## PR Context
Because `PowerShellGet` does not support publishing/saving module on a per platform basis (see [this](https://github.com/PowerShell/PowerShellGet/issues/273) issue), PowerShell currently also ships the fullclr binaries of `PackageManagement`, which it does not need. Therefore removing it to minimise the package size, this saves 1.19 MB.
Major changes are as follows:
- Avoid `SecuritySupport.IsProductBinary` and unnecessary AMSI/suspicious code scan at startup time
- Update `CompiledScriptBlockData.IsProductCode` to avoid unnecessary calls to `IsProductBinary`, which attempts to retrieve catalog signature of the target file.
- Update `PerformSecurityChecks` to skip AMSI and suspicious code scan for the `.psd1` file that contains a safe `HashtableAst` only.
- Use customized `ReadOnlyBag` instead of `ImmutableHashSet` so that we can avoid loading the `System.Collections.Immutable.dll` completely.
- Replace `SHA1` with `CRC32` when generating module analysis cache file name
- This remove the loading of `System.Security.Cryptography.Algorithms.dll` at startup
- Move `ConvertFrom-SddlString` to C# to remove the `Utility.psm1` file.
- Crossgen `Microsoft.ApplicationInsights.dll` and enable tiered compilation
- Even pwsh with crossgen assemblies spends a lot time in jitting at the startup, about `191.6ms` comparing with `24.7ms` for Windows PowerShell.
- Jitting `Microsoft.ApplicationInsights.dll` takes about `51.6ms`.
- By crossgen `Microsoft.ApplicationInsights.dll` and enable tiered compilation, the jitting time drops to about `98.9ms`.
Since we don't explicitly set the window title, it just shows the path to `pwsh.exe`. Fix is to use the `-Command` parameter to set the window title.
Fix#8163
Guidance is that we can just have the major version at the top "PowerShell 6" and not worry about updating the minor version with each release. The change is on line 230. Word made the other changes to the RTF.
The variable was set to empty (meaning to delete the variable) in the non-preview case and the build fails.
The fix avoids setting the variable to empty
Fixes underlying problem of #3341. Related: #2881
When multiple versions (e.g. RTM and preview) of PowerShell are installed via the MSI and one is being uninstalled, then the start menu shortcut does not get removed due to the shortcut component being not unique per version. This also applies to an upgrade scenario. Therefore use an auto-generated Guid (`*`)
Remove code from build.psm1 that save the modules to a versioned folder. For servicing reasons after release it is preferred and easier to not have the versioned folder so that we can directly replace modules that need to be serviced (MSI specifically makes it difficult to service a module if the folder path changes).
- `ConvertFrom-Markdown` is used for converting a markdown document or string to a MarkdownInfo object. It can optionally return an HTML or a VT100 encoded string in addition to an AST of the markdown document.
- `Show-Markdown` is used to either display the VT100 encoded string on the console or redirect the HTML string to the browser.
- `Set/Get-MarkdownOption` cmdlets are used to view or set markdown rendering options.
* update to latest package references
* update runtime framework
* update sdk
* automatically read NuGet package dependency info from csproj, where version info is fully qualified
* update file.wxs
To support PowerShell modules built with .NET Windows Compatibility Pack, we decided that it was best to ship the WCP assemblies with PS Core. This also adds many new .NET APIs be default while only adding ~3.5 MB additional disk footprint (to a ~137 MB install currently).
Also update the build to adopt the official .NET Core 2.1.
* Build Update
- Change `TargetFramework` to `netcoreapp2.1` and removed unnecessary `RuntimeFrameworkVersion` from `PowerShell.Common.props`
- Update dotnet SDK to 2.1.300-rc1-008662
- Update `TypeGen` target in `Build.psm1` to work with 2.1
- Rename macOS runtime to `osx-x64` as the old build logic expects 10.12 and breaks running on 10.13 system.
- Remove `PackageReference` to `System.Memory` as it's part of dotnetcore 2.1
- Update search for `crossgen` executable to find the matching version
* Test Update
- Update test tools `WebListener` to latest `asp.net core`
- Marked `AuthHeader Redirect` tests as `Pending` due to change in CoreFX
Fixes#6590 by adding registry keys to support the existing explorer context menu also when being inside a library folder. It follows the existing pattern that was already applied to special cases such as drives, Desktop, etc.
Manually Tested on Win 10 1709
Thanks to @mklement0 for triaging the issue and already researching the required registry key (he should also be included in the release notes)
- Can compile a source from strings (TypeDefinition and MemberDefinition).
- Can compile from files.
- Can compile only to a file (without loading the produced assembly).
- Do not recompile and don't reload if the sources have not changed.
- Implement `-IgnoreWarnings` to not treat warnings as errors. By default, the cmdlet considers warnings as errors.
- Add VisualBasic support.
- Add new `-CompilerOptions` parameter to allow setting Roslyn command line parameters including:
- Parser options.
- Compile options.
- Emit options.
**ATTENTION:** The `CompilerOptions` can be specified along with other options like `-OutputAssembly`, `-Language` and `-IgnoreWarnings`. The explicit setting parameters will take precedence over the same settings specified in `-CompileOptions`.
See docs about the compiler options:
https://github.com/dotnet/roslyn/blob/master/docs/compilers/CSharp/CommandLine.mdhttps://github.com/dotnet/roslyn/blob/master/docs/compilers/Visual%20Basic/CommandLine.md
**ATTENTION:** `-OutputType` default is `Library`. If `-OutputType` is absent the `-OutputType` default overlaps a value in `CompileOptions`. In other words output type ("target" ot "t" in command line) is always ignored in `CompileOptions`. We have to use `-OutputType` to set an output type.
Since a PR added support to opt out of telemetry via an environment variable, we can remove the,
always intended to be a temporary, solution of deleting a file to opt out of telemetry since the
environment variable can be defined at the system level and exist before even installing PowerShell Core.
Because the variable is defined as opt out, a value of true, yes, or 1 means no telemetry is sent.
* In cases where the header spans multiple rows, need to correctly calculate whitespace and trim appropriately
* Use System.Span<int> and C# 7.2 language in SMA
* Added new ref assemblies to Files.wxs
refactor tests to remove similar xml content
added single column test case
- Implementation of PowerShell/PowerShell-RFC#115 (If anything changes in the RFC, we will treat it as a bug, and fix it later)
- Update registry and directory paths to use 6 for the version for stable and 6-preview for a preview release
- Add checkbox to set path
- default checkbox to off for preview builds and on for stable builds
