Could not load file or assembly 'ClearScriptV8-64.DLL'

[jameskraus]

After following the directions on the ReactJS.NET site, I've been unable to get this to work. I've referenced a few threads here (e.g. #409), but wasn't able to resolve the issue.

Here's the error:

ClearScriptV8-64.dll is in the bin directory of the site.

FWIW, here's Dependecy walker's view of ClearScriptV8-64.dll:

Any ideas what is wrong here?

A few things to try. Does it break if you pick another JS engine like chakra core? Do you have the Visual C++ runtime installed?

It does not break on Chakra core. (I was hoping to use V8 to get some more info out of an error message I've had with server side rendering.) I've got the visual c++ 2015 & 2013 x64 runtimes installed. The site is also set up to run only x64. On Feb 1, 2018 8:16 PM, "Dustin Masters" <[email protected]> wrote: A few things to try.

Hello, James!

What version of the JavaScriptEngineSwitcher.V8 are you using?
In which of subdirectories of bin directory is located the ClearScriptV8-64.dll file?

[jameskraus]

Hey Taritsyn,

Well thanks for the questions about the subdirectory. I found that placing the ClearScriptV8-64.dll & v8-64.dll in a x64 subdirectory got rid of the error and brought my React component to life! (Originally I had them in the root /bin directory).

It seems I misunderstood this part of your misconceptions post:

In this case, native assemblies are located in the x86 and x64 subdirectories of bin[Debug|Release] directory (for web applications and sites just the bin directory).

Thank you!

For the record, I'm using these versions of everything:

[Taritsyn]

… (Originally I had them in the root /bin directory).

Why do it manually, if the JavaScriptEngineSwitcher.V8.Native.win-x64 package itself copies everything to the right place?

[jameskraus]

It didn't copy everything into the right place for me I guess? I suppose its supposed to copy to /bin/x64, but I found the DLLs in the root /bin directory by default.

Everything was installed with nuget and we're using msbuild to build our solution. I'm currently trying to figure out how to get the DLLs to show up in the correct place automatically.

I suspect it's an oddity/bug in our build and deployment process. It might not handle subdirectories in /bin well (we didn't have any before ReactJS.NET).

(And yet for some reason, the ru-ru directory comes out fine??)

(And yet for some reason, the ru-ru directory comes out fine??)

It uses a completely different mechanism (lib directory of NuGet package).

Offtopic: Yesterday you were wrong about the “mebibytes -> megabytes”. I recommend you to see the following code.

Huh, never heard MiB pronounced before. Until now I just assumed it was just a variant of MB. That's what I get for not google-checking Mebibytes.
