I am writing a simple reporting application that pulls data from a SQL database on an external server, and sends out HTML email messages based on said data.
The project builds and executes perfectly 99% of the time, with the exception being after I modify the app.config file. The very first build and run (in Visual Studio 2012 Pro) after modifying the app.config file yields the following error:
"The operation could not be completed. The process cannot access the file because it is being used by another process."
The build succeeds, but this error is generated immediately following build.
I have found several other users with a similar problem, and the solutions were varied. None had the same error for the same reason. A number of people attributed the error to a VS debugger issue.
Has anyone else experienced the same issue, or does anyone know what may cause this? Note that I get the same error in both Debug and Release. The same error is generated even if the connection string is not encrypted.
I have included the app.config file below, as well as all code that accesses config information.
Config File:

I came for advice.I'm trying to connect to the database through C#.But I have a problem with the App config file.It keeps throwing the App exception:,,
Configuration system failed to initialize
".I tried to add ,as advised here:Configuration System Failed To Initialize , but with no positive result.
So I wonder,if there is still a problem in the code,but I rather think that the problem is with the App config file
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<add key="DataSource" value=" My Database'IP adress "/>
<add key="Database" value="My database Name"/>
<add key="Name" value="User name"/>
<add key="Password" value="Password"/>
</configuration>
It seems like you're missing the appSettings element that wraps your key-value collection. It should look more like the following:
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<appSettings>
<add key="DataSource" value=" My Database'IP adress "/>
<add key="Database" value="My database Name"/>
<add key="Name" value="User name"/>
<add key="Password" value="Password"/>
</appSettings>
</configuration>
I am following up the below link and setting a CI set up.
https://blogs.msdn.microsoft.com/visualstudioalm/2015/05/29/testing-in-continuous-integration-and-continuous-deployment-workflows/
The issue I am facing here is with respect to the test settings file. The test are running fine locally. But not remotely when running it, I am getting all test failures.
I believe this is because of the spreadsheet ( where the test data resides ) and the test settings file.
My test settings file is below

All test failed with this error
Data source 'XXX.YYY.aboutThemRecommendationFirstQuarterFlows' cannot be found in the test configuration settings
But I have the settings file in the build steps ( in Run functional Step )
Is there anything I am missing. Any help would be great as I am struggling to find a solutions.
Thanks
According to the error message, it seems that you are referring to a data source named as "XXX.YYY.aboutThemRecommendationFirstQuarterFlows" which does not exist in "App.config" file test configuration settings.
For example, I have a test method use "MyExcelDataSourceTTT" data source:
[TestMethod]
[DataSource("MyExcelDataSourceTTT")]
public void TestMethod1()
{
Assert.AreEqual(TestContext.DataRow["1"].ToString(),"1");
}
But in the App.config file, I only have "MyExcelDataSource" data source. "MyExcelDataSourceTTT" data source does not exist:
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<configSections>
<section name="microsoft.visualstudio.testtools" type="Microsoft.VisualStudio.TestTools.UnitTesting.TestConfigurationSection, Microsoft.VisualStudio.QualityTools.UnitTestFramework, Version=10.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"/>
</configSections>
<connectionStrings>
<add name="ExcelConnection" connectionString="Dsn=Excel Files;dbq=.\testdata.xlsx;defaultdir=.; driverid=790;maxbuffersize=2048;pagetimeout=5" providerName="System.Data.Odbc" />
</connectionStrings>
<microsoft.visualstudio.testtools>
<dataSources>
<add name="MyExcelDataSource" connectionString="ExcelConnection" dataTableName="Sheet1$" dataAccessMethod="Sequential"/>
</dataSources>
</microsoft.visualstudio.testtools>
</configuration>
Now, when run the testing, you will get "Data source 'MyExcelDataSourceTTT' cannot be found in the test configuration settings.." error message.
I'm performing a migration of database, SQL Server to Oracle, in a C# application. The application mentioned, is using Entity Framework to access the database.
In this database there's a procedure that returns a "ComplexType", I researched and found that Oracle does not understand the "ComplexType" and I need to perform the mapping of the output parameter in web.config, then:
<oracle.manageddataaccess.client>
<version number="*">
<implicitRefCursor>
<storedProcedure schema="ALERTA_MPLUS" name="PR_CONSULTA_DADOS_ROBO">
<refCursor name="CV_1">
<bindInfo mode="Output" />
<metadata columnOrdinal="0" columnName="Broker" baseColumnName="Broker" baseSchemaName="ALERTA_MPLUS" baseTableName="tt_Resultado_Final" nativeDataType="Varchar2" providerType="Varchar2" columnSize="50" />
<metadata columnOrdinal="1" columnName="Companhia" baseColumnName="Companhia" baseSchemaName="ALERTA_MPLUS" baseTableName="tt_Resultado_Final" nativeDataType="Varchar2" providerType="Varchar2" columnSize="100" />
<metadata columnOrdinal="2" columnName="Metrica" baseColumnName="Metrica" baseSchemaName="ALERTA_MPLUS" baseTableName="tt_Resultado_Final" nativeDataType="Varchar2" providerType="Varchar2" columnSize="50" />
<metadata columnOrdinal="3" columnName="Q1" baseColumnName="Q1" baseSchemaName="ALERTA_MPLUS" baseTableName="tt_Resultado_Final" nativeDataType="NVarchar2" providerType="NVarchar2" columnSize="50" />
<metadata columnOrdinal="4" columnName="Q2" baseColumnName="Q2" baseSchemaName="ALERTA_MPLUS" baseTableName="tt_Resultado_Final" nativeDataType="NVarchar2" providerType="NVarchar2" columnSize="50" />
<metadata columnOrdinal="5" columnName="Q3" baseColumnName="Q3" baseSchemaName="ALERTA_MPLUS" baseTableName="tt_Resultado_Final" nativeDataType="NVarchar2" providerType="NVarchar2" columnSize="50" />
<metadata columnOrdinal="6" columnName="Q4" baseColumnName="Q4" baseSchemaName="ALERTA_MPLUS" baseTableName="tt_Resultado_Final" nativeDataType="NVarchar2" providerType="NVarchar2" columnSize="50" />
</refCursor>
</storedProcedure>
</implicitRefCursor>
</version>
</oracle.manageddataaccess.client>
This mapping worked perfectly in the development environment, but when I passed the application for approval gave the following error:
I've tried some solutions but none was successful:
ODAC installed on the server approval;
Searching, I found the Oracle documentation that indicates the mapping that way:
<oracle.dataaccess.client>
<settings>
<add name="ALERTA_MPLUS.PR_CONSULTA_DADOS_ROBO.RefCursor.CV_1" value="implicitRefCursor bindinfo='mode=Output'" />

</settings>
</oracle.dataaccess.client>
This is code return the following error (in all environments):
ORA-06550: line 1, colunm 8: PLS-00306:
wrong number or types of arguments in call to
'PR_CONSULTA_DADOS_ROBO' ORA-06550: line 1, colunm 8: PL/SQL:
Statement ignored;
I published the application on another machine (another developer) and also worked;
Some information that I think are necessary:
Visual Studio 2013;
Oracle.DataAcess.dll version 4.121.1.0;
Oracle.ManagedDataAccess.dll version 4.121.1.0;
ISS 7.0;
Pool - Enable 32-bit Applications true;
If you can help me...
Very thanks in advance!
After many trials and errors managed to solve. I do not know if it is the best solution but worked.
In machine.config exists a definition of <oracle.manageddataaccess.client>:
<configSections>
<section name="oracle.manageddataaccess.client" type="OracleInternal.Common.ODPMSectionHandler, Oracle.ManagedDataAccess, Version=4.121.1.0, Culture=neutral, PublicKeyToken=89b483f429c47342" />
</configSections>
So I added this declaration in web.config and it worked perfectly.
I had the same issue and this showed me the way to a solution.
The cause of the issue was that I had installed the OracleManagedDataAccessClient through NUGET but someone else had done a native install of the client. When the client was installed, it created an entry in the Machine.Config. When NUGET installed it created an entry in the Web.config. When trying to execute, I received an error that the section for:
<section name="oracle.manageddataaccess.client" type="OracleInternal.Common.ODPMSectionHandler, Oracle.ManagedDataAccess, Version=4.121.2.0, Culture=neutral, PublicKeyToken=89b483f429c47342" />
Already existed. I commented it out and my service worked but Oracle would fail with the error:
"PLS-00306: wrong number or types of arguments in call"
When the client was installed it was an earlier version of Oracle so the entry in the Machine.config was:
<section name="oracle.manageddataaccess.client" type="OracleInternal.Common.ODPMSectionHandler, Oracle.ManagedDataAccess, Version=4.121.**1**.0, Culture=neutral, PublicKeyToken=89b483f429c47342" />
Since I commented the entry in web.config, the application used the machine.config entry which did not match the actual version.
I modified the entry in the machine.config to match the web.config and everything now works.
I'm doing some work in Visual Studio 2012 Express Edition. I have added an App.config XML file as follows:
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
</configuration>
The first thing that happens is a warning comes up that says "The 'configuration' element is not declared". Does anyone know why this is happening? It looks like elements can not be declared inside of until this is resolved.
Thanks!

Go to XML menu (visual studio top menu item) choose schemas and find for DotNetConfig.xsd and choose Use this schema.
Your problem will resolve for sure
<configuration xmlns="schema URL">
<!-- configuration settings -->
</configuration>
do changes,like above & try
I had the same issue. It is not an error, it is simply a warning; so your application should still compile. I used the following simple config file and the warning is still produced.
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<startup>
<supportedRuntime
version="v4.0"sku=".NETFramework,
Version=v4.5"/>
</startup>
</configuration>
It is an issue that has been raised on the MSDN website, but it does not seem to have been satisfactorily resolved. See link below:
http://social.msdn.microsoft.com/Forums/en-US/Vsexpressvcs/thread/18a1074f-668f-4fe3-a8d9-4440db797439
I had to
-> Go to XML menu (visual studio top menu item) choose schemas and select DotNetConfig.xsd AND RazorCustomSchema.xsd AND EntityFrameworkConfig_6_1_0.xsd
I just had this warning popup inside an autogenerated xml file while working on a xaml project.
Using Debug->Clean Solution and Debug->Rebuild Solution fixed it. Might want to try that before getting fancy with the schemas.
Visual Studio 2013 Express Edition is missing the DotNetConfig.xsd (https://connect.microsoft.com/VisualStudio/feedback/details/817322/dotnetconfig-xsd-files-not-present-in-vs-2013-express-for-desktop).
So to get rid of the warning in VS 2013 Express:
get a copy of DotNetConfig.xsd from another system or from the web (I used https://gist.github.com/eed3si9n/5dd7dd98ad2b3f668928b23477de35a3)
download to C:\Program Files (x86)\Microsoft Visual Studio 12.0\Xml\Schemas
add the schema following Ramakrishna's answer
The warning should be gone.
Choose use this schema. DotNetConfig.xsd
XLM Menu..... Visual Studio
Works perfectly.
I was having less space on my drive which might have resulted in incomplete loading of my application solution. This "the-configuration-element-is-not-declared" problem got solved after i created some space on my drive.
I also got the same warning. After thinking about for some time I realized my error working with SQL (MS SQL).
Warning: the 'configuration' element is not declared
Using C#
App.Config code:
<connectionStrings>
<add name="dbx" connectionString="Data Source=ServerNameHere;Initial Catalog=DatabaseNameHere;Integrated Security=True" providerName="System.Data.SqlClient"/>
</connectionStrings>
*this calls out the database name in the connectionStrings, when I plugged in my SQL code as a practice I always use the database name, schema, then table. This practice didn't carry over well in Visual Studio as I am a beginner. I removed the db name from my SQL syntax and only called from the schema, data table. This resolved the issue for me.
Form.CS:
using (SqlCommand cmd = new SqlCommand("SELECT * FROM [DatabaseName].[Schema].[TableName] WHERE [MEPeriod] = '2020-06-01'", con))
Updated to:
using (SqlCommand cmd = new SqlCommand("SELECT * FROM [Schema].[TableName] WHERE [MEPeriod] = '2020-06-01'", con))
This worked for me, I hope this is found as useful.
Everytime when I open my Solution that is using the Enterprise Library from Microsoft I get this error after building or opening my app.config.
After this Message my Visual Studio is shutting down ! My Configuration hasn't changed for a year and I only got this error just since a few days. I don't know where it comes from and why VS is shutting down after this Message ...
Anyone knows this error maybe ?
My Config looks like this :
<?xml version="1.0"?>

Inserting the configsections into the machine.config solved the problem. Unfortunately I don't understand the reason ...
