Can not decode the source ocde of Microsoft.AspNetCore.Identity.dll version 6.0.16 · Issue #216 · dnSpyEx/dnSpy · GitHub

Describe the Bug

The source code decode does not work for C:\Program Files\dotnet\packs\Microsoft.AspNetCore.App.Ref\6.0.16\ref\net6.0\Microsoft.AspNetCore.Identity.dll, the corresponding nuget library is https://www.nuget.org/packages/Microsoft.AspNetCore.App.Ref/6.0.16

public class SignInManager where TUser : class
The method body for PasswordSignInAsync is throw null

 

解答:

Here is the answer from GPT-4:

The "Ref" refers to "Reference" in the filename Microsoft.AspNetCore.App.Ref.dll.

Microsoft.AspNetCore.App.Ref.dll is part of the .NET Core shared framework and includes reference assemblies, or assemblies that contain just metadata of the types in the package and no actual implementation.

These reference assemblies are used at compile time for type resolution, so the compiler can confirm that the used .NET APIs are valid and types can be resolved. At runtime, an application uses the actual runtime assemblies found in the shared framework, not these reference assemblies.

---

Hint: compare your dll with the one located at C:\Program Files\dotnet\shared\Microsoft.AspNetCore.App\6.0.16\Microsoft.AspNetCore.Identity.dll

 

it works when I load the assembly from the shared folder, tick the "decompile async methods" is required

 

and the code maps to https://github.com/dotnet/aspnetcore/releases/tag/v6.0.16 on commit d6f154cca3863703cf87c8b840eea9cbe20229b2
