Net4x.Project2015To2017.Migrate2019.Tool

.NET global tool that converts legacy (VS2015-era) MSBuild project files to the modern SDK-style format used by Visual Studio 2019 and later. Part of CsprojToVs2017.

Installation

dotnet tool install --global Net4x.Project2015To2017.Migrate2019.Tool

Requires the .NET 8 runtime. The tool is invoked as dotnet migrate-2019.

To migrate to VS2017 conventions instead, install Net4x.Project2015To2017.Migrate2017.Tool, which provides dotnet migrate-2017 with a few small behavioural differences for older Visual Studio versions.

Quick start

dotnet migrate-2019 wizard "D:\Path\To\My\TestProject.csproj"
dotnet migrate-2019 wizard "D:\Path\To\My\TestProject.sln"
dotnet migrate-2019 wizard .\MyProjectDirectory
dotnet migrate-2019 wizard **\*

The wizard is interactive and walks you through the conversion, offering to create backups before every critical stage.

Paths are optional. With no arguments the tool searches the current directory; if there is exactly one convertible project or solution it uses it, otherwise it tells you why it cannot decide safely.

What it fixes

VS2017 and later handle several things differently. The tool:

  1. Replaces per-file Compile entries with wildcard includes
  2. Rewrites project references in the succinct modern form
  3. Converts packages.config to PackageReference
  4. Folds AssemblyInfo.cs attributes into the project file
  5. Moves the NuGet package definition into the project file
  6. Selects the right project SDK — Microsoft.NET.Sdk.WindowsDesktop for WPF/WinForms, MSBuild.Sdk.Extras for Xamarin and UAP

Commands

Command Description
wizard Interactive conversion wizard (recommended — it runs the others in the right order)
migrate Non-interactive migration, for scripts and advanced users
evaluate Report what migration would do, without changing anything
analyze Run diagnostics against the project files, no conversion

Options

Option Applies to Description
-t\|--target-frameworks <frameworks> migrate, evaluate Override the target frameworks in the output project file
-ft\|--force-transformations <names> migrate Force specific transformations to run regardless of project conversion state
-f\|--force migrate, evaluate, wizard Convert project types otherwise considered unsupported (e.g. Entity Framework, ASP.NET)
-a\|--keep-assembly-info migrate, evaluate, wizard Keep AssemblyInfo.cs instead of folding attributes into the project file
-o\|--old-output-path migrate Do not append the target framework to the output path
-n\|--no-backup migrate Skip creating the Backup directory (useful when the solution is under source control)
-v\|--verbosity <LEVEL> all q[uiet], m[inimal], n[ormal], d[etailed], diag[nostic]
-h\|--help all Show help for the command

Not every option applies to every command — check dotnet migrate-2019 <command> --help.

Repeat an option to pass multiple values:

dotnet migrate-2019 migrate -t net40 -t net45

Migrating from your own code

For programmatic control, use Net4x.Project2015To2017.Migrate2019.Library and Net4x.Project2015To2017.Base directly rather than shelling out to this tool.

  • Net4x.Project2015To2017.Migrate2017.Tool — dotnet migrate-2017, the VS2017 equivalent
  • Net4x.Project2015To2017.Migrate2019.Library — the VS2019 transformation and diagnostic sets
  • Net4x.Project2015To2017.Base — MigrationFacility, the high-level orchestration entry point
  • Net4x.Project2015To2017.Core — project model, readers, writer, transformation and analysis engine
  • Net4x.Project2015To2017.Mcp.Server — the same operations exposed to AI agents over MCP
