Assembly 'CefSharp' does not have a strong name

[ghost]

Assembly CefSharp is not usable, 'cause is not signed...
I need binary package with signed assembly! :)

[chillitom]

I've fixed some issues with the project files that should allow you to compile the project yourself using VS2010 (i know you were having trouble), can you give that a try. If it works you could sign the assembly yourself. I've not yet decided on my signing and release strategy but this is likely something I will do in the near future.

see: https://msdn.microsoft.com/en-us/library/6f05ezxy.aspx and set the key file under Properties->Linker->Advanced

I try. After studio converts project files:
I set treat wchar_t as built in type: No (/Zc:wchar_t-).
And got linking errors:

Oh, i set in project properties platform toolset to v90 and all was done.
Thanks!

[ghost]

In any way - it's not so good way.

When i compile project with v90 toolset - i got assembly, but it can't be loaded in normal (v4.0) way - "System.IO.FileLoadException: Mixed mode assembly is built against version 'v2.0.50727' of the runtime and cannot be loaded in the 4.0 runtime without additional configuration information."

Of course adding useLegacyV2RuntimeActivationPolicy="true" solve problem with assembly loading, but it is wrong way for new code.

  <startup useLegacyV2RuntimeActivationPolicy="true">
    <supportedRuntime version="v4.0" sku="client" />
  </startup>

Better if we can use v100 toolset, and support targeting to .net 4 client profile.
I understand, that build way of native dlls very depended from libcef_dll_wrapper, what probably builded with previous versions, and maybe c runtime versions mismatch???

[chillitom]

Chromium and CEF can only be build with VS2005 or VS2008. The only mixed mode assembly is CefSharp itself, I am surprised that building this with VS2010 and v90 isn't enough. Maybe there is a way to set the target framework version though I can't see it in the project settings.

I'll hopefully have a copy of VS2010 available to me in the next couple of weeks at which point I'll give it a try myself.

[ghost]

Hmm... In my build HandlerAdapter::HandleAfterCreated never executed - and on load i got null reference exception... :(

[ghost]

I'm fantastic idiot.

1. I found that i have MSVS2008 installed. :)
2. I forget call CEF.Initialize...

For now no any problems.

PS: May be wrong: RaiseConsoleMessage doesn't check that ConsoleMessageEventHandler attached. Also HandlerAdapter create message object even if it is really dosn't not needs.

[chillitom]

glad to hear it's working.

yeah I thought that as well when I first started code C++/CLI, but if you disassemble the generated raise_ConsoleMessage method you can see that if performs a null check in there for you. An unsual case where C++/CLI is more forgiving than C#.

        raise_ConsoleMessage(object value0,
                             class CefSharp.ConsoleMessageEventArgs value1) cil managed

[ghost]

Cool! :)

I have 2 questions:

1. May be BrowserControl have sense do more like as WebBrowser? For example Load vs Navigate, events... etc.
2. Generated events require Invoke, but it is Control and control can handle this internally.
3. Needs event to say that browser is actually ready, and may be wait or throw user-friendly messages in dependend methods. Now Load method throw nullreference exception, if it is executed before internal CEF loop executed HandleAfterCreated. It is usefuly in situations, when i can't use new BrowserControl(url), and use new BrowserControl(), and then (after short period) simply call .Load(url).
4. I don't understand why i got browser uninitialized, when i call in OnLoad method and CEF.Initialize, then create control - looks like CEF loop dosn't executed immediately...

[chillitom]

All good points.. I'm actually working on number 3 at the moment but frames are making it tricky.

Could you do me a favour and open individual issues for each of these suggestions? That'd be superb, this issue is getting a bit off topic.

[ghost]

Okay, i create issues, but little later.

[chillitom]

Issue fixed thanks to fddima.
