  1. Update target frameworks to .NET 10.0 

    - Replace `netcoreapp2.1` and `netcoreapp3.1` targets with `net10.0`.
- Update the test project to target `net462` instead of `net45`.
- Add `global.json` to require the .NET 10 SDK.
- Use system ILAsm on macOS to support osx-arm64 builds, bypassing unavailable .NET Core 2.0 packages.
- Set `LangVersion` to 10.0 and `AnalysisLevel` to 6.0 for DLR projects.
- Guard COM activation tests on non-Windows platforms.
- Update `make.ps1` to default to `net10.0` and auto-detect platform architecture.
- Remove the unavailable nunit myget feed from `NuGet.config`.

  2. Update target frameworks to .NET 10.0 

    - Require .NET 10 SDK for building and update documentation.
- Fix _locale.PreferredEncoding to fallback to UTF-8 when ANSICodePage is 0.
- Fix enum serialization in ClrModule by using the underlying type.
- Fix string formatting in IntOps and LongOps to respect zero precision.
- Use CultureInfo.InvariantCulture for double.TryParse in MarshalOps.
- Resolve method resolution conflicts for BigInteger.IsNegative and IsPositive introduced by new .NET generic math interfaces.
- Catch SystemError in inspect.getdoc.
- Improve Mono tool discovery on macOS in process_util.py.
- Add missing late stage items for packaging in IronPythonConsoleAny.csproj.
- Disable UTF-7 codec tests on modern .NET.
- Force en_US.UTF-8 locale during tests on Unix for consistent decimal separators.
- Update test assertions for SSL, method binding, and enums to match .NET 10 behavior.

  3. Update target frameworks to .NET 10.0 

    Add `net10.0` to project target frameworks and resolve compatibility issues with .NET 10:
- Replace `BinaryFormatter` serialization with `NotSupportedException` on .NET 10+.
- Throw `NotImplementedError` for `thread.interrupt_main` as `Thread.Abort` is unsupported.
- Omit Constrained Execution Region (CER) API usage on .NET 10+.
- Update GC stress tests to use weak references to account for non-deterministic caching.

Secondary behavior, compatibility, and configuration improvements:
- Fix a race condition in the `List` indexer during concurrent modifications.
- Implement a Darwin-specific file locking strategy for SQLite on macOS.
- Discover extension DLLs located beside the entry executable.
- Preserve Unix file permissions when building ZIP packages.
- Replace obsolete `SHA1Managed` with `SHA1.Create()`.
- Ensure complete stream reads in the `array` module.
- Disable NuGet package pruning for legacy inner builds.

  4. Add tools to decompile IronPython cached code 

    This adds a suite of utilities to reconstruct decrypted EAS images and decompile IronPython 2.7 DLRCachedCode assemblies back into readable Python source.

Notable implementation details:
- reconstruct_eas.py mirrors EAS images and drives ILSpy decompilation.
- decompile_ironpython.py acts as a semantic decompiler, using tree-sitter-c-sharp to invert ILSpy C# output into Python expressions, control flow, and generators.
- Metadata extraction and indexing scripts recover scope and dependency information without executing the cached modules.
- Validation scripts and a known-source fixture ensure the recovered Python code compiles correctly under the target interpreter.
