Wcf large data file

I am trying to upload an image file in base64 format from a angular app. The app is working fine for small images but wcf is giving error of entity too large error for images larger then 200kb. My webconfig file is like this.

I tried previous answers on this site but none seems to be working. I am using framework 4.6.

I suspect you need to add a binding element for the webHttpBinding binding and set maxReceivedMessageSize to something large. The default value is 65536 bytes.
This needs to be set in the system.serviceModel node in the web.config
Below is an example xml set to 5MB
<bindings>
<webHttpBinding>
<binding name="largeMessage" maxReceivedMessageSize="5000000" maxBufferPoolSize="5000000" maxBufferSize="5000000" closeTimeout="00:03:00" openTimeout="00:03:00" receiveTimeout="00:10:00" sendTimeout="00:03:00">
<readerQuotas maxStringContentLength="5000000" maxArrayLength="5000000" maxBytesPerRead="5000000" />
<security mode="None"/>
</binding>
</webHttpBinding>
</bindings>
Could you try updating the services node to explicitely use the binding config (bindingConfiguration attribute equals the binding name attribute). I don't think this is really required as there is only one binding but lets try being explicit.
<services>
<service name="ExamService.ExamService" behaviorConfiguration="serviceBehaviors">
<endpoint address="" contract="ExamService.IExamService" binding="webHttpBinding" bindingConfiguration="largeMessage" behaviorConfiguration="web" ></endpoint>
</service>
</services>
UPDATE
Not sure whats going on here. I made a quick dummy service to replicate the problem.
namespace LargeMessageService
{
[ServiceContract]
public interface ILobService
{
[OperationContract]
[WebGet]
string EchoWithGet(string s);
[OperationContract]
[WebInvoke]
string EchoWithPost(string s);
}
public class LobService : ILobService
{
public string EchoWithGet(string s)
{
return "You said " + s;
}
public string EchoWithPost(string s)
{
return "You said " + s;
}
}
}
When I had a configuration without the binding defined it failed with a 413 as you are seeing. When I added the binding it worked. My full web.config with binding:
<appSettings>
<add key="aspnet:UseTaskFriendlySynchronizationContext" value="true" />

<!--

I was using IISExpress and calling it through Postman by calling the EchoWithPost operation with an xml.
<string xmlns="http://schemas.microsoft.com/2003/10/Serialization/">Hello</string>
replacing 'Hello' with a large string (approx 500K)
Try getting this one to work and if it does its a case of trying to work out the difference between this one and your one. Let me know how you get on.

WCF binding problems

I have problem with my bindings and i dont know how to solve it. I am on the server side and the client is using this binding:
<system.web>
<compilation debug="true" targetFramework="4.5.2"/>
<httpRuntime targetFramework="4.5.2"/>
<httpModules>
<add name="ApplicationInsightsWebTracking"
type="Microsoft.ApplicationInsights.Web.ApplicationInsightsHttpModule,
Microsoft.AI.Web"/>
</httpModules>
</system.web>
<system.serviceModel>
<behaviors>
<serviceBehaviors>
<behavior>
<serviceMetadata httpGetEnabled="true" httpsGetEnabled="true"/>
<serviceDebug includeExceptionDetailInFaults="true"/>
</behavior>
</serviceBehaviors>
</behaviors>
<serviceHostingEnvironment aspNetCompatibilityEnabled="true"
multipleSiteBindingsEnabled="true"/>
<bindings>
<customBinding>
<binding name="pciBinding" receiveTimeout="00:05:00"
sendTimeout="00:05:00">
<textMessageEncoding messageVersion="Soap11WSAddressing10"
writeEncoding="utf-8" />
<httpTransport maxReceivedMessageSize="67108864" />
</binding>
</customBinding>
</bindings>
</system.serviceModel>
<system.webServer>
<modules runAllManagedModulesForAllRequests="true">
<remove name="ApplicationInsightsWebTracking"/>
<add name="ApplicationInsightsWebTracking"
type="Microsoft.ApplicationInsights.Web.ApplicationInsightsHttpModule,
Microsoft.AI.Web"
preCondition="managedHandler"/>
</modules>
<directoryBrowse enabled="true"/>
<validation validateIntegratedModeConfiguration="false"/>
</system.webServer>
I put this also in my config file but the exception is still the same:
The header 'Action' from the namespace 'http://www.w3.org/2005/08/addressing' was not understood by the recipient of this message, causing the message to not be processed. This error typically indicates that the sender of this message has enabled a communication protocol that the receiver cannot process. Please ensure that the configuration of the client's binding is consistent with the service's binding.
What i need to do in order this to works?

You need to add a Endpoint to your config:
<system.serviceModel>
<services>
<service>
<endpoint binding="customBinding" bindingConfiguration="pciBinding" name="MyEndpoint" behaviorConfiguration="myBehavior" contract="Your.Contract.Interface.With.Fullname" />
</service>
</services>
</system.serviceModel>
and you need to give your behaviour a name to bind it on the endpoint, in this example it's called "myBehavior".

I have an issue when deploying wcf service to remote iis,

This runs perfectly on localhost, but when I deploy to the remote server it gives following error,
.Net framework is 4.5
Is any one can help on this?

After spending beautiful night, I found the solution, solution is adding the required library files(.dlls) to the deployed folder bin folder, I was using the EWS for email extraction so I have to add ews library to the bin folder of the published folder, thanks, hops this will help to someone.

WcfTestClient: Failed to add a service. Service metadata may not be accessible

When I go to website and put localhost:23233 into address I can see all the files, also my Service1.svc. But if I try to make WcfTestClient I got error:
Failed to add a service. Service metadata may not be accessible. Make sure your service is running and exposing metadata.
Error: Cannot obtain Metadata from http://localhost:23233/ If this is a Windows (R) Communication Foundation service to which you have access, please check that you have enabled metadata publishing at the specified address...
Please help me.

Based on the error that WcfTestClient is giving you, you are not providing the full endpoint url.
You are adding http://localhost:23233/
You should be adding http://localhost:23233/Service1.svc

Found the solution..

Rather than Copying the whole code from service to cloud proejct, Add a Cloud project in Solution and then right click roles and add existing role from solution.
