AssemblyDescriptor InitInstance exception

[I-Vladimir]

Hi All,
My application dynamically loads multiple assemblies located in subfolders and each assembly can have FastReport references. I understand the best option is to drop FastReport dlls in exe folder or GAC, but since each module created individually we can get a potential issue with different assembly versions etc, I decided to deploy FastReport assemblies with each module and FastReport assemblies are in subfolders.
An issue I got when a new report assembly created in AssemblyDescriptor InitInstance when a call from FastReport.dll cannot find it. I managed to get it resolved adding an extra ResolveEventHandler.

Hello!

Thank you for your request, it is very important for us!

Could you please let us know if this problem is reproduced on the current version of FastReport Open Source or if you are using FastReport.Net.Demo?

Best regards,
Bogdan

Hello,
Using FastReport Open Source 2024.2.0
My change to get it working
`private void CreateInstance(object reportScript) {
AppDomain currentDomain = AppDomain.CurrentDomain;
try {
currentDomain.AssemblyResolve += new ResolveEventHandler(ResolveEventHandler);
InitInstance(reportScript);
}
finally {
currentDomain.AssemblyResolve -= new ResolveEventHandler(ResolveEventHandler);
}
}

private Assembly ResolveEventHandler(object sender, ResolveEventArgs args) {
Assembly assembly = null;
string dllName = new AssemblyName(args.Name).Name + ".dll";

if (dllName.IndexOf("FastReport",StringComparison.InvariantCultureIgnoreCase) == 0) {
string dll = Path.Combine(this.currentFolder, dllName);
if (File.Exists(dll)) {
assembly = Assembly.LoadFrom(dll);
}
}
return assembly;
}`
