Hi,

Im trying to upload Select.HtmlToPdf.dll file using the dw install command.

In the "Addins/Local" folder i have the file "Select.HtmlToPdf.dll".

But in the "Addins/Installed" folder it has a folder called like this.

And when i check under "Developer/Addins/Local" it is called like this and is not "installed" with the green little check that the other of my dll's have

When i check the properties for the dll i can see at the bottom the "original filename" is as the folder in "installed".

So now when i try to install it, it dont want to be installed because it is different names.
How can i solve this? and why does the Developer/addins/local take the originalfilename and not the name which are in assets/local?

And when i try my function that uses it it says: Could not load file or assembly 'Select.HtmlToPdf, Version=25.2.0.0

Regards
Andreas

Hi Andreas,

The "AddIns/Installed" folder requires a specific structure. If you install a dll called "MyLogic.Providers.dll" that has version 1.2.3, it will be installed into a folder called "MyLogic.Providers.1.2.3". The format is "[NameOfAssembly].[Version]". That's the way DynamicWeb handles addins. This happens automatically when installing assemblies using the cli, which is why you see that folder. It's expected and correct. Assemblies not in a matching folder will not be loaded.

I'm not sure what you're referring to when you mention "Developer/AddIns/Local", can you elaborate?

Hi,

I now createad a nuget package instead and run dw install on that file
With depedencies like this:

The select.htmltopdf.dll file seems to work now but this package needs a .dep file to work.
Could not find 'Select.Html.dep' (trying to load C:\Program Files\dotnet\shared\Microsoft.NETCore.App\Select.Html.dep).

But i dont understand how to install the dep file? I thought that when do like this using a nupkg file it should be installed using nuget from DW, which then should add also the .dep file which is required for this package.
Any ideas how to get the dep file in?

Regards
Andreas

Have you checked whether the ".dep" file is copied into the installtion folder after install? If it's not there, try to copy it manually. According to the documentation for Select.HtmlToPdf, you may need to specify the location of the .dep file manually. Technically, that means that you can place it anywhere you like, you just need to specify the path to it.
