Error when running LINQ queries

Post by ShaneFitz » Thu 14 Nov 2019 15:41

Hi I am evaluating using LINQ Insight with VS2019. Whenever I attempt to run a query I receive the following error:

Message: Inconsistent language versions
Parameter name: syntaxTrees
Type: System.ArgumentException
Source: Microsoft.CodeAnalysis.CSharp
Site: CommonLanguageVersion
Stack Trace:

I have disabled IntelliTrace and disabled my ReSharper extension but nothing seems to help? Any ideas?

Thanks in advance.

Thank you for your report. We have reproduced the issue and are investigating it.

JIC: specify your ORM (e.g. Entity Framework 6.2) and C# Language version used in your project (how to check)
