Error in Unity.Tiny.GameSave while building | Tiny ver 0.31.0-preview.26

I've downloaded sample projects for Unity Tiny from here https://github.com/Unity-Technologies/ProjectTinySamples and I've tried to build few of them (2D, 3D, Spaceships) each was built on Desktop target (I've also tried iOS) on Unity version 2020.1.12f1 and 2020.1.10f1 and each time I got the same error in Unity.Tiny.GameSave package code:

Library/PackageCache/com.unity.tiny@0.31.0-preview.24/Unity.Tiny.GameSave/GameSaveSystem.cs(9,37): error CS0122: 'Binding' is inaccessible due to its protection level

The offending line of code is:

using static Unity.Baselib.LowLevel.Binding;

I have not changed anything in the project, no packages were updated, it failed to build as soon as I have downloaded, opened the project and tried to build it. Here is the packages manifest:

I hope the issue is in configuration of the project and someone will be able to point out the probable cause, thanks!

 

I have the same problem

 

Reimport All did not help, the same error appears when I try to build on Mono with Windows x64 target.

After opening one project I noticed that the PackageManagerSettings.asset had differences between what is in the repo and what I have locally:

Does this look helpful abut what may be the problem or is this expected that the url here changes?

 

It did not help with this particular issue indeed.
When I removed the Library directory for the Tiny Kitchen sample, pulled the last commit and opened the project fresh I happened to get this error, which has already appeared before when I was opening the samples, only when opening the project for the first time. It did not appear on every sample project, but every sample project results with the same build error as in my initial description of the problem, so that's probably not the root issue as well. I was running Reimport All in each sample project after opening Unity too.

 

You said you were using
Tiny ver 0.31.0-preview.26
but why the error said it's about Library/PackageCache/com.unity.tiny@0.31.0-preview.24/??

 

Yes, that is exactly right. These are all directories with "tiny" in Library/PackageCache on a freshly (first time )opened sample TinySpaceship

d---- 2020-11-24 12:32 com.unity.tiny.all@0.31.0-preview.26

You can see there are version mismatches, but those are intended as this is how the package.json of com.unity.tiny.all@0.31.0-preview.26 looks like:

I guess this is not an issues as this problem would occur for all users. So far there are few people who have posted on this forum having this same issue and internally in our company we've tried building Project Tiny samples on different machines, OS and Unity versions and we all got the same exact error while building on standalone platform as in my initial message.

 

Correct, I see... Try to update Visual Studio and Windows SDK?

 

I'm having the same error, won't build,
"Library\PackageCache\com.unity.tiny@0.31.0-preview.24\Unity.Tiny.GameSave\GameSaveSystem.cs(9,37): error CS0122: 'Binding' is inaccessible due to its protection level"

 

Just wanted to put in here so the reach is known. I am getting the same error when trying to build for both PC, Mac, Linux as well as android.
