1. Create a Unity project in Unity
2. Create a script in Unity
3. Open the script in Visual Studio with Resharper installed
4. Add a new .net project to the solution in VS
5. Add a Reference to the Unity project from the new project
6. Try accessing the Unity project's code from the new project.

ERROR: while the solution compiles, Resharper can't see the Unity project from the new project - there are reference errors, red identifiers, usings, etc.

Just like we do for keywords + live templates.
See the ignored test in postfix completion tests.

This is C# 7.3 netFramework 4.7.1 Unity(auto-generated) project.
Rider (2018.3) states strange error: The modifier 'readonly' is not valid for explicit interface implementation.

I have interface with readonly ref properties.
In the implementing class I want to have both implicit and explicit implementations. Implicit is ok, but with explicit, rider states an error "The modifier 'readonly' is not valid for explicit interface implementation." Though the project builds succesfully.

Not sure if it an ide bug but not found any info about this issue.
Is there any problem with the code?

Sample code:

public interface IA
{
    ref readonly MyStruct Getter { get; }
}

public struct MyStruct
{
    private int i;
}
public class A : IA
{
    private MyStruct i;
    public ref MyStruct Getter => ref i;
    // this is also ok!!
    // public ref readonly MyStruct Getter => ref i;
    ref readonly MyStruct IA.Getter => ref i;
}

Error:

STR:
Open Find usage for an object - it opens like a tab on the form 'Find results'
Open another one Find usage for another object - you'll get two tabs
Click on the second tab - it shows content. Click on the close button on the tab - the first tab becomes an active but content doesn't restore

We have definitly a performance probelm with visual studio, if resharper is installed. The solution loading and slow typing is a big problem. We are Team of 10 Developers and all have the same problem. The solution has 134 projects. what files do you need to tracing?

Best regards

When I refactor AProperty to a getter method, the ? operator is removed from its usage.

The resulting usage line will be changed from: var v = a?.AProperty;
to: var v = a.GetAProperty();
I would expect it to change to: var v = a?.GetAProperty();

public class UsingClass
{
    public void Method()
    {
        var a = new AClass();
        var v = a?.AProperty;
    }
}

public class AClass
{
    private string _aProperty;

    public string AProperty
    {
        get { return _aProperty; }
    }
}

My scenario:

• I have C# UnitTests for MsTest
• I have selected a .runsettings file in VS.
• I have set the R# MsTest option to use the runsettings file from VS UI

When I run the test with visual studio test, it works as expected.
When I run the test with R# the fails because the settings are not loaded.

When I change R# MsTest option and specify the file directly, R# can successful run the tests.
So it seem R# is not finding my VS UI setting anymore.

I have a solution with 90 projects that mixes vcxprojs, old fashioned csprojs and new fashioned csprojs (netcore).

On the old-fashioned csprojs, Intellisense does not find types declared by other projects and their build order is not taken into account while building, leading to failed builds (building again and again will end up with a successful completion as dlls from other projects are successfully built).

To be exact, all works well (Intellisense, build order) until someday it (randomly?) happens on a computer.
Starting from that point, nothing seems to fix it: neither "git clean -fdx" to remove all files not related to the source code from the repository, nor deleting Resharper Caches.

I was not able to reproduce this issue on a simple example... but half of my colleagues have that same issue.
