The code in `AssemblyLoadContext.dll` doesn't need to be in a separate DLL anymore.
S.M.A.dll depends on `AssemblyLoadContext.dll`, so keeping that code out of S.M.A.dll doesn't help make S.M.A smaller size or less dependent. So the code in `AssemblyLoadContext.dll` is moved to `S.M.A.dll` and then we remove `AssemblyLoadContext.dll`.
The changes are:
- Move `CorePsAssemblyLoadContext.cs` to `src\S.M.A\CoreCLR\`
- Update `CorePsAssemblyLoadContext.cs` to get the test took moved to `Utils.InternalTestHooks` and update tests
- Update `build.psm1` and `.csproj` accrodingly
- Update `pwrshcommon.cpp` to remove `AssemblyLoadContext.dll` from the TPA list.
- `S.M.A.AssemblyExtensions` is removed as `PackageManagement` has finished their move to .NET Core 2.0. (I will work with Bryan to get the latest version uploaded to powershell-core)
Make `System.Management.Automation references` to package `System.Security.Permissions`, which brings back `SecurityZone` and `System.Security.Policy.Zone`.
`AssemblyVersion` and `FileVersion` are now inferred from the `Version` property, which is inferred by `VersionPrefix`. So now both `AssemblyVersion` and `FileVersion` are 6.0.0.0 for each of PowerShell assemblies, and the `ProductVersion` and `InformationalVersion` are 6.0.0.
* Update assemblies versions by MSBuild and create a new PowerShellAssembly.props file to consolidate properties.
* Move import on first place
* Move to "6.0.0-beta.3"
Use 2.0 CLI/SDK of version `2.0.0-preview1-005952` to keep in sync with the .NET Core 2.0 //Build dogfood instructions. The version of `Microsoft.NetCore.App` in use is `2.0.0-preview1-002106-00`.
This change moves powershell to .NET Core 2.0. Major changes are:
1. PowerShell assemblies are now targeting `netcoreapp2.0`. We are using `microsoft.netcore.app-2.0.0-preview1-001913-00`, which is from dotnet-core build 4/4/17. We cannot target `netstandard2.0` because the packages `System.Reflection.Emit` and `System.Reflection.Emit.Lightweight`, which are needed for powershell class, cannot be referenced when targeting `netstandard2.0`.
2. Refactor code to remove most CLR stub types and extension types.
3. Update build scripts to enable CI builds. The `-cache` section is specified to depend on `appveyor.yml`, so the cache will be invalidated if `appveyor.yml` is changed.
4. Ship `netcoreapp` reference assemblies with powershell to fix the issues in `Add-Type` (#2764). By default `Add-Type` will reference all those reference assemblies when compiling C# code. If `-ReferenceAssembly` is specified, then we search reference assemblies first, then the framework runtime assemblies, and lastly the loaded assemblies (possibly a third-party one that was already loaded).
5. `dotnet publish` generates executable on Unix platforms, but doesn't set "x" permission and thus it cannot execute. Currently, the "x" permission is set in the build script, `dotnet/cli` issue [#6286](https://github.com/dotnet/cli/issues/6286) is tracking this.
6. Replace the use of some APIs with the ones that take `SecureString`.
7. osx.10.12 is required to update to `netcoreapp2.0` because `dotnet-cli` 2.0.0-preview only works on osx.10.12.
8. Add dependency to `System.ValueTuple` to work around a ambiguous type identity issue in coreclr. The issue is tracked by `dotnet/corefx` [#17797](https://github.com/dotnet/corefx/issues/17797). When moving to newer version of `netcoreapp2.0`, we need to verify if this dependency is still needed.
Based on the conclusion in discussion #3248, this PR fix "OEM" and "Default" encoding in powershell.
1. OEM -- We need an internal fix because .Net Core has no "OEM" encoding.
The fix gives the following PowerShell Core behavior on "OEM" encoding:
- on Windows - as Windows PowerShell based on GetOEMCP() and legacy encodings (System.Text.Encoding.CodePages)
- on Unix - the same as default encoding in PowerShell Core
2. Default -- We need internal fix because CoreFX `Encoding.default` for all platforms is UTF8.
Until we complete the `Encoding RFC` we should restore behavior as in Windows PowerShell.
The fix gives the following PowerShell Core behavior on "Default" encoding:
- on Windows - as Windows PowerShell based on GetACP() and legacy encodings (System.Text.Encoding.CodePages)
- on Unix - UTF-8 without BOM (We are expecting that the same will be [in CoreFX](https://github.com/dotnet/coreclr/issues/10643))
- FullCLR build is disabled in this change.
- FullCLR build related functionalities in `build.psm1` and `AppVeyor.psm1` are disabled. They are not cleaned up from `build.psm1` and `AppVeyor.psm1` yet. We need to adopt .NET Core 2.0 to verify the portable module concept, and if that works well, we will remove the Windows PowerShell source code and clean up our scripts.
- `dnxcore50` and `portable-net5+win8` target framework monikers are removed.
- Dependency on `Microsoft.NETCore.Portable.Compatibility` is removed. It's not necessary, but it may come back when we work on supporting the `portable module`. Its necessity can be reviewed at that time.
- I didn't spend the time to try building powershell in Visual Studio 2017. We should have a separate issue for that. It's tracked by #3400
The `TypeCatalogParser` project is replaced by a MSBuild target to gather the dependency information.
Due to .NET Core SDK issue [#1021](https://github.com/dotnet/sdk/issues/1021), our meta-package project `Microsoft.PowerShell.SDK` starts to generate an empty assembly during the build and that results in an empty assembly `Microsoft.PowerShell.SDK.dll` appear in `publish` folder and in `.deps.json` file. We cannot simply remove the assembly because it's now part of the TPA, and removing it will cause powershell to crash at startup. We have to live with this empty assembly until that .NET Core SDK issue is fixed. It's tracked by #3401.
