ASP.NET CORE 2.20

Created a boilerplate ASP.NET CORE web app project, use kestrel as the web server run without debugging, then making changes to the razor view of the default page being loaded and try to reload the page from the browser. The error I got was

An unhandled exception occurred while processing the request. MissingMethodException: Method not found: 'Microsoft.Cci.IMethodReference Microsoft.Cci.ICustomAttribute.Constructor(Microsoft.CodeAnalysis.Emit.EmitContext)'.

CC @rynowak

Given the exception here is MissingMethodException this would suggest a deployment issue vs. a compiler bug. Have you all seen this before?

rynowak commented 5 years ago

No, I have not seen this before, and I agree with the assessment. This should be using 2.8.0 of Microsoft.CodeAnalysis.CSharp with all its dependencies brought in transitively.

mikefayer commented 5 years ago

Just to clarify for anyone else who stumbles onto this like I did, downgrade the reference to Microsoft.CodeAnalysis.Common from v2.10.0 to v2.8.0 and the problem should be fixed.

downgrade the reference to Microsoft.CodeAnalysis.Common from v2.10.0 to v2.8.0

We were experiencing this same issue, downgrading worked :)
