When trying to use the magnifing glasson one of my DataSet
or DataTable
in my .Net Core 3.1 WPF Project I get a System.IO.FileLoadException
with following text:
Could not load file or assembly 'DataSetVisualizer.DebuggeeSide, Version=16.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'. General Exception (0x80131500)
Stack trace:

I narrowed the cause for this problem down to my recently implemented method to load assemblies from subfolders at runtime, which I wrote based on Reza Aghaei's answer on my last question.
In narrowed it down to the subscription on the AppDomain.CurrentDomain.AssemblyResolve
event, but couldn't find a way to solve it yet.
AppDomain.CurrentDomain.AssemblyResolve += (obj, arg) =>
{
var name = $"{new AssemblyName(arg.Name).Name}.dll";
var assemblyFile = referenceFiles.Where(x => x.EndsWith(name))
.FirstOrDefault();
if (assemblyFile != null)
return Assembly.LoadFrom(assemblyFile);
throw new Exception($"'{name}' Not found");
};
It doesn't matter if I am trying to view the DataSet
in one of the loaded assemblies or the startup application.
I would like to keep working with this method to load assemblies at runtime, but since I am working with a lot of DataSets
being able to use the DataSet Visualizer is crucial for me.
Any suggestions?
edit: usage of dataset visualizer during debugging:
Not an elegant solution, but as a workaround to unblock your debugging sessions, add the following to the beginning of the AssemblyResolve
event handler:
#if DEBUG
if (arg.Name.StartsWith("DataSetVisualizer"))
return null;
#endif
