Could not load file or assembly 'Microsoft.WindowsAzure.Storage' or one of its dependencies

Question

"Could not load file or assembly 'Microsoft.WindowsAzure.Storage' or one of its dependencies. The parameter is incorrect. (Exception from HRESULT: 0x80070057 (E_INVALIDARG))"

Recently got this error when starting a debug of my ASP.NET MVC project. Just out of the blue, haven't touched any of Azure files or configs, or added something since my last succesfull build.

Read this thread but it didn't provide the correct solution for my error:

Could not load file or assembly 'Microsoft.WindowsAzure.Diagnostics' or one of its dependencies

Not sure what kind of files I should display and what parts are imporant. Please someone help?

Answer 1

Try running Fusion Log ( Assembly Binding Log Viewer ) to determine which dependent assembly is missing (or if the application actually can't find the Microsoft.WindowsAzure.Storage for some reason).

Edit: quick tutorial from Hansleman that should get people on the right track: Back to Basics: Using Fusion Log Viewer to Debug Obscure Loader Errors
