Camlex.Client 5.0 released: support for .NET 5.0 and .NETStandard 2.0 target frameworks

Good news for Sharepoint developers who use Camlex library: today new version of Camlex.Client 5.0.0 has been released. In this version native support for .NET 5.0 and .NET Standard 2.0 target frameworks was added. .NET Framework 4.5 is also still there for backward compatibility.

With this new version you may use Camlex.Client in your .NET 5.0 or .NET Core 3.1/2.1 in native mode. I.e. there won't be warning anymore that Camlex is referenced using .NET Framework compatibility mode. Each Camlex.Client nuget package now has assemblies for 3 target frameworks:

• .NET Framework 4.5
• .NET Standard 2.0
• .NET 5.0

which should cover most of development needs. The following table shows examples which application will use which Camlex.Client version depending on its target framework:

App's target framework	Camlex.Client target framework
.NET Framework 4.5	.NET Framework 4.5
.NET Framework 4.6.1	.NET Framework 4.5
.NET Framework 4.7.2	.NET Framework 4.5
.NET Core 2.1	.NET Standard 2.0
.NET Core 3.1	.NET Standard 2.0
.NET 5.0	.NET 5.0

All Camlex.Client nuget packages has been updated with this change:

• Camlex.Client.dll for SP Online
• Camlex.Client.2013 for SP2013 
• Camlex.Client.2016 for SP2013
• Camlex.Client.2019 for SP2013
  

Method not found error in UnifiedGroupsUtility.ListUnifiedGroups() when use PnP.Framework 1.6.0 with newer version of Microsoft.Graph

Today I've faced with interesting problem: in our .Net Framework 4.7.2 project we use PnP.Framework 1.6.0 (latest stable release currently) which was built with Microsoft.Graph 3.33.0. Then I updated Microsoft.Graph to the latest 4.3.0 version and after that UnifiedGroupsUtility.ListUnifiedGroups() method from PnP.Framework started to throw the following error:

Method not found: 'System.Threading.Tasks.Task`1<Microsoft.Graph.IGraphServiceGroupsCollectionPage> Microsoft.Graph.IGraphServiceGroupsCollectionRequest.GetAsync()'.

When I analyzed the error I found the following: Microsoft.Graph 3.33.0 contains IGraphServiceGroupsCollectionPage interface which has the following method:

In Microsoft.Graph 4.3.0 signature of this method has been changed: cancellationToken became optional parameter:

As result we got Method not found error in runtime. Interesting that app.config had binding redirect for Microsoft.Graph assembly but it didn't help in this case:

<dependentAssembly>
  <assemblyIdentity name="Microsoft.Graph" publicKeyToken="31bf3856ad364e35" culture="neutral" />
  <bindingRedirect oldVersion="0.0.0.0-4.3.0.0" newVersion="4.3.0.0" />
</dependentAssembly>

Also interesting that the same code works properly in project which targets .NET Core 3.1.

For .Net Framework project workaround was to copy code of UnifiedGroupsUtility.ListUnifiedGroups() from PnP.Framework to our project (fortunately it is open source) and then call this copied version instead of version from PnP.Framework. When new version of PnP.Framework will be released which will use newer version of Microsoft.Graph we may revert this change back.
