我尝试在另一台装有 VS 16.4.4 的机器上运行测试，以防它是 Visual Studio 预览版的问题，但问题又出现了.
在我的框架测试项目中，我尝试

我想知道 这个关于 entityframework.core 的问题 是相关的，但我只能在 Nuget 上找到 Microsoft.EntityFrameworkCore.
[更新单元测试现在有效]
我现在可以进行单元测试了.我需要在单元测试项目
的顶部附近包含以下内容 <AutoGenerateBindingRedirects>true</AutoGenerateBindingRedirects><GenerateBindingRedirectsOutputType>true</GenerateBindingRedirectsOutputType></PropertyGroup> 正如在这个问题中所讨论的那样关于程序集绑定
但是我仍然需要解决在 VB6 中使用我的 com 可见库
解决方案
我一直在为完全相同的问题而苦苦挣扎并且能够解决它.
就我而言，问题 DLL 是 Microsoft.Extensions.Logging.这是我的例外:
无法加载文件或程序集System.IO.FileNotFoundException:无法加载文件或程序集"Microsoft.Extensions.Logging，版本=2.2.0.0，文化=中性，PublicKeyToken=adb9793829ddae60' 或其依赖项之一.该系统找不到指定的文件.解决方案非常简单，基本上 app.config 适用于使用 COM 公开的 .NET 类的 VB6 EXE.您只需要使用 <assemblyBinding> 标签创建一个常规的 app.config，它就会起作用.棘手的部分是该配置的放置位置以及如何命名.
- 当您从 IDE (VB6) 运行 EXE 时，在
C:Program Files (x86)Microsoft Visual StudioVB98中创建 VB6.exe.config.创建配置后，不要忘记重新启动 IDE. - 当您从 EXE 直接运行时，在与您的 ExeName.exe 相同的文件夹中创建 ExeName.exe.config
这里是关于它如何在更改后解决重定向的 Fusion 日志(从 IDE 案例运行):

If it were not for the com-visible aspect, this question would be a duplicate of this question on assembly binding. I had struggled for days because I did not realize that I needed to alter my unit test project as well as the com visible project. If you don't want to read through my struggles realizing this, skip to the last update.
[Pre-amble]
I feared it may be a bridge to far trying to access a dotnet standard 2.0 library from VB6 via a COM Visible Framework 4.7.2 library, but wanted to try.
Hello World does work. ( i.e calling a simple function that returns a string )
However I get this error when I try and run the VB6 program via the IDE or as a .EXE.
The error message indicates the problem is occuring in the code of the c# dotnet standard2.0 library.
System.IO.FileNotFoundException: Could not load file or assembly 'Microsoft.Extensions.DependencyInjection.Abstractions,
Version=3.1.0.0, Culture=neutral,
PublicKeyToken=adb9793829ddae60' or one of its dependencies.
The system cannot find the file specified.
File name: 'Microsoft.Extensions.DependencyInjection.Abstractions, Version=3.1.0.0,

at Microsoft.EntityFrameworkCore.DbContext..ctor(DbContextOptions options)
at SBDSTD.Standard.Entities.ApiDbContext..ctor(DbContextOptions options)
at SBDSTD.Standard.Services.Helper.MakeContext(String connectionString)
The library code where the error is occurs is
public static ApiDbContext MakeContext(string connectionString)
{
var optionsBuilder = new DbContextOptionsBuilder<ApiDbContext>();
optionsBuilder.UseSqlServer(connectionString );
var options = optionsBuilder.Options;
return new ApiDbContext(options); // Error occurs here
}
The context class contains
public class ApiDbContext : DbContext
{
public ApiDbContext(DbContextOptions<ApiDbContext> options)
: base(options)
{
}
// etc
I managed to work around the issue by creating a Framework console exe , then getting vb6 to shell out to it.
Dim num As Long
num = ShellSync(cmd, vbMinimizedNoFocus)
Where code for shellsync is in a module
Option Explicit
Private Const INFINITE = &HFFFFFFFF
Private Const SYNCHRONIZE = &H100000
Private Const PROCESS_QUERY_INFORMATION = &H400&
Private Declare Function CloseHandle Lib "kernel32" ( _

ByVal dwMilliseconds As Long) As Long
Public Function ShellSync( _
ByVal PathName As String, _
ByVal WindowStyle As VbAppWinStyle) As Long
'Shell and wait. Return exit code result, raise an
'exception on any error.
Dim lngPid As Long
Dim lngHandle As Long
Dim lngExitCode As Long
lngPid = Shell(PathName, WindowStyle)
If lngPid <> 0 Then
lngHandle = OpenProcess(SYNCHRONIZE _
Or PROCESS_QUERY_INFORMATION, 0, lngPid)
If lngHandle <> 0 Then
WaitForSingleObject lngHandle, INFINITE
If GetExitCodeProcess(lngHandle, lngExitCode) <> 0 Then
ShellSync = lngExitCode
CloseHandle lngHandle
Else
CloseHandle lngHandle
Err.Raise &H8004AA00, "ShellSync", _
"Failed to retrieve exit code, error " _
& CStr(Err.LastDllError)
End If
Else
Err.Raise &H8004AA01, "ShellSync", _
"Failed to open child process"
End If
Else
Err.Raise &H8004AA02, "ShellSync", _
"Failed to Shell child process"
End If
End Function
Interestingly if I call shell instead of shellsync I get the error

[Update]
I added the following to my code to the com visible library
[DispId(2)]
[ComVisible(true)]
public string ReferenceCheck()
{
var factory = new Microsoft.Extensions.DependencyInjection.DefaultServiceProviderFactory();
return "";
}
but it did not help.
I tried to use Fuslogvw but the log viewer is empty, even after I change the settings to Log in exception text and attempt to troubleshoot
I tried using Procmon and can see the following sort of thing
I also tried to find the Modules window from the Debug menu but dont see it.
Checking This link
[Update]
I notice I have assembly binding logging turned off.
But when I look in RegEdit it is already 1
[Update]
After reading Hans Passant's comment In the com visible library I added some code to resolve assemblies
My test method in the com visible library shows the following error information.

[Update]
This issue on GitHub seems related
I tried reinstalling the c** redistributable
[Update]
I finally got Fuslogvw to work with the help of this question
Which references 2 versions of the problem library.
I also noticed that my standard library has an analyzer complaining
0} is an internal API that supports the Entity Framework Core infrastructure and not subject to the same compatibility standards as public APIs. It may be changed or removed without notice in any release.
[Update]
If I make a .exe in my com visible framework project, and run it , there is no problem. The problem occurs if I try a unit test.
Fusion log shows the following

I note some version differences!
I tried running the test on a different machine with VS 16.4.4 in case it was an issue with the Preview version of Visual Studio, however the problem was repeated.
In my framework test project I tried installing the 3.1.1 version of Microsoft.Extensions.DependencyInjectionAbstractions and noticed a warning

I retried Simon's advice to install microsoft.data.sqlclient.sni manually
but still got the error
Could not load file or assembly 'Microsoft.Extensions.DependencyInjection.Abstractions, Version=3.1.0.0
I also tried downloading the 1.1.1 version of microsoft.data.sqlclient.sni
[Update] I decided to try rolling back entity framework in the .netstandard2.0 project to use
<PackageReference Include="Microsoft.EntityFrameworkCore" Version="3.1.0" />
<PackageReference Include="Microsoft.EntityFrameworkCore.SqlServer" Version="3.1.0" />
Now when I unit test with the com visible framework project I get
System.Exception: vivadbridgestd:GetValidCarriers line: 20 error:System.Exception: kg1System.IO.FileLoadException: Could not load file or assembly 'System.ComponentModel.Annotations, Version=4.2.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies.

This causes my exe to fail as well.
Then I tried the 3.1.0 version of EFCore I now get the following in the framework test project

also happening in the .exe
I wondered if this question about entityframework.core is related but I can only find Microsoft.EntityFrameworkCore on Nuget.
[Update unit test now works]
I now have my unit test working. I needed to include the following near the top of the unit test project
<PropertyGroup>
<AutoGenerateBindingRedirects>true</AutoGenerateBindingRedirects>
<GenerateBindingRedirectsOutputType>true</GenerateBindingRedirectsOutputType>
</PropertyGroup>
As discussed in this question on assembly binding
However I still need to a work around to use my com visible library in VB6
解决方案
I've been struggling with exactly the same problem and was able to solve it.
In my case the problem DLL was Microsoft.Extensions.Logging. Here's my exception:
Could not load file or assembly 'System.IO.FileNotFoundException: Could not load file or assembly 'Microsoft.Extensions.Logging,
Version=2.2.0.0, Culture=neutral,
PublicKeyToken=adb9793829ddae60' or one of its dependencies.
The system cannot find the file specified.
The solution was insanely simple, basically app.config works for your VB6 EXE that is consuming COM exposed .NET classes. You just need to create a regular app.config with your <assemblyBinding> tags and it will work. The tricky part is where to place this config and how to name it.
- When you run your EXE from IDE (VB6) create VB6.exe.config in
C:Program Files (x86)Microsoft Visual StudioVB98. Don't forget to restart the IDE after you created the config. - When you run from EXE directly create ExeName.exe.config in the same folder as your ExeName.exe
Here's the Fusion log on how it resolves the redirection after the change (run from IDE case):
Calling assembly : Unity.Microsoft.Logging, Version=5.11.1.0, Culture=neutral, PublicKeyToken=489b6accfaf20ef0.
