base on Source generator to add D/Invoke and indirect syscall methods to a C# project. # CsWhispers Source generator to add D/Invoke and indirect syscall methods to a C# project. ## Quick Start Add the latest NuGet package to your project and allow unsafe code. ```xml <Project Sdk="Microsoft.NET.Sdk"> <PropertyGroup> <OutputType>Exe</OutputType> <TargetFramework>net481</TargetFramework> <ImplicitUsings>enable</ImplicitUsings> <Nullable>enable</Nullable> <LangVersion>12</LangVersion> </PropertyGroup> <!-- CsWhispers package --> <ItemGroup> <PackageReference Include="CsWhispers" Version="0.0.3" /> </ItemGroup> <!-- Allow unsafe code --> <PropertyGroup Condition=" '$(Configuration)' == 'Debug' "> <AllowUnsafeBlocks>true</AllowUnsafeBlocks> </PropertyGroup> <PropertyGroup Condition=" '$(Configuration)' == 'Release' "> <AllowUnsafeBlocks>true</AllowUnsafeBlocks> </PropertyGroup> </Project> ``` Create a file in your project called `CsWhispers.txt` and set its build action properties to `AdditionalFiles`. ```xml <ItemGroup> <None Remove="CsWhispers.txt" /> <AdditionalFiles Include="CsWhispers.txt" /> </ItemGroup> ``` Add each NT API and any supporting structs/enums that you want to be included in your project. Each must be on its own line, for example: ```text NtOpenProcess HANDLE NTSTATUS CLIENT_ID UNICODE_STRING OBJECT_ATTRIBUTES PWSTR PCWSTR ``` **See the project Wiki for a full list of supported APIs.** Global namespaces are automatically added to allow for clean code. ```c# public static unsafe void Main() { // use self as example using var self = Process.GetCurrentProcess(); HANDLE hProcess; OBJECT_ATTRIBUTES oa; CLIENT_ID cid = new() { UniqueProcess = new HANDLE((IntPtr)self.Id) }; var status = NtOpenProcess( &hProcess, PROCESS_ALL_ACCESS, &oa, &cid); Console.WriteLine("Status: {0}", status.SeverityCode); Console.WriteLine("HANDLE: 0x{0:X}", hProcess.Value.ToInt64()); } ``` ## D/Invoke CsWhispers includes a minimalised version of D/Invoke, so you may also call `Generic.GetLibraryAddress`, `Generic.DynamicFunctionInvoke`, etc. ## Extending All of the generated code goes into a partial `CsWhispers.Syscalls` class, which you can extend to add your own APIs. For example, create `MyAPIs.cs` and add: ```c# namespace CsWhispers; public static partial class Syscalls { public static NTSTATUS NtCreateThreadEx() { // whatever return new NTSTATUS(0); } } ``` This can then be called in your main code without having to add any additional using statements. ```c# namespace ConsoleApp1; internal static class Program { public static void Main() { var status = NtCreateThreadEx(); } } ``` ## TODO - Add 32-bit support. - Randomise API hashes on each build. - Add additional configuration options to choose between direct and indirect syscalls. - Implicitly add structs/enums for APIs without having to declare them in `CsWhispers.txt`. ## Acknowledgements This project was inspired by the previous versions of SysWhipsers and SharpWhispers in particular.
