That's the wrong public key token. It should be b77a5c561934e089.
Is that a typo in your question? If not, it sounds like his .NET installation is corrupt.

Help with what? You need to explain where you are stuck and what part of your code is not working.

You haven't told us anything about your application.

I suspect the IP address, workstation id, user id, logon type, etc. might give you a clue.

Hello Friends,
I'm developing software that uses the DiscUtils to store files in a container such as a virtual disk (VHD), I'm trying to use Ntfs system with VHD, but I've gone through soo many problems because I store a lot of files with varied sizes. The library generates random exceptions. The idea of using that library was to not spend time creating a file system.
The advantage of DiscUtils is that is native C#, so I can use it with Xamarin.
Well, i need an alternative or help to make it work, I need something that can store various files in a container (like a virtual disk). It can be a library that i use with pInvoke , any other library, or a help on how to use the DiscUtils correctly.
I've tried a thousand forks of DiscUtils.
Thank you, I'm desperate to solve this problem.

..something like a file-archive (like PkZip, LHA), but without the compression?

The only problem with these algorithms is that there is a reconstruction of the file when an entry is removed or added.
What becomes unusable.

Similar to a VHD, a file being modified is being written to. Having hooked a Dokan to a ZIP-file, it simply feels like a file-system.
Alternatively, you'd use a local database.

Do you recommend any particular compression algorithm?

You'd be using it as a file-archive, so I assume you're more interested in speed than getting a good compression. PkZip has (just like some others) the option "not to compress" anything. Meaning you'd have a (or multiple) dumb container(s) for storing/retrieving files.
You may want to create a test-setup and compare this to a local SQLite database; I'm not sure which of the two would perform better.

There are no "random exceptions"; you need to isolate the problem so you can consider an appropriate action (fix; abandon; whatever).
Work with one "file type" at a time instead of a "lot of files" starting out.
|
|

|

This is a backup software so i need it to work with any file type. I've tried to isolate the problem, but it would take a long time to understand the algorithm and fixes it.

That's why they pay you the big bucks.
Seriously, if you have a well-known library that is crashing all the time, then you are probably using it outside the bounds it was intended to be used. I would:
0. RTFM! and check that you are using the APIs correctly.
1. Check for limits on file storage (number of files that may be stored, upper limits on file sizes)
2. Check for limits on container size
3. Check for limits on the file-system containing your container (e.g. FAT32 can only handle files up to 4GB in size)
4. ...
If you have an important point to make, don't try to be subtle or clever. Use a pile driver. Hit the point once. Then come back and hit it again. Then hit it a third time - a tremendous whack.

You should have a good sense of humor to read this question.
I'm writing an unmanaged project to host the .NET Framework CLR (version 4), and execute some of it's code. I'm writing the application in assembly language (but, you don't have to understand assmbly language to understand this question), and I don't have Visual Studio installed on my computer.
Anyway, I've got all the preliminaries working correctly. I've called Enumerate Installed Runtimes, and called ICLRMetaHost.GetRuntime which causes the CLR (version 4) to be loaded but not initialized,...and then, called, ICLRRuntimeHost.Start method successfully. When viewing the process with ProcessExplorer, I see the clr.dll (version 4) being loaded into the virtual address space.
Next, I call ICLRRuntimeInfo:GetInterface to retreive a pointer to the ICorRuntimeHost interface, and use that pointer to call
ICorRuntimeHost:GetDefaultDomain. Then, I call IUnknown:QueryInterface to retreive the DefaultDomain (IID_AppDomain) interface pointer. At this point, mscorlib.dll or one of its variants (mscorlib.ni.dll) is loaded by the CLR into the address space.
What I need now is to enumerate through some of the basic .NET types and methods, to retrieve addresses. And, what I need to do this, and don't have are definitions for the vtables of the interfaces of, for instance, _Assembly which expose the public members of the System.Reflection.Assembly class to unmanaged code. These are huge COM interfaces, and, to execute their methods correctly, one must know the offset of the method (function pointer) from the address of the interface virtual function table.
To actually call these interface methods in assembly you don't even have to prototype the function (although doing so makes your code much more readable and understandable), all you have to is push the appropriate parameters onto the stack, and call the function with the function pointer.
So, finally,...my question: where can I find the interface definition files, for mscorlib COM interfaces like: System.Runtime.InteropServices._Assembly, or, System._AppDomain interface, or, especially, System._Type...???
I've been using the OLE/COM Object Viewer to do this,...assuming that the mscorlib Type Library has the exact same interface definitions as the actual .NET Framework classes, types and methods,...but, I'm crashing my application with (presumably) incorrect parameters or signatures,...

I can't confidently answer your question at all...
However here is what relevant info I found:
1st apparently to call .NET class from COM (or as COM component in your case) you need the mscorlib.tlb, as explained there
How to: Reference .NET Types from COM[^]
and a longer one
Calling a .NET Component from a COM Component[^]
I suspect these article might not help much or are nothing new for you, and you still wonder.. where is this damn mscorlib.tlb?
Well.. it's somewhere in the .NET framework folder:
Open
C:\Windows\Microsoft.NET
And search for mscorlib.tlb, there are a few of them!

As a side note, can you talk about this project of yours?
Looks.. interesting?!
And you might consider loading .NET Core[^] instead of the normal framework?
