System.Private.ServiceModel not found

I've been using a library for opcua and haven't had any problems until now, didn't change anything in dependencies, but suddenly, I get the error during runtime that the System.Private.ServiceModel is not found. When I add a reference to the exact same version as the one that the error message is indicating, it is telling me that there is a conflict:
Severity Code Description Project File Line Suppression State
Error NU1605 Warning as Error: A downgrade of the "System.Private.ServiceModel" package from 4.5.3 to 4.5.1 has been detected. Refer directly from the project to the package to select a different version.
MyProject -> MyProject.Shared -> Opc.UaFx.Advanced 2.41.1 -> System.ServiceModel.Primitives 4.5.3 -> System.Private.ServiceModel (>= 4.5.3)

MyProject -> MyProject.Shared -> Opc.UaFx.Advanced 2.41.1 -> System.ServiceModel.Primitives 4.5.3 -> System.Private.ServiceModel (>= 4.5.3)
I honestly have no idea what the problem is, I've had a similiar problem before with System.IO.Ports, but that somehow dissapeared at some point. When I do a clean build without the reference to System.Private.ServiceModel, I also don't get the dll in the output directory, despite it being referenced by the other package, and if I look at older releases, the dll was always present. This has been bugging me for a whole day and the only workaround is to manually copy the dll or add the dll to the project (which in my opinion is ugly as hell) Hope somebody might know what the problem could be. Thanks in advance.

is this the full error? i think there is supposed to be more text

The only additional thing after is the project files that cause it, basically the same line as MyProject -> ... but with the .csproj suffix

the error does not make sense. it does not show what is downgrading System.Private.ServiceModel to 4.5.1 it is uspposed to show the two different paths to System.Private.ServiceModel that resolve to different versions

Ah, yeah, sorry my bad, didn't see the difference in there

System.Private.ServiceModel (>= 4.5.0.3)
it seems like you meant to write 4.5.3 not 4.5.0.3 yes, the assembly version might be 4.5.0.3. but what matters here is the package version, not the assembly version the package 4.5.3 contains the assembly version 4.5.0.3. they are different for reasons
soziapath
soziapath2mo ago
okay, then at least that is resolved, but the question remains, why I need to add the reference in the first place, since the library has it as dependency
reflectronic
reflectronic2mo ago
i don't know
soziapath
soziapath2mo ago
Okay, I added it as reference with Version 4.5.3, but I still don't get the dll in the output
reflectronic
reflectronic2mo ago
it shows up in my output when i reference Opc.UaFx.Advanced under runtimes/
soziapath
soziapath2mo ago
same for me, but not in the root output directory, which seems to be required? Still get the error unless I copy it manually to the same path as the executable
reflectronic
reflectronic2mo ago
do you not have a ProjectA.deps.json file in your build output
soziapath
soziapath2mo ago
I do have that dependency file and it contains the Dependency

I think that would be too much work to pseudonymize all the names while still keeping it functional^^

Ah, is just replaced the sensitive stuff with bullshit and let chatgpt make it pretty, guess it replaced opcua as well. AdvancedLibrary is opc.uafx.advanced

Honestly, I'm still pretty new to C# in general, never had the time to really understand all the ins and outs, since I had to jump straight into the project... Stack Trace seems to be pretty empty...

reflectronic

ok. well, nothing seems suspicious there it is possible to debug this further but i think it will be easier to try this: delete the reference to System.Private.ServiceModel instead, add a reference to
<PackageReference Include="System.ServiceModel.Primitives" Version="6.0.0" />
<PackageReference Include="System.ServiceModel.Primitives" Version="6.0.0" />
the newer version of the package is put together in a less unconventional way, so whatever is causing this issue might not have a chance to do the wrong thing
soziapath
soziapath2mo ago
Thanks a lot for the help! Will try that now... Still the same error
reflectronic

that System.Private.ServiceModel is not found? that does not make sense. it does not exist with the 6.0.0 version of the package
soziapath
soziapath2mo ago
It still seems to be part of the dependencies in the deps.json, I deleted the build folder, output folder, did a clean and a clean build, still seems to appear in the deps.json
reflectronic
reflectronic2mo ago
it is definitely not part of mine. the word private doesn't show up anywhere
<BaseOutputPath>..\..\..\bin</BaseOutputPath>
just to be clear, the two build outputs do not go into the same folder, right
soziapath
soziapath2mo ago
they do go to the same folder
reflectronic

._. that is entirely wrong tht should never be done it would explain these inexplicable issues, because it just means one build will randomly overwrite the other based on which one happens first

honestly, i think nobdody really had any idea what they were doing. I just recently started working at the company and it's honestly baffling, even my private projects have better structure, testing, etc. But since I'm still pretty new to c#, .net, msbuild etc, I'm not really in for improving things, just wanna finish the current project and then maybe/hopefully have some time for general improvements.

do you have System.ServiceModel.Primitives/6.0.0? if you do not have System.ServiceModel.Primitives/6.0.0, and you are sure you added the right package reference, then are you sure you are looking at the right deps.json file?
