This occurs when dynamically loading an assembly that references the Stimulsoft assemblies (version 2021.3.4.0) and the Stimulsoft assemblies are in turn automatically loaded from the same folder as the dynamically loaded assembly.

A 7-Zipped sample project (VS 2019) that reproduces this problem can be found here.

Hello,

Could not load file or assembly 'file:...StimulsoftReports\bin\Debug\CompanyABC.StimulsoftReports.dll' or one of its dependencies. The system cannot find the file specified.'

Thank you.

Hi Lech,

Ensure that the StimulsoftReports project is built before running the WindowsFormsApp1 project; Build -> Build Solution.

As the WindowsFormsApp1 project does not reference the StimulsoftReports project directly (in button1_Click it loads the assembly dynamically), VS will not rebuild the StimulsoftReports project before running the WindowsFormsApp1 project.

Then read the comments in button2_Click to uncomment two lines of code and run the “same” logic but not loading the assembly dynamically.

Hi Lech,

In the forums others have reported this same exception previously but you have never been able to reproduce the problem in your test environment.
I believe the project I provided will allow you to reproduce this problem.

Hello,

We need some additional time to investigate the issue, we will let you know about the result.

Thank you.

Noted. Thanks for the update.

Hello,

Unfortunately, we can not fix this.
We use the TypeConverter functionality in many places, e.g. loading/saving reports with it. Due to the peculiarities of Net Framework implementation, this does not work correctly if assemblies are not loaded explicitly or from the application folder. This is a feature of NetFramework, there is nothing we can do. Sorry.

Thank you.

Hi Lech,

Noted. Thanks for the quick response.

Hello,

You are welcome!
