There are several options to define the assembly information of an .NET Core app in F#:

• .fsproj file
• Directory.Build.props file
• When running dotnet build or dotnet publish: -p:Version=a.b.c.d

The information of the .fsproj file seems to have priority over Directory.Build.props file. You can place the Directory.Build.props file in the project folder or the solution folder.

.fsproj file

<Project Sdk="Microsoft.NET.Sdk">

  <PropertyGroup>
    <OutputType>Exe</OutputType>
    <TargetFramework>netcoreapp3.1</TargetFramework>

    <Version>1.0.0.0</Version>
    <FileVersion>1.0.0.0</FileVersion>
    <Product>MyApp</Product>
    <Copyright>Copyright © 2020 by myself</Copyright>
  </PropertyGroup>

  <ItemGroup>
  ...

Directory.Build.props file

<Project>
  <PropertyGroup>
    <Version>1.0.0.0</Version>
    <FileVersion>1.0.0.0</FileVersion>
    <Product>MyApp</Product>
    <Copyright>Copyright © 2020 by myself</Copyright>
  </PropertyGroup>
</Project>

Check the assembly version

The simple way

• Run: cat MyApp.dll
• Check the last lines. They contain the assembly information

The convenient way

Install the versioninfo tool and run it on the .dll:

• dotnet tool install --global dotnet-versioninfo
• versioninfo MyApp.dll
