Adding Windows as a Targetframework afterwards / retroactively

[maslewandowski]

Hi,

i've developed and deployed a ipad os (ios) app with .net maui 9 and everything works fine.
Now i want to deploy this app also for windows clients.

Sadly i deleted all the platform directories at start of development because i thought that my customer only wants to use it on apple ipads.

So what i did now is:

1. added windows as targetframework (2 approaches: 1st was to add
I tried two approaches:
1st: <TargetFrameworks>net9.0-ios;net9.0-windows</TargetFrameworks>
2nd:

<TargetFrameworks></TargetFrameworks>
<TargetFrameworks Condition="$([MSBuild]::IsOSPlatform('windows'))">$(TargetFrameworks);net9.0-windows10.0.19041.0</TargetFrameworks>

both ended up with some visual studio professional (ide) background tasks that failed in the end.
nuget restore failed
and i get NU1105 error telling me, that there is more than one applicationdisplayversion set. which is definitely not.

search results: only one in this whole project:

2. recreated the platforms/windows directory based on an existing .net maui project.
the directory structure is working but some problems appeared.

finally i am not able to add windows as target.

Is there any documentation or manual that helps me achieve this goal?

thanks and greetings

I can see this in my MAUI .csproj file:

    <ApplicationDisplayVersion>1.0.0</ApplicationDisplayVersion>
    <ApplicationVersion>1</ApplicationVersion>

Perhaps you miss the later one?

If it does not help, it's really helpful to create a new MAUI project and copy Platforms/Windows folder to your project and compare .csproj files by a diff tool.

@maslewandowski How did you fix your issue, if you did?

i did not. i worked around with the creation of a new project and copy and paste actions... sadly.
