The generated lambda expression is not serialisable! Runtime. Source

In what a difference?And it is interesting, the method needs to be fixed? Execute bash script from vim A guy scammed me, but he gave me a bank account number & routing number. extern "C" HRESULT CallEnumDevicesBySemantics (IDirectInput8 *pDI, LPCTSTR lpsz, DIACTIONFORMAT *pDIAF, LPDIENUMDEVICESBYSEMANTICSCB pCallback, LPVOID pvRef, DWORD dwFlags) { return pDI-> EnumDevicesBySemantics (lpsz, pDIAF, pCallback, pvRef, dwFlags); }In FW2 attribute MarshalAs (UnmanagedType:: FunctionPtr) at System.

GetFunctionPointer (); Console. For the most part, analyzing container registration is straightforward - I only have to detect enough information to know which concrete types are affected.

So, you need to get the predicate Expression into that AppDomain, which means you have to serialize / deserialize it. But I suppose that once it becomes a generic lambda function then all bets are off since they can have references to all sort and so mightn't be easily serialisable anymore. Then I tried integrating the project as a search facility into my blog which is running ASP.Net MVC 3 (.Net 4.0) and ran into another snag; "Inheritance security rules violated while My AccountSearchMapsYouTubePlayNewsGmailDriveCalendarGoogle+TranslatePhotosMoreShoppingWalletFinanceDocsBooksBloggerContactsHangoutsEven more from GoogleSign inHidden fieldsSearch for groups or messages Log in or Sign up Winhost Community Forum Forums > Programming/troubleshooting forums > Site Programming, Development and Design > Strange

WriteLine (y); CrossAppDomainDelegate X = (CrossAppDomainDelegate) Marshal. That library saved me a lot of work. This also contains a delegate to be used for the event. http://www.productiverage.com/compiled-linq-expressions-dont-serialise This requirement is becoming more and more frequent for various reasons.

GetFunctionPointerForDelegateConverts a delegate into a function pointer callable from unmanaged code.RuntimeMethodHandle. Reload to refresh your session.

This makes sence, because the assembly is only being loaded in another appdomain I created.

Here is where it gets tricky. I suspect you need to do some configuration of the JSON.NET serialization engine using the JsonSerializerSettings to enable the serialization of the object you are passing. ‹ Previous Thread|Next Thread › There was something in me that thought that since it had been formed through simple LINQ Expressions tied together that it would be easy to serialise and so not be a

Make a suggestion Dev centers Windows Office Visual Studio Microsoft Azure More... After additional acrobatics (XElement itself isn't marked [Serializable], and this breaks transfer between appdomains), I worked around it by converting to/from a string. However, consider this registration in Castle Windsor: container.Register(Classes .FromAssemblyInDirectory(new AssemblyFilter(".").FilterByName(an => an.Name.StartsWith("Ploeh.Samples.Booking"))) .Where(t => !(t.IsGenericType && t.GetGenericTypeDefinition() == typeof(Dispatcher<>))) .WithServiceAllInterfaces()); (source) Here the information depends on a predicate that will only

If omitted, the default project is used. + +.PARAMETER StartupProject + Specifies the startup project to use. Basically, the user types an equation, and I have a simple parser that interprets the text, builds a lamda expression and compiles into a function delegate with: Dim lamdatree As Expression(Of Would we find alien music meaningful? GetFunctionPointerForDelegate (f); IntPtr y = f.

Then when it's de-serialised I use this data to regenerate the lambdas. // This de-serialising constructor takes the values that are stored in the GetObjectData // method and passes them through This would >ensure that the type would be loadable in both app domains, even if the >files aren't readily available. Since all I can do is statically analyze this, I have in my hand the ReSharper's AST (called PSI in ReSharper) representation of the lambda expression from the Where clause.
