How to Resolve 'Method Not Found' Errors in Power BI Integrations: A Step-by-Step Guide
Integrating Power BI into your applications can dramatically enhance data visualization and reporting capabilities. However, developers frequently encounter a 'Method not found' error tied to outdated references, particularly with System.Net.Http.dll
. This article provides a comprehensive guide to resolving these errors, ensuring a smooth integration process with Power BI.
Understanding the Error
The 'Method not found' error typically manifests when attempting to construct a PowerBIClient
instance, indicating a mismatch or outdated reference related to System.Net.Http.dll
. Such discrepancies can hinder your application's ability to communicate with Power BI services, leading to integration failures.
The Error at a Glance:
- Issue: Method not found: 'Void Microsoft.PowerBI.Api.V1.PowerBIClient..ctor(Microsoft.Rest.ServiceClientCredentials, System.Net.Http.DelegatingHandler[])'
- Root Cause: Reference to an outdated
System.Net.Http.dll
version 2.x.x.x.
Step 1: Upgrading System.Net.Http.dll
The first step towards resolving this issue involves upgrading the System.Net.Http.dll
to version 4.0.0.0. This version introduces improvements and bug fixes crucial for Power BI integration.
Upgrade Instructions:
-
Identify the Current Version: Confirm the version of System.Net.Http.dll
your project is using. This information can usually be found in the project's references section within your development IDE.
-
Acquire the New Version: Obtain System.Net.Http.dll
version 4.0.0.0. This can be done through NuGet Package Manager by running the command:
Install-Package System.Net.Http -Version 4.0.0.0
-
Replace the Reference: Update your project to reference the newly downloaded System.Net.Http.dll
.
-
Update Web.config: Modify your web.config
file to reflect the version change as shown below:
<dependentAssembly>
<assemblyIdentity name="System.Net.Http" publicKeyToken="b03f5f7f11d50a3a" culture="neutral" />
<bindingRedirect oldVersion="0.0.0.0-4.1.1.0" newVersion="4.0.0.0" />
</dependentAssembly>
Step 2: Addressing the Compiler Error
After upgrading System.Net.Http.dll
, you might encounter another issue related to System.Object
assembly reference:
- Compiler Error Message: CS0012: The type 'System.Object' is defined in an assembly that is not referenced. You must add a reference to assembly 'System.Runtime, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'.

How to Fix:
This error necessitates an explicit reference to System.Runtime.dll
version 4.0.0.0. Follow these steps:
-
Add to Web.config: Integrate the following snippet into your web.config
under the compilation
node:
<compilation debug="true" targetFramework="4.6.2">
<assemblies>
<add assembly="System.Runtime, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />
</assemblies>
</compilation>
-
Ensure .NET Framework Compatibility: Verify that your project is set to target .NET Framework version 4.6.2 or higher, as compatibility issues might arise with lower versions.
