Error "There is no application host available for the specified RuntimeIdentifier 'ios-arm64'"

Igor Kravchenko 281

Today I installed .NET 7 SDK 7.0.100-rc.1 from here (don't ask me why) and this ruined my build. I have several errors:

NU1012: Platform version is not present for one or more target frameworks, even though they have specified a platform: net7.0-maccatalyst  
NETSDK1084	There is no application host available for the specified RuntimeIdentifier 'ios-arm64'.	AndriyCo.Tcu.MauiClient	C:\Program Files\dotnet\sdk\7.0.100-rc.1.22431.12\Sdks\Microsoft.NET.Sdk\targets\Microsoft.NET.Sdk.FrameworkReferenceResolution.targets	135

I have tried to repair from installer but no result. I need help =)
Thanks.

Hi @Igor Kravchenko , You said " repair from installer", it means that you have installed Visual Studio 17.4 Preview 2.1, right? .NET MAUI is now available in .NET 7 beginning with release candidate 1 (RC1). It's recommended that you can use Visual Studio 17.4 Preview 2.1 or newer.
You could open csproj file in your project and check if you have replaced net6.0 TFMs with net7.0 (I can see you have replaced net7.0-maccatalyst), then you could delete the bin and obj files, and restart Visual Studio to restore .NET 7 dependencies cleanly.
And you could check if you have defined .NET SDK version in the global.json file. If you always want to use the latest SDK version that is installed on your machine, no global.json file is needed. For more details, you can refer to .NET 7 and .NET MAUI · dotnet/maui Wiki · GitHub

I have created a new sample project and in the error description was

To build this project, the following workloads must be installed: maccatalyst  
To install these workloads, run the following command: dotnet workload restore

I ran that command

dotnet workload restore C:\Users\Igor\source\Workspaces\AndriyCo.Tcu\AndriyCo.Tcu.MauiClient\AndriyCo.Tcu.MauiClient.csproj

and all works fine now. Interesting that suggestion to use that command was in newly created project instead of my default project.
