Enterprise Library 5.0 Activation error occured
※ Download: Activation error occured while trying to get instance of type logwriter, key
CONFIG file should have a section with the ENtLibraries in use. In this layer, you can either opt for ADO.
The issue i am facing is when the Logging message is too large more than 65534 chars ,complete data is not logged in the Formatted Mesage column which is of data Type nText. FeatureActivated SPFeatureReceiverProperties properties at Microsoft. TaskJobInstaller', method 'FeatureActivated' for feature '6805d4ac-8158-4555-8659-4a8815d0e0e1' threw an exception: System.
Error activation LogWriter - Thanks in advance folks.
I have blogged about this error before and this post has become one of my most viewed. I hope it provides the answer you need and it makes sense. Please feel free to leave a comment! Exception occurred while: while resolving. Exception is: InvalidOperationException - The type LogWriter cannot be constructed. You must configure the container to supply this value. It occurs when using Microsoft. EnterpriseLibrary for logging errors. There are lots of blogs that reference this error and they mostly say the error is caused by: a an error in your configuration often the database connection string b not all the DLLs are present That was not my situation. I was logging just to the event log and I was certain I had all the DLLs in the bin directory of my web service. The error occurred when I deployed the web service to a new environment. I spent many hours tracking down the cause. In this case it was because Microsoft. EnterpriseLibrary was installed on the target environment and the DLLs were registered in the GAC. Now as you know,. NET will look for the location of DLLs in a specific order and the GAC is at the top of the list. The problem is, when the Enterprise Library DLLs are installed in the GAC then it is unable to determine the location of the configuration file. Removing the DLLs from the GAC was not an option, I needed to find a way that would work with the DLLs in the bin directory or in the GAC. I have a DLL that I use to simplify the calls when logging an error. It has several constructors to create log entries of different severities. Below is the code that includes just the critical error constructor. Logging public static class Logging public static void LogCritical string message, string title, string category Logger. Write message, category, 3, 1, TraceEventType. Critical, title ; Now I have many places in my code where I reference the LogCritical method and I didn't want to change them. What I needed was a way to link up to the loggingConfiguration section in my web. Firstly I added two additional references and using statements using Microsoft. Configuration; Then I added this method to my class: public static LogWriter CreateLogger EnterpriseLibraryContainer. GetInstance ; return logWriter; What that allows is to create a default container from an XML location that I specify and which in my case contains the loggingConfiguration section. I can then get an instance of the LogWriter class by calling EnterpriseLibraryContainer. Write message, category, 3, 1, TraceEventType. Critical, title ; } Note the lower case L on the logger object. So great, my calls that write to the event log don't need to be changed and I have the ability to specify where my loggingConfiguration section is located. Below is the code for the ReadConfigSource method. Two very important points here. AppDomainAppVirtualPath which will resolve correctly both in debug mode and in deployed mode. Without it the loggingSection. ReadXml xmlReader ; line will fail. ReadXml xmlReader ; xmlReader. Close ; } configSource. SectionName, loggingSection ; } return configSource; } I am pleased with the result. Hope it works for you.
Insults are not welcome. Down load the vsix file Microsoft. So great, my calls that write to the event log don't need to be changed and I have the ability to specify where my loggingConfiguration section is located. Because as per my understanding, is this a mixture of design patterns and some pre-made blocks of source code. I'm new to using the Logging application block. I have added the below line in my code to use the database: using System.
