How to switch to NET6?

[MikeKry]

After updating to NET6 packages, Orchard fails to start.

Is there some action we should do after updating packages?

[hishamco]

Do you have .NET Core 6 installed?

Are you using source or NuGet packages?

[MikeKry]

@hishamco

Yes, I have .NET 6 installed and I am using nugets 1.3.0-preview-16704

It also seems that it works under production env. (ASPNETCORE_ENVIRONMENT) just not in development

[hishamco]

Strange!! please wait for others to reply, I didn't used the latest NuGet packages.

May be it's a caching issue

[MikeKry]

And there was no change in project other than updating nugets & updating target framework of project to net6.0

@giannik @hishamco

seems that this could be another issue, we do not have RazorRuntimeCompilation set in csproj

this is csproj def:

[MikeKry]

Hm, it seems it is caused by "PreserveCompilationReferences", which could be related to RazorRuntimeCompilation

[MikeKry]

@hishamco
If it is the problem and should not be used - documentation should be updated https://github.com/OrchardCMS/OrchardCore/blob/2f3b86545f87baad359622f85c19c5b7b1cf6c9e/src/docs/guides/decoupled-cms/README.md

Yes PreserveCompilationReferences is no more used

OrchardCore/src/OrchardCore.Cms.Web/OrchardCore.Cms.Web.csproj

Lines 8 to 14 in 1d4f283

	<PropertyGroup>
	<TargetFrameworks>$(CommonTargetFrameworks)</TargetFrameworks>
	<TreatWarningsAsErrors>true</TreatWarningsAsErrors>
	<WarningsNotAsErrors>612,618</WarningsNotAsErrors>
	<AspNetCoreHostingModel>InProcess</AspNetCoreHostingModel>
	<RazorRuntimeCompilation>false</RazorRuntimeCompilation>
	</PropertyGroup>

OrchardCore/src/OrchardCore.Cms.Web/OrchardCore.Cms.Web.csproj

Lines 26 to 28 in 1d4f283

	<ItemGroup>
	<PackageReference Include="Microsoft.AspNetCore.Mvc.Razor.RuntimeCompilation" Condition="'$(RazorRuntimeCompilation)' == 'true'" />
	</ItemGroup>

@jtkech so should I create task to fix the guide for decoupled cms?

[jtkech]

Yes, would be fine to create a PR updating the related doc, thanks

My experience is that the runtime compilation is not playing well with .NET6.0. and IMHO just disable it

[jtkech]

Anyway, don't use anymore PreserveCompilationReferences ;)
