C# 10 allows initializing 'const' strings using string interpolation, but the placeholder must also be a 'const' string.
— Oleg Kyrylchuk (@okyrylchuk) September 9, 2021
The placeholder can't be a numeric constant cause it's converted to string at runtime.

Starting from C# 10, you can reference nested properties or fields within a proper pattern.
— Oleg Kyrylchuk (@okyrylchuk) September 10, 2021
The property pattern becomes more readable and requires fewer curly brackets \U0001f642

C# 10 introduces a new way of namespace declarations - file scoped namespaces.
— Oleg Kyrylchuk (@okyrylchuk) September 11, 2021
However, you cannot declare a nested namespace or a second file-scoped namespace in the same file.

C# 10 adds a new modifier to a 'using' directive - 'global'.
— Oleg Kyrylchuk (@okyrylchuk) September 12, 2021
It means that 'using' is applied to all files in the compilation.
All 'global using' directives must be before non-global 'using' directives.
It can be combined with a 'static' modifier#dotnet #coding #devcommunity pic.twitter.com/osr3ZPh5AI
In previous versions of #csharp, a deconstruction could initialize newly declared variables or assign all values to existing variables.
— Oleg Kyrylchuk (@okyrylchuk) September 13, 2021
C# 10 can do both assignment and declaration in the same deconstruction \U0001f4aa#dotnet #coding #devcommunity pic.twitter.com/hrBM095jzF
You couldn't add a 'sealed' modifier when you override 'ToString' method in the record type in C# 9.
— Oleg Kyrylchuk (@okyrylchuk) September 14, 2021
In #csharp 10, you can do that.
As in classes, it forbids to override 'ToString' method in the derived record types.#dotnet #coding #devcommunity pic.twitter.com/h4UB7BlmDS
#csharp 10 introduces a record struct. You can declare it with 'record struct' keywords.
— Oleg Kyrylchuk (@okyrylchuk) September 15, 2021
It also adds new syntax for a record class with 'record class' keywords.
A record struct has all struct properties. A record class has all class properties.#dotnet #coding #devcommunity pic.twitter.com/fRR01507ej
Yesterday I tweeted about the new 'record struct' type in C# 10. I showed the way of declaration.
— Oleg Kyrylchuk (@okyrylchuk) September 16, 2021
Let's see today the difference between the new 'record struct' and old fashioned C# 'struct' \U0001f642

Previous C# versions don't support field initializers in the structs.
— Oleg Kyrylchuk (@okyrylchuk) September 17, 2021
C# 10 fixes it and closes the gap between struct and class declarations.
If the struct has field initializers, the compiler will synthesize a public parameterless constructor.#dotnet #coding #devcommunity pic.twitter.com/5XVfU0xQTS
C# 9 has allowed attributes on local functions.
— Oleg Kyrylchuk (@okyrylchuk) September 19, 2021
C# 10 allows attributes on lambda expressions and lambda parameters.
To distinguish expression attribute from parameter attribute, you must use a parenthesized parameter list for lambda expression.#dotnet #coding #devcommunity pic.twitter.com/ITYL1ZBL6c
In C# 10, you can specify an explicit return type for lambdas.
— Oleg Kyrylchuk (@okyrylchuk) September 20, 2021
Explicit return types are not supported for anonymous methods declared with 'delegate { }' syntax.#dotnet #coding #devcommunity pic.twitter.com/jcmeoHgwGj
Since C# 7, you can apply the AsyncMethodBuilder attribute to a type only.
— Oleg Kyrylchuk (@okyrylchuk) September 22, 2021
In C# 10, you can also apply the attribute to a single method.
Disclaimer: the example just shows the applying of attribute \U0001f642#dotnet #coding #devcommunity pic.twitter.com/4QLrz3Tedm
C# 9 has introduced 'with' expression for record types.
— Oleg Kyrylchuk (@okyrylchuk) September 23, 2021
It produces a copy of its operand with the specified properties and fields modified.
In C# 10 you can also use 'with' expression with struct types \U0001f60e#dotnet #coding #devcommunity pic.twitter.com/709NcFVclq
I am quite different from your style. I follow the market's volatility very closely. I have mock positions in 7-8 different strategies which allows me to stay connected. Whichever gives best profit is usually the one i trade in.

Anilji most of the time these days Theta only falls when market moves. So the Theta actually falls where market has moved to, not where our position was in the first place. By shifting we can come close to capturing the Theta fall but not always.
— Sarang Sood (@SarangSood) June 24, 2019
This week has been great so far. The main aim is to be in the right side of the volatility, rest the market will reward.
— Sarang Sood (@SarangSood) July 3, 2019
There is a difference between theta decay & fall in vega. Decay is certain but there is no guaranteed profit as delta moves can increase cost. Fall in vega on the other hand is backed by a powerful force that sells options and gives handsome returns. Our job is to identify them.
