It's marked as not available in single file apps.
Call the underlying get_code_base icall.

Fixes #54835

Is this an actual fix? What does it return for single-file like targets?

In Mono we have two names associated with an assembly. It's "filename" which corresponds to Assembly.Location which is NULL for single-file targets like WebAssembly. And "name" which is derived from the name that the assembly was called in the bundle which is returned for Assembly.CodeBase.

So yea this is the actual fix - the issue is that the CodeBase public getter is tagged as not available in single-file. But get_code_base is not. And it returns a reasonable value. So we use it directly.

Yeah and I don't think that's correct. The value is exposed via https://github.com/dotnet/runtime/blob/main/src/libraries/System.Private.CoreLib/src/System/Reflection/AssemblyName.cs#L63 which says that the values should be empty string (null value effectively)

Thanks. Switched to using MonoImage:filename which will be null for bundles

For bundled asssemblies in single file scenarios, RuntimeAssembly.CodeBase will
be null, matching CoreCLR.

Ok, so now wasm is failing a codebase test in src/libraries/System.Reflection/tests/AssemblyTests.cs because we now return null for the codebase here.

        [Fact]
        public void CodeBase()
        {
            Assert.NotEmpty(Helpers.ExecutingAssembly.CodeBase);
        }

How does this test pass on CoreCLR single file? or is it skipped somehow? @eerhardt

I don't believe the test is executed on CoreCLR single file. Honestly, I don't think any of our library tests are executed under CoreCLR single file.

I believe that is controlled by the following switch -> https://github.com/dotnet/runtime/blob/main/src/libraries/tests.proj#L329
We only tests single file in System.Collections.Tests.csproj and System.IO.IsolatedStorage.Tests.csproj but could be enabled in other projects

I believe there is a single-file like PlatformDetection property.

I think System.Reflection would be a very useful addition to the list.
