Question

im looking for a way to do the following things:

CommandLine

msbuild myProject.csproj /p:MyInfoText

And in my C# Project in the AssemblyInfo.cs I would do:

[assembly: AssemblyInformationalVersion($MyInfoText)]

I tried targets with BeforeBuild option, but nothing worked. Anybody can and want to help?

First of all thx for your comments and answers!

I was looking for a way to set my AssemblyInformationalVersion with a property which I can set over the msbuild cli tools.

I dont want to use any nuggets or third party libaries. So the Community.Tasks are not an option. Obivously I found a solution with this nugget for my problem.

Now to my final solution:

I was looking hows the Community.Task.Nugget is working and built my own solution You can declare inline Tasks in your csproj where you can write C# Code in it.

 <UsingTask TaskName="MyCustomTask" TaskFactory="CodeTaskFactory" 
        AssemblyFile="$(MSBuildToolsPath)\Microsoft.Build.Tasks.v4.0.dll"> //When using .NETCORE use here ...Tasks.Core.dll and change TaskFactory to RoslynTaskFacotry
       <ParameterGroup>
         <MyParam ParameterType="System.String" Required="true" />
       </ParameterGroup>
       <Task>
         <Reference Include="System.Core" />
         <Using Namespace="System" />
         <Code Type="Fragment" Language="cs">
           <![CDATA[
             // My C# Code comes here!
             // You can use your params here with Name like Console.WriteLine(MyParam)
            ]]>
         </Code>
       </Task>
     </UsingTask>

Now you can use it like a normal Task in your .csproj

<Target Name="foo">
 <MyCustomTask MyParamter="Test" />
</Target>

I solved my problem with coding a custom Task which can add/replace the AssemblyInformationalVersion inside the AssemblyInfo.cs before the build.
