Error - .NET 5.0 not supported.

[h1cks]

Updated my project to the latest vortice, CreateBlendState1 is throwing an error

Could not load file or assembly 'System.Runtime.CompilerServices.Unsafe, Version=6.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'. The system cannot find the file specified.

Stack trace is

The blendstate I created was:

   BlendDescription1 blendStateDescription_;
    blendStateDescription_ = new BlendDescription1()
    {
        AlphaToCoverageEnable = false
    };
    blendStateDescription_.RenderTarget[0].IsBlendEnabled = true;
    blendStateDescription_.RenderTarget[0].SourceBlend = Blend.SourceAlpha;
    blendStateDescription_.RenderTarget[0].DestinationBlend = Blend.InverseSourceAlpha; //
    blendStateDescription_.RenderTarget[0].BlendOperation = D3D11.BlendOperation.Add;
    blendStateDescription_.RenderTarget[0].SourceBlendAlpha = Blend.One; //Zero
    blendStateDescription_.RenderTarget[0].DestinationBlendAlpha = Blend.Zero;
    blendStateDescription_.RenderTarget[0].BlendOperationAlpha = D3D11.BlendOperation.Add;
    blendStateDescription_.RenderTarget[0].RenderTargetWriteMask = ColorWriteEnable.All;

Will close is this is a usage issue.

Not sure what CompilerServices.Unsafe has to do with the issue, make sure you can create and example application so I can reproduce it

[h1cks]

I am running under .net 5.

Might up to 6.

[h1cks]

@amerkoleci Update: Moving from .NET 5 to 6 fixed it.

[h1cks]

@amerkoleci found the issue, I was running under .NET 5.0

The __MarshalTo looks like a .NET 6.0 function. I checked the stack and found "Feature not supported" on that function.

[h1cks]

Issue is .net 5.0 vs .net 6.0. Simply compiling my game under .net 5.0 I could reproduce.

The current targets are netstandard 2.0 and net 6.0. Idk if net 5.0 would try to use the netstandard library. Upgrading may be the best path.

Totally agree

[h1cks]

I will update. More an issue of whether it can enforced minimum version of .net

I remember facing this issue with .NET and I just had to upgrade the package System.Runtime.CompilerServices.Unsafe to ver.6.
