QUESTION
I'm trying to consume Azure DevOps .NET API, specifically the Git client, from Powershell 5.1. There is a copy of all client libraries under C:\Program Files\Microsoft Visual Studio\2022\Enterprise\Common7\IDE\CommonExtensions\Microsoft\TeamFoundation\Team Explorer.
So first I tried that in a C# program:
...ANSWER
Answered 2022-Apr-01 at 14:35Preamble: the dependency resolution in the C# program was not picking up v12 where v9/6 was requested automagically; it was only doing so because the config file of the compiled program was telling it so, and that only happened once and because Newtonsoft v12 was being referenced in the project. Thanks to @n0rd for pointing that out. Resolving strongly named dependent assemblies to a higher major version is not a default behavior in .NET 4.5-8.
Modifying the config of Powershell to achieve the same might be possible, but I didn't go there. The original piece that needed this logic will be eventually running on servers that I don't control, so the less administrative overhead, the better. Now, for the working answer.
You can provide a resolve handler in Powershell 5 after all, telling .NET to use the loaded version of Newtonsoft in lieu of any other one. It goes like this:

I've made a little test for my project today - The goal: Implement .jar files into a C# project as a .dll. My current .java / .jar file looks like the following.
ANSWER
Answered 2022-Mar-03 at 15:48First of all, you are using a class as a namespace, and that is probably not correct. Your method call should probably look something like this:

I'm sorry if this has been asked before, but I don't even know what to search for to find an answer.
I'm fairly experienced in .net/c# etc., however, I have come across something I don't understand how works.
I'm working on a third party library where I do not have access to the source.
My question is: How is this function able to get the whole data in the array when only the first value is being passed?

Answered 2021-Dec-18 at 14:40The PublicKeyToken is null, which mean the DLL is not signed with a strong name. You need to sign the Dll and then put it to GAC, please refer the MSDN article here, the article also tells you how to sign it in VS:
QUESTION
ILSpy can decompile assemblies. Can it decompile a delegate? I would imagine a CSharpDecompiler constructor overload accepting a Func or an Action as an argument instead of a "string fileName". Is it technically feasible, are there any future plans to support this? Any suggested work-arounds?
Example of what I had in mind....
...ANSWER
Answered 2021-Dec-16 at 09:46An official ILSpy member has answered in the project's discussion section:
"It's not possible, because the decompiler requires a full PE image containing IL code and .NET metadata tables"
QUESTION
I'm have some .NET exes built with the single file option (https://docs.microsoft.com/en-us/dotnet/core/deploying/single-file) and I need to use a disassembler on them, but none of the disassembly tools (e.g. dnspy, ilspy, ildasm, etc.) work since these are actually native binaries with .NET assembly embedded in them, as explained in the Microsoft docs.
E.g., trying ildasm on these binaries outputs error: 'example.exe' has no valid CLR header and cannot be disassembled
How can I extract the .NET dlls from these single file exes so that I can disassemble them? Or is there any other way to disassemble these .NET single file exes?
...ANSWER
Answered 2021-Nov-16 at 17:38ILSpy 7.0 supports .NET 5 single-file bundles.
ILSpy 7.1 adds support for .NET 6 bundles (added compression support).
ILSpy 7.2 also allows saving the embedded .dlls ("Extract package entry" in context menu).

QUESTION
I'm trying to implement my own async method builder for a custom awaitable type. My awaitable type is just a struct containing a ValueTask.
The problem is my asynchronous method builder only works when it's a class or compiled in Debug mode, not a struct and in Release mode.
Here's a minimal, reproducible example. You have to copy this code into a new console project on your local PC and run it in Release mode; .NET Fiddle apparently runs snippets in Debug mode. And of course this requires .Net 5+: https://dotnetfiddle.net/S6F9Hd
This code completes successfully when CustomAwaitableAsyncMethodBuilder is a class or it is compiled in Debug mode. But it hangs and fails to complete otherwise:
ANSWER
Answered 2021-Sep-30 at 19:46Found it! If you use ILSpy to disassemble the .dll compiled from the question's code (use the .NET Fiddle link and follow the question's instructions), and then turn ILSpy's language version down to C# 4 (which was the version before async/await was introduced), then you'll see that this is how the GetValueAsync method is implemented:

I have a dump of an executable file (Runtime: v2.0.50727). It works well without any mistakes. I could load it to DnSpy to debug or to ILSpy. Both of them tells that all references successfully resolved.
However, I can't load it using this code:
...ANSWER
Answered 2021-Jul-26 at 13:47The .bin file you created tracks back to COFF, which .NET 2.0 runtime uses. You can also use dumpbin, to get a .bin file. The documentation states
The Microsoft COFF Binary File Dumper (DUMPBIN.EXE) displays information about Common Object File Format (COFF) binary files.
So, to properly load that, you will need to use Assembly.Load(byte[], ...). That documentation states that its parameter accepts a raw COFF array of bytes:
A byte array that is a COFF-based image containing an emitted assembly.
This part from the above source may also be relevant to you
Reflecting on C++ executable files might throw a BadImageFormatException. This is most likely caused by the C++ compiler stripping the relocation addresses or the
.relocsection from your executable file. To preserve the.relocaddress for your C++ executable file, specify/fixed:nowhen you are linking.

Install ILSpy
Clone the ILSpy repository using git.
Execute git submodule update --init --recursive to download the ILSpy-Tests submodule (used by some test cases).
Install Visual Studio (documented version: 16.9). You can install the necessary components in one of 3 ways: Follow Microsoft's instructions for importing a configuration, and import the .vsconfig file located at the root of the solution. Alternatively, you can open the ILSpy solution (ILSpy.sln) and Visual Studio will prompt you to install the missing components. Finally, you can manually install the necessary components via the Visual Studio Installer. The workloads/components are as follows: Workload ".NET Desktop Development". This workload includes the .NET Framework 4.8 SDK and the .NET Framework 4.7.2 targeting pack, as well as the .NET 6.0 SDK (ILSpy.csproj targets .NET 4.7.2, and ILSpy.sln uses SDK-style projects). Note: The optional components of this workload are not required for ILSpy Workload "Visual Studio extension development" (ILSpy.sln contains a VS extension project) Note: The optional components of this workload are not required for ILSpy Individual Component "MSVC v142 - VS 2019 C++ x64/x86 build tools (v14.23)" (or similar) The VC++ toolset is optional; if present it is used for editbin.exe to modify the stack size used by ILSpy.exe from 1MB to 16MB, because the decompiler makes heavy use of recursion, where small stack sizes lead to problems in very complex methods. Open ILSpy.sln in Visual Studio. NuGet package restore will automatically download further dependencies Run project "ILSpy" for the ILSpy UI Use the Visual Studio "Test Explorer" to see/run the tests If you are only interested in a specific subset of ILSpy, you can also use ILSpy.Wpf.slnf: for the ILSpy WPF frontend ILSpy.XPlat.slnf: for the cross-platform CLI or PowerShell cmdlets ILSpy.AddIn.slnf: for the Visual Studio plugin
Make sure .NET 6.0 SDK is installed.
Make sure PowerShell is installed (formerly known as PowerShell Core)
Clone the repository using git.
Execute git submodule update --init --recursive to download the ILSpy-Tests submodule (used by some test cases).
Use dotnet build ILSpy.XPlat.slnf to build the non-Windows flavors of ILSpy (.NET Core Global Tool and PowerShell Core).
