See, you just came to gripe. No extra clarity. No particular subject. Just: give me something free.
Having someone else do the work and research for you means it's "not free"; it costs time. Someone else's. Which includes asking you to "explain yourself" because you couldn't be bothered to ask a clear question in the first place.

I apologize for thinking "your time" might be better served if you asked "better questions". You're wasting your own time.

Blah, blah blah...
The first thing you need to learn is how to use google. Even people like you - that aren't know-it-alls - need to learn this. If you can't master that simple skill, you won't be successful as a programmer.

That's a nice one for the old guys: "I am so old that I could be successful as a programmer without mastering the skill of using Google." (The main reason being that Google didn't exist then.)

Hello all
I have a project where I from C# code need to use a COM object and consume events.
My COM object can send events by the use of Connectable Objects.
In the good old days when C++ and COM were used, I used the IConnectionPoint and Advice.
But, is there in .NET a way to consume COM events? I guess it will be in the System.Runtime.InteropServices.
|

|

For an early-bound library, you should be able to add event handlers in the same way as any other .NET class.
For a late-bound library, you'll want to use the System.Runtime.InteropServices.ComTypes.IConnectionPoint interface[^], which should be familiar to you from C++. 
IIRC, the event sink parameter to the Advise method needs to be public, [ComVisible(true)], and [ClassInterface(ClassInterfaceType.None)].

When creating a .NET Framework 4.7.2 class library that uses a lot of Microsoft's NuGet packages, and creating an internal NuGet package from the library, is there a way to wrap all those MS packages into the library so that they aren't all required in apps built using my library?
Background:
I've got a legacy .NET Framework 4.7.2 console app, initially deployed a few years ago to an app server using a setup project. Updates and enhancements were deployed by merely copying the exe to the installation location, as well as any new DLLs the enhancements required.
We recently decided to have all our internal applications write their logs to Application Insights in Azure, so I created a .NET Framework 4.7.2 class library with this functionality, and added the 20-odd NuGet packages required (this overhead is insane) to support writing to AI. I built my own NuGet package for this library, uploaded it to our DevOps Artifacts. Then I added my package to the legacy app, and when I built the app it added all those MS DLLs to the obj/Release folder. I copied the new DLLs and the new exe to the deployed folder on the server, but running it fails as it can't find the MS DLLs. Setup projects are no longer supported (why???), so I don't know how to get this to work.
Any ideas?
If you think 'goto' is evil, try writing an Assembly program without JMP.

Would have stuck with the EXE.
Create a (web) server for handling the logging to Azure; your apps talk to the server instead of "NuGet", etc.

That's the problem you need to fix, but unfortunately you haven't provided enough information about it.
You need to get the full exception details to try to diagnose the problem.

System.IO.FileNotFoundException: Could not load file or assembly 'Microsoft.Extensions.DependencyInjection.Abstractions, Version=5.0.0.0, Culture=neutral, PublicKeyToken=adb9793829ddae60' or one of its dependencies. The system cannot find the file specified.

Double-check that the folder your app is running from contains Microsoft.Extensions.DependencyInjection.Abstractions.dll, and that its version is precisely 5.0.0.0.
v5 of that library[^] doesn't have any additional dependencies, so either the file is missing, or you've got the wrong version.

Yep, did that at the beginning of my troubleshooting. All 20 package DLLs are in the same folder as the exe, just as all the previous DLLs it has been using all along have been. All the correct versions, copied from the obj\x64\Release folder where they were pushed to when I built the project.

I am using VS 2019, .Net 4.5.2 on Windows 7.
I have an application which manages a configuration file for another application. The abridged version looks like:
<configuration>
<configSections>
<sectionGroup name="ServiceConfiguration" type="My.ServiceConfiguration" >
<section name="CustomSection" type="My.CustomSection" />
<sectionGroup name="ServiceStepGroups" type="My.StepGroups" >
<sectionGroup name="MyGroup1" type="My.StepGroup" />
</sectionGroup>
</sectionGroup>
</configSections>
<ServiceConfiguration>
<CustomSection />
<ServiceStepGroups>
<MyGroup1 />
</ServiceStepGroups>
</ServiceConfiguration>
</configuration>
When I run the program to modify the configuration file to add a new group with code such as:
namespace My
{
public class StepGroups : ConfigurationSectionGroup
{
public My.StepGroup AddNewGroup()
{
My.StepGroup newGroup = new My.StepGroup();
SectionGroups.Add("MyGroup2", newGroup);
}
}
}
and then save the configuration file I get
<configuration>
<configSections>
<sectionGroup name="ServiceConfiguration" type="My.ServiceConfiguration" >
<section name="CustomSection" type="My.CustomSection" />
<sectionGroup name="ServiceStepGroups" type="My.StepGroups" >
<sectionGroup name="MyGroup1" type="My.StepGroup" />
</sectionGroup>
</sectionGroup>
<sectionGroup name="ServiceConfiguration" >
<sectionGroup name="ServiceStepGroups" >
<sectionGroup name="MyGroup2" type="My.StepGroup" />
</sectionGroup>
</sectionGroup>
</configSections>
<ServiceConfiguration>
<ServiceStepGroups>
<CustomSection />
<MyGroup1 />
<MyGroup2 />
</ServiceStepGroups>
</ServiceConfiguration>
</configuration>
As can be seen, the new MyGroup2 declaration element gets wrapped in a new ServiceConfiguration/ServiceStepGroups construct but 1) AFTER the first construct, 2) WITHOUT type attributes and 3) WITHOUT a CustomSection section; however, the MyGroup2 configuration group IS in the right place in the configuration file below.
Why?
I would have expected the declaration of MyGroup2 to immediately follow the declaration of MyGroup1 without a second construct created.
Digging through the source code and [limited] documentation online has not been fruitful.
Is this a bug? Am I forgetting something?
It should be noted that when I load the new configuration file an exception is thrown (duplicate ServiceStepGroups section group) as would be expected; however, if I manually fix the configuration file as per my expectations previously stated the file loads successfully with the new MyGroup2 included.
Any help or insight is appreciated.
Thanks!

I've never had to save anything from code in the config file, but it would seem that you would want to get the object for the ServiceConfiguration sectionGroup first, add your sectionGroup to that, then resave.

Hi Dave,
Thanks for responding.
Yes, you are correct. Perhaps I was too brief in my code snippet. But I am able to go in with the debugger and everything appears as it should be; the right sections and groups have the right children, etc.
I have written configuration files before but I can't recall if I was attempting to write multiple groups (different names but same type) as I am now. But again, when I make changes manually and read the file back in everything works, which tells me that the internal mechanisms can handle multiple groups (different names but same type) just fine. Hence the perplexing puzzle.
