-Subject: [PATCH] Lift System.Memory version
-
-System.Memory version needs to align with the runtime since System.Collections.Immutable is lifted in order to prevent the following situation:
-error NU1605: Detected package downgrade: System.Memory from 4.5.5 to 4.5.4. Reference the package directly from the project to select a different version.  [/repos/tarball-rc1/src/razor-compiler/artifacts/source-build/self/src/razor-compiler.sln]
-error NU1605:  Microsoft.CodeAnalysis.Razor -> Microsoft.CodeAnalysis.CSharp 4.4.0 -> Microsoft.CodeAnalysis.Common 4.4.0 -> System.Collections.Immutable 7.0.0-rc.1.22422.23 -> System.Memory (>= 4.5.5)  [/repos/tarball-rc1/src/razor-compiler/artifacts/source-build/self/src/razor-compiler.sln]
-error NU1605:  Microsoft.CodeAnalysis.Razor -> Microsoft.CodeAnalysis.CSharp 4.4.0 -> Microsoft.CodeAnalysis.Common 4.4.0 -> System.Memory (>= 4.5.4) [/repos/tarball-rc1/src/razor-compiler/artifacts/source-build/self/src/razor-compiler.sln]
