NET tool roll forward error experience #38210

JL03-Yue · 2024-01-23T22:50:20Z

This pull request addresses the issue where the installation of a tool with an incompatible runtime results in failure. The proposed changes aim to provide clearer instructions for users encountering this issue and offer alternative solutions for resolution.

Changes made for error message:

Instructions with --allow-roll-forward flag: Included a step-by-step guide for users to install the tool with the --allow-roll-forward flag. The provided command (dotnet tool install --allow-roll-forward footool) is copy/pastable for user convenience.
Added guidance on installing .NET: Provided a link to download and install .NET , which is required by the tool. Users encountering compatibility issues are advised to install the required runtime using the provided link. Note that the given prompt leads to a general .NET downloading page https://aka.ms/dotnet/download/sdk/
Instructions with --force flag: Included instructions for users to install the tool with the --force flag and manually configure it to run. The provided command (dotnet tool install --force footool) allows users to force the installation and provides an alternative approach to resolving compatibility issues.

User experience: When installing a footool with incompatible runtime

Installation failed.

This app wasn't installed because it won't run on your machine. This can be resolved by one of the following:

1. Install with the `--allow-roll-forward` flag, using with the following command.

dotnet tool install -g --allow-roll-forward footool

2. Install .NET {version} with the following link

https://aka.ms/dotnet/download/sdk/

4. Install with `--force` and manually configure the tool to run, using with the following command.

dotnet tool install -g --force footool

Note that the global flag command prompt -g contains based on global or local tools install. Note that the provided prompt for downloading new .NET framework leads to a general .NET downloading page.

+                // RuntimeConfigDetectionResult incompatible
+                // TBD: if include -g in sample command; which version should be included in the install; --force?


Tests should be included for --force and IsRuntimeConfigCompatible functions

It looks like --force was added but maybe not IsRuntimeConfigCompatible.

+            IntPtr parametersPtr = Marshal.AllocHGlobal(Marshal.SizeOf(parameters));
+            Marshal.StructureToPtr(parameters, parametersPtr, false);


The parameters are not used for anything... do we need this?

This still needs to be removed.

+        internal struct hostfxr_initialize_parameters
+        {

This would be invalid if used - the structure must have at least the first size field - it's used effectively as a versioning mechanism. And it MUST be set before calling the initialize function.

This also still needs to be done.

+            var runtimeConfigFilePath = Path.ChangeExtension(executableFilePath.ToString(), ".runtimeconfig.json");
+
+            // Check if the runtimeconfig.json file is compatible with the current runtime


compatible with the current runtime

Just want to call out exactly what this means. The hostfxr_initialize_for_runtime_config is being run in-proc here, so it will check for compatibility with the already loaded runtime.

The current/loaded runtime in this context would be what the SDK command is runnning on.

The SDK chosen is affected by global.json settings and then the runtime is chosen based on the SDK's dotnet.runtimeconfig.json, which specifies the runtime matching the SDK version.

This means current runtime may not be the latest installed runtime.

Actually, I think this is a larger problem. Checking for compatibility with the loaded runtime means checking for frameworks - not just the core runtime. Since dotnet.dll only depends on the core runtime, it will only have that loaded.

Tools could depend on other frameworks like AspNetCore or WindowsDesktop, right? I think that is a test case that should be covered. I expect any tools like that would fail the compatibility check here.

Yes, tool could be depend on other frameworks.

The new hostfxr_resolve_frameworks_for_runtime_config API considers other types of frameworks. We should call that and see if it returns 0.
