Value cannot be null (Parameter 'key')

[kfrancis]

Trying to snitch on a .NET 4.8 solution, which it looks like it's possible, but I'm getting the following:

C:\Projects\SuperAwesomeProject>snitch SuperAwesomeProject.sln --tfm net48

Analyzing SuperAwesomeProject.sln
Analyzing SuperAwesomeProject (net48)...
Error: Value cannot be null. (Parameter 'key')

Snitch doesn't seem to have a verbose mode to give me some more information, so there's not much I can do here.

Based on the code, it looks like it's because there are non-"package references" projects in use.

I am getting the same. What is meant by "non-"package references" projects". Is it a line like this?

<ProjectReference Include="..\Other.Folder\Other.csproj" />

or is it the

  <Reference Include="System.Web" />

What is the recommended fix? Neither can be simply deleted.
It would be nicer if the error message reported which file and line that it failed on.

I am getting the same. What is meant by "non-"package references" projects".

I mean projects that use a packages.config file instead of having the references within the project file itself.

[anthony-steele-cko]

Ah. I have no packages.config file references in the .csproj that I am attempting to run snitch on, or any project upstream of it. They do exist elsewhere in the solution, but this should not be relevant as it's not part of the dependency tree being analysed.
