Hello,

I have thought a bit more about possible causes for the problem with the assembly reference.
Can you please email me your .vbproj file again (i.e. now, with QuickOPC 2023.1 being referenced as NuGet packages)?

I want to check for possibly unwanted/unnecessary assembly references that might be causing this.

Regards

Hello, thank you.

From the files you have sent, the exception occurs, because the .config file contains

<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
<dependentAssembly>
<assemblyIdentity name="System.Runtime.CompilerServices.Unsafe" publicKeyToken="b03f5f7f11d50a3a" culture="neutral"/>
<bindingRedirect oldVersion="0.0.0.0-5.0.0.0" newVersion="5.0.0.0"/>
</dependentAssembly>
</assemblyBinding>

which means that System.Runtime.CompilerServices.Unsafe assembly should be of version 5.0.0.0.

But, the actual System.Runtime.CompilerServices.Unsafe assembly in your project output is 6.0.0.0.

You need to figure out what is wrong in your project that causes this.
Give me also some time, I will investigate and think of possible causes. But ultimately, it is your task to resolve issues like this.

Hi,

When I try running the Release I get this exception. See the attached zip file - System.Runtime.CompilerServices.Unsafe.zip.
See the attached config file.

See the end of this message for details on invoking
just-in-time (JIT) debugging instead of this dialog box.

<configuration>
<system.windows.forms jitDebugging="true" />
</configuration>

will be sent to the JIT debugger registered on the computer

Thank you. I need some more info.

1) You wrote "when I run my project in debug mode, I get this exception.". What happens if you run the Release configuration?

2) In the target folder of your debug configuration (probably bin/Debug), locate the file System.Runtime.CompilerServices.Unsafe.dll, zip it and post it here. I want to check its version.

3) In the same folder, there should be a file like <you app name>.exe.config . Please post it here. I want to check which binding redirects are in this file.

Hi,

I have defined the components programmatically. See below. When I run my project I get the following exception.

Thank you.

Regarding the missing components: The project seems to be in somehow damaged shape. It should be possible to use the Toolbox to put them back, but I am afraid we would run into even more problem. So, if you can add them from the code, it would be the easiest at the moment.

Hi,

I see that the DA and UA components have disappeared from the form. See below.
EasyUAClient1
UaDataDialog1
DaItemDialog1

When I try to add these components from the Components Toolbox, I get an error. Should I add them programmatically?

Thank you.

Hello,

in your project properties, do you have "Auto-generate binding redirects" checked, as in the example below?

If not, check this setting, save, and rebuild.

Best regards
