Missed dependency?

[davidehnis]

Greetings! It looks like you may have missed a dependency. I had to install package "System.Reflection.TypeExtensions" to get it to work. Installing this resolved exception and it all works like a charm.

Interesting - what exact error were you seeing (at run time or build time?) and what was the target of the consuming application? It's entirely possible I need to adjust the dependencies for some set of consumers based on their target, especially if they're .NET Framework apps.

Happened to my as well while running console application targeting net472.

The code:

var manager = new AnalyzerManager();
var analyzer = manager.GetProject(projectPath);
var results = analyzer.Build(); // throws here

The exception info:

System.IO.FileNotFoundException
  HResult=0x80070002
  Message=Could not load file or assembly 'System.Reflection.TypeExtensions, Version=4.1.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The system cannot find the file specified.

I added System.Reflection.TypeExtensions as a direct dependency to the next version (it was already coming in via transitive dependencies). Hopefully that resolves the issue - I'll close it out but please let me know if the direct package reference is still needed after upgrading to 2.3.1.

Hi @TriEdgeAI - what version of Buildalyzer is this (the latest?), what version of .NET Core (or Framework) is the app running on, and what’s the target of the project being compiled? That’ll help me get to the bottom of why you might be seeing this. Thanks!

Is this useful?

[vladimir-angelov-1337]

I'm getting this

NU1605: Detected package downgrade: System.Reflection.TypeExtensions from 4.6.0 to 4.1.0. Reference the package directly from the project to select a different version. 
 HTMLX.VisualStudio -> Buildalyzer 2.6.0 -> System.Reflection.TypeExtensions (>= 4.6.0) 
 HTMLX.VisualStudio -> System.Reflection.TypeExtensions (>= 4.1.0)

When I tried referencing 4.1.0 manually as a NuGet package.

Very useful, thanks. I have an idea what the problem might be - I’ll check it out tomorrow and see if I can replicate/fix. Stay tuned.

I'm pretty sure this was fixed a while ago so I'm going to assume this issue is either resolved or no longer relevant. Please comment or open a new issue if that's incorrect and you're still having trouble.
