I’m having a problem, we used a file sending system that was done in Webapplication and we will implement it also in a dll. In Webapplication it is possible to configure in Web.config the maximum file size to be sent, using the tags maxRequestLength (IIS <= 6) or maxAllowedContentLength (IIS >=7). But these same tags don’t work on app. Config da dll and hence generates the error below:

System.Net.WebException: Falha na solicitação com status HTTP 404: Not Found. em System.Web.Services.Protocols.SoapHttpClientProtocol.ReadResponse(SoapClientMessage message, WebResponse response, Stream responseStream, Boolean asyncCall) em System.Web.Services.Protocols.SoapHttpClientProtocol.Invoke(String methodName, Object[] parameters)...

Does anyone have any suggestions on how to set the maximum file size by app.Config?

Can be configured on the web.config of the application that will use this DLL.

I believe you will not be able to configure the application parameters maxRequestLength, maxAllowedContentLength via DLL, as these parameters are global.

Good morning, try setting the two variables in the same file:

Adding the variable "maxRequestLenght":

<system.web>
    <compilation debug="true" targetFramework="4.5.2" />
    <httpRuntime maxRequestLength="2000000" targetFramework="4.5.2" />
 </system.web>

Adding the variable "maxAllowedContentLength":

<security>
        <requestFiltering>
          <requestLimits maxAllowedContentLength="2000000" />
        </requestFiltering> 
 </security>

check if you are authorizing access to the method you are accessing:

<httpProtocol>
 <customHeaders>
<add name="Access-Control-Allow-Headers" value="Content-Type" />
<add name="Access-Control-Allow-Methods" value="GET, POST, PUT, DELETE, OPTIONS" />
 </customHeaders>
</httpProtocol>
