Interpolated strings are supported on .NET 4.6(and above), .NET Core 2.1(and above), .NET Standard 1.3(and above) and UAP 10.0(and above).
For example:
```csharp
string cityName = "London";
int c = 10;
db.Customers
.WhereInterpolated($"City == {cityName} and Orders.Count >= {c}");

users.FirstInterpolated($"Income > {value}");

context.Blogs.CountInterpolatedAsync($"Name.Contains({search})");
```
