IdentityModel 因“无法加载文件或程序集‘System.Numerics.Vectors，Version=4.1.4.0’”而中断

Question

We have a .NET Framework 4.7.1 project

I installed IdentityModel 6.0.0 with the NuGet Package Manager. It installed the following dependencies for me:

Microsoft.Bcl.AsyncInterfaces 6.0.0
System.Buffers 4.5.1
System.Memory 4.5.4
System.Numerics.Vectors 4.5.0
System.Text.Json 6.0.3
System.ValueTuple 4.5.0

I'm trying to run the following code to see if a service exists:

var disco = await clientAuth.GetDiscoveryDocumentAsync(new DiscoveryDocumentRequest
{
    Address = server,
    Policy =
    {
        ValidateIssuerName = false
    }
});
if (disco.IsError) {...}

But, it keeps generating an error. I managed to drill down into the code, and finally came upon this: var result = System.Text.Json.JsonDocument.Parse("{"issuer":"https:....}").RootElement;

The error I get on this is:

Could not load file or assembly 'System.Numerics.Vectors, Version=4.1.4.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The system cannot find the file specified.

I managed to drill down to the ConsumeString method, but couldn't learn anything.

The most annoying of all is I can't load version 4.1.4 for System.Numerics.Vectors

In the Nuget Manager, only the following versions are available:

4.5.0 - current
4.4.0
4.3.0
4.1.1
4.1.0
4.0.0

I'm getting preciously little on the inte.net regarding this specific issue, and I've tried everything I could find without any luck. I've tried clearing my nuget cache. I can't remember how many times I've removed and readded the dependencies, I've cleaned my solution and rebuild it. I tried a number of combinations of:

<dependentAssembly>
    <assemblyIdentity name="System.Numerics.Vectors" publicKeyToken="b03f5f7f11d50a3a" culture="neutral" />
    <bindingRedirect oldVersion="0.0.0.0-4.5.0.0" newVersion="4.1.4.0" />
</dependentAssembly>

Answer 1

Turns out that adding the following line in your root project file will magically make all the problems go away:

<AutoGenerateBindingRedirects>true</AutoGenerateBindingRedirects>

Odd that I didn't find any article suggesting this.
